Hi anyone can help me? i would like to retrieve an image stored in my SQL server from my VB project using ADO... anyone familiarise in it? pls help me... i need it urgently..... tks...
View 1 RepliesOk, the problem is that , i have a field called "Attach" in sql of type image, when selecting it , the field is getting data of type BYTE(). which am being unable to display them on an Image on the panel.
using the following vb.net code:
'Dim sel2 As String
'Dim myCom As SqlCommand
'Dim conn As New SqlConnection
'Dim drr As SqlDataReader
'Dim image As System.Drawing.Image
'sel2 = "select * from attach where att_desc = '" & DropDownList1.SelectedItem().Text & "' and doc_code = " & w_doc_code & " and subcode = " & w_doc_subcode & " and doc_num= " & w_doc_num & " "
'conn.ConnectionString = ("server=developer01;uid=sa;password=aims;database=DVPSOC;timeout=45")
'myCom = New SqlCommand(sel2, conn)
'conn.Open()
'drr = myCom.ExecuteReader()
'If drr.Read Then
' Me.ImageMap1.ImageUrl = drr.Item("attach")
'End If
'conn.Close()
Am getting an exeption on the following line Me.ImageMap1.ImageUrl = drr.Item("attach")
saying: Conversion from type 'Byte()' to type 'String' is not valid.
knowing that i tried converting using ToString but it's not getting any output then.
thanks for your help.

Hi, I'm stuck trying to figure out how to call an image from the database by certain ids. I want to get it like this: page.aspx?pictureid=#&userid=#
here's the show.aspx:Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim PictureID As Integer = Convert.ToInt32(Request.QueryString("ppID"))Dim MemberID As Integer = Convert.ToInt32(Request.QueryString("mID"))
'Connect to the database and bring back the image contents & MIME type for the specified pictureUsing myConnection As New SqlConnection(ConfigurationManager.ConnectionStrings("objConn").ConnectionString)
Const SQL As String = "SELECT [ppMIMEType], [ppImageData] FROM [tblPP] WHERE ([ppID] = @ppID) & ("[mID] = @mID)"Dim myCommand As New SqlCommand(SQL, myConnection)
myCommand.Parameters.AddWithValue("@ppID", PictureID)
myCommand.Parameters.AddWithValue("@mID", MemberID)
myConnection.Open()Dim myReader As SqlDataReader = myCommand.ExecuteReader
If myReader.Read ThenResponse.ContentType = myReader("ppMIMEType").ToString()
Response.BinaryWrite(myReader("ppImageData"))
End If
myReader.Close()
myConnection.Close()
End Using
End Sub
here's the formview to display image with datasource:
<asp:FormView ID="PictureUI" runat="server" DataKeyNames="ppID,mID" DataSourceID="PicturesDataSource" AllowPaging="False" EmptyDataText="There are currently no pictures uploaded" HorizontalAlign="Center" CellPadding="0">
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("ppID", "~/Show.aspx?ppID=" & 1 &"mID=" & 1 &"") %>' />
</ItemTemplate>
</asp:FormView>
<asp:SqlDataSource ID="PicturesDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:Connect %>"
SelectCommand="SELECT [ppID], [ppDateTime], [mID] FROM [tblPP] ORDER BY [ppDateTime]">
</asp:SqlDataSource>

Hello,
I have not seen a response to this specific question so here goes. I had working code for loading an image into my smart device SQLCE db and for retrieving images. But after upgrading my application to SQLCE 2.0 I am unable to use my retrieve code. This is what was previously working,
Dim ImageBytes As Byte = rs.GetValue(rs.GetOrdinal("OLE"))
Dim ImageStream As New System.IO.MemoryStream(ImageBytes)
frmFlashcardActive.picboxBlobToPicBox.Image = New Bitmap(ImageStream)
Help!
This is what I successfully use to save the image to the database
Dim PictureInfo As New FileInfo("My DocumentsUSAFlag.bmp") 'OpenDialog.FileName
Dim PictureSize(PictureInfo.Length) As Byte
If PictureSize.GetValue(0) <= 69 Then
Dim fsPicture As New FileStream(PictureInfo.FullName, FileMode.Open)
Dim PictureReader As New BinaryReader(fsPicture)
PictureReader.Read(PictureSize, 0, PictureSize.Length)
'find the previous record and add the picture
rs.SetValue(rs.GetOrdinal("OLE"), PictureSize) 'could be FlashcardAPic
rs.SetValue(rs.GetOrdinal("Picture"), "True")
rs.Update()
fsPicture.Close()

where
Code Block

For some reason in a Team Foundation Team Project that has multiple project types (SSRS, SSIS, WebSite, C# Business DLL...), the SSIS project makes itself the startup project to the team project. If I explicitly set another project as the startup project to the team project and then select an SSIS package in the SSIS project in the team project, the SSIS project becomes the startup project automatically.
I am using Visual Studio 2005 SP1.

View 1 Replies View RelatedI am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.

Hello,
I've created a Report Model Project that can be used by Report Builder to generate ad-hoc reports. I'm trying to create a connection string in my Report Server Project that points to the Report Model Project data source view.
All I can do is create a regular datasource