Access To Variables In Custom Log Provider?
Jun 29, 2006
Hello,
I found one post from the past asking this question, but didn't see an answer, so I am hoping someone can shed some more light on it:
I am writing a custom log provider in C#. Is it possible give this custom log provider access to the variables collection (via a variabledispenser object)? First glance at the log provider classes would tell me that this is not possible, though I would like confirmation. Also, if I am correct in thinking it is not possible, what was the reason for leaving this out?
Thanks!

Hi,
Given that Task.Validate() exposes the package's VariableDispenser, but LogProviderBase.Validate() doesn't...
http://msdn2.microsoft.com/fr-fr/library/microsoft.sqlserver.dts.runtime.task.validate.aspx
http://msdn2.microsoft.com/fr-fr/library/microsoft.sqlserver.dts.runtime.logproviderbase.validate.aspx
...I guess that simply means that I can't access a package's variables within a custom log provider? Can anyone comment/confirm? Any other options/routes to achieving the same..?
We live in hope,
Tamim.

As far as I can make out it is not possible to access the variables collection from a custom log provider.
I'm interested to know what the rationale for this is. Why aren't the variables available for logging purposes?
Thanks

I am interested in determining if package variables can be read from a custom log provider. I am able to pass the values into the custom log provider using an expression in a custom connection manager. My intention is to used the values of these variables upon package failure so I can capture the context of the failure. Unfortunately, if the value of the variable is changed at runtime, this update is not reflected in the custom log provider.
Is it possible to get direct access to the package variables from the custom log provider?
Thanks,
Marc

Hi Everyone,
I created a script task that uploads a file to a HTTPs site. The script task works well and now I want to turn this script task into a custom component...
I'm having problems on how to call the variables I have in the package, I already locked them for reading, but how am I suppose to access them and how can I put their values into strings so I can easily call them in the WebClient.UploadFile method?
Also, I am very new to custom tasks in SSIS.. and would appreciate if anyone of you can send me something (code, link, etc.) of a very simple custom task without any form or properties, that I can try to study.
Basically, what I want my custom task to do is,
1. Read the varialbes in the package.
2. use the variables values as input in my WebClient.UploadFile("varURLstring", "PUT", "varFilePath")
as you can see, my custom task is really simple... but I'm a noob here and I don't know where to go.
Thanks in advance,
Kervy

Hi,
I'm trying to simplify the deployment process of my project. I already had some troubles with the config files but lets say I solved that issue. I'm going to read a flat file and set the variables of my packages from this file. I was thinking to use a Script Task to do that but I will need to copy this task in every package (I have at least 30). So if I want to make some change this will be painful.
Then, I came up with the idea of creating a Custom Task called Config File Task. I'm working on this but I got stuck trying to get the variables from the package that is running my Config File Task.
This is the code I had in the Script Task:
Dim streamReader As New StreamReader(Dts.Variables("ConfigFilePath").Value.ToString)
Dim line As String
Dim lineArray As String()
Dim variableName As String
Dim variableValue As String
Dim readConfigurations As Boolean = False
While (streamReader.Peek() <> -1)
line = streamReader.ReadLine()
If line = "[CONFIGURATIONS]" Then
readConfigurations = True
ElseIf line = "[/CONFIGURATIONS]" Then
readConfigurations = False
Else
If readConfigurations And line <> "" Then
lineArray = line.Split("|".ToCharArray())
variableName = lineArray(0).Trim()
variableValue = lineArray(1).Trim()
If Dts.Variables.Contains(variableName) Then
Dts.Variables(variableName).Value = variableValue
End If
End If
End If
End While
Dts.TaskResult = Dts.Results.Success
All I want to do is set the variables that exists in each package from the config file. In my UI Class (ConfigFileTaskUI.cs) I can have access to the variables via the TaskHost which is passed as an argument of Initialize() method.
Any thoughts? I'd really appreciate some help!
P.S. I've been working on this for 2 days!

I am new to SSIS but I am learning fast. Any help is greatly appreciated.
I have written a custom log provider derived from LogProviderBase. I want to programmtically add the custom log provider to my package, but when I try this:
myPackage.LogProviders.Add("ACustomLogProvider");
I get the following exception:
"The log provider type "ACustomLogProvider" specified for log provider "{..GUID..}" is not recognized as a valid log provider type. This error occurs when an attempt is made to create a log provider for unknown log provider type. Verify the spelling in the log provider type name".
I have followed the instructions in BOL and as suggested in this forum, adding the DtsLogProvider attribute:
[DtsLogProvider(DisplayName="ACustomLogProvider", LogProviderType="ACustomLogProvider", Description="a description")]
Another way I tried is that I added a GUID attribute to my custom log provider class and then tried this:
Type aType = typeof(ACustomLogProvider);
Guid aGUID = (Guid)aType.GUID;
myPackage.LogProviders.Add("{"+ aGUID.ToString() +"}");
This also gives me the same exception "The log provider type ""{..the actual GUID for ACustomLogProvider..}" specified for log provider "{..a different GUID..}" is not recognized as a valid log provider type....
My questions are: Is it possible to add a custom log provider programmtically or must it be done through the SSIS Designer?
Must I deploy my custom log provider class for it to work programmatically? (I had perhaps wrongly assumed I would not have to deploy if I don't want it to show up in the SSIS Designer).
I would prefer to use a custom log provider instead of just logging within the SSIS event handlers because I can override the OnPostExecute, etc. but I cannot (can I?) override the specific event handlers like PackageStart, PackageEnd, etc because they are not exposed through DTSEvents.
Any help I would be very grateful for. Thanks.

Hi All,
I have a tricky one for you...
1. I create a custom log provider on machine A.
2. I deploy the signed assembly to the../../DTS/90/LogProviders directory & the GAC on both machine A & machine B.
3. I create a new package on machine A & go to enable logging for this new custom provider: I find it in the drop-down list of providers, and I can add it successfully.
4. I create a new package on machine B & go to enable logging for this new custom provider: I find it in the drop-down list of providers, but I can't add it. I get the following error:
'...failed to create log provider...the log provider type "_" specified for log provider "_" is not recognized as a valid log provider type. This occurs when an attempt is made to create a log provider for an unknown log provider type. Verify the spelling in the log provider type name (package)."
Any ideas anyone??

Hi...
I am trying to do custom log provider that will post events to Notification Services...The idea is that if I could post the "SSIS events" to Notification Services, with a Custom Delivery Channel in NS, I would be able to do NS Subscriptions with real time monitoring of SSIS packages..
I have tried to use the sample custom log provider code in MSDN. The problem is after I added the custom log provider dll to the C:Program FilesMicrosoft SQL Server90DTSLogProviders folder and install to global assembly using gacutil...
The custom log provider is not showing up in the Provider Type under Configure SSIS logs...

ASP.NET 2.0....
What is the proper way to rename the ASPNETDB.MDF to another name, such as TEST_ASPNETDB.MDF?
I know you can rename the db in the IDE, BUT, there are other places you need to change so that ASPNETDB.MDF isn't recreated. Do I have to make a custom SQLExpress provider or something to that effect?
Any examples? Thanks...

Hi,
I'm trying to use an OLE DB connection manager from inside a custom log provider, but can't get the code to work - I get an exception "A first chance exception of type 'System.InvalidCastException' occurred in SSEALogProvider.dll" on the last line of the code below.
I know the connection is OLE DB from looking at .CreationName.
I've tried both with & without ToConnectionManager90(), but appearently not in the right way, both cases gives the same exception.
Any tips on what I'm missing? All the examples I've seen are either creating (instead of using) connection managers, or are file based connection managers. Any and all help much appreciated!
Thanks/Kristian
if (this.ConfigString.Length == 0 || connections.Contains(ConfigString) == false ||
connections[ConfigString].CreationName != "OLEDB")
{
infoEvents.FireError(0, "SSEALogProvider", "The ConnectionManager " + ConfigString + " specified in the ConfigString property cannot be found in the collection, or is of the wrong type (expected CreationName='OLEDB'.)", "", 0);
return Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure;
}
else

public override void OpenLog()
{
if (!connections.Contains(this.ConfigString))

Hi,
I have a package with a custom log provider, which runs in BIDS. However when I deploy the package onto SQL Server and run it on the deployed machine, if fails:
"failed to decrypt protected XML node DTS:Password...key not valid for use in specified state..."
Now this is definately to do with the custom log, as if I take it out & redeploy, I can run it on the deplyed server + also run it within a job. I have entered the custom log provider library (+ other required DLLs) in the GAC on the deployed machine, but I'm clearly missing something.
Any ideas pls??? I'm really stuck.
Many thanks in advance,

Hello all,
I have been struggling trying to read and/or write package level variables from within my custom task. I'd like to be able to get and set values from within the Execute method of my custom task. I have searched this forum and the books online and can't seem to find the answer. I thought maybe I could use an expression on my task (mapping the package variable to a custom task public property) but that doesn't seem to be working for me. I also would have thought I could use the VariableDispenser object from within my task but the collection is empty. I have 3 package level variables configured and can't seem to find a way to access them (with intentions of getting/setting). Could someone point me to a good doc or provide an example that may accomplish this? Thanks!
(I'm using package level variables as a means of passing simple information between tasks that are not using a DB, if there is a better way I'm open to suggestions.)

In a previous post in Installation and Setup I was having problems just getting an ASP.NET 2.0 app to run on my web server. Now I'm having some different weird security issues.
I'm getting this message when just trying to open a database and put its contents into a gridview.
Access to the ADO.net Managed Provider 'SqlClientFactory' was denied in the data source with ID 'sqlEmployees' because of security settings.
I think this may have to do with our web server and our SQL server being separate machines. That always gives us issues. But I have impersonation=true in my web.config along with windows authentication and I have SQL Server configured with Windows and SQL authentication so things should be right, I'm thinking.
Any ideas??

You must access this provider through a linked server."
I am using VB 6.0 as front end. Is there anyway i can overcome this error?

I am trying to find ways around the limitation of not being able to resize columns based on the text input. I am dynamically setting what values a column is getting from my query. I am wondering if I can access the table (and thus, the columns) from within the custom code.
For example:
Public Function Whynot() As Integer
Report.table1.TableColumn1.Width = ....
table1.TableColumn.Width = ....
Return 0
End Function
Neither of these seem to work, anyone else have any ideas?
Thanks

Hi,
I have created a view. However this view needs a specific variable that a user has inputted in Access. The variable I need to pass into the first view is a DocketID..Similar to a StoreID. I then must run the second view, which also depends on the same DocketID. Finally I must run a final query that takes the result from the second view, which takes the results of the first view.
Basically, I want to pass the variable from my VBA application to the SQL statement. I have been reading, and it seems that like in VB I must declare a local variable in a DECLARE statement. Is that right?
How would I pass the variable that can be held in the VBA application ex. DocketId = 220 and pass that 220 to my SQL statement which is running is SQL 7.0. Most of the statement will be running in SQL, not the VBA application.

Hey all...I'm pretty new to SSIS packages and things are coming along nicely. My problem is accessing variables in script tasks.
I've created two variables (package scope, strings, readonly = false) - aDetailFiles and strDetailFile
Within a Foreach Loop I loop through a folder. I've added a script task and within that I try the following:
Dts.Variables("User::aDetailFiles").Value = Dts.Variables("User:trDetailFile").Value.ToString() + "|" + Dts.Variables("User::aDetailFiles").Value.ToString()
Everytime this script executes I get the following errors:
at Microsoft.SqlServer.Dts.Runtime.Variables.get_Item(Object index)
at ScriptTask_feac87c947ce4431a4fee0ba0e13631d.ScriptMain.Main() in dts://Scripts/ScriptTask_feac87c947ce4431a4fee0ba0e13631d/ScriptMain:line 25
I have searched this error message but the only thing I found was to set the ReadWrite variable property but I don't know where to set that.
Expresion property set as false also.
Any ideas? Thanks.

Hallo
i'm trying to connect a VFP DBC as a linked server on MSSQL2000sp3a, using following parameters:
Product name: VFP
Data source: \networkpath odbc
Provider: VFPOLEDB.1
No security context
I'm trying the same operation both from a W2000sp4 server (+ MDAC 2.8sp1 ?) and a WXPPsp2, against two identical copies of the DBC that resides on two different path (one on the final path and one on a test path).
From WXPPsp2 everything runs ok, from W2000 i'm always getting this error:
Error 7399: OLE/DB Provider 'VFPOLEDB' IUnknown::QueryINterface returned 0x80070005: Access Denied
(already reported in this thread, http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1832362&SiteID=1 but it didn't helped me)
The error happens independently from the user the query runs under (basicly AD account, both domain admin and normal user).
MSSQL runs under a domain account which have full permissions (for test purpose) on the directories where DBC reside.
I did no further modifications on the WXP machine in order to have the linked server running, simply it ran smoothly from the beginning.
Clearly the difference rely on the different OS... but what else?
i ran component checker to determine the MDAC version but some components version numbers slightly differs from the expected ones (eg. resulting version is 2.0.1064 versus 2.0.1022 expected in MDAC 2.8) so i suppose to have MDAC2.8 sp1 on the server.
thanks in advance
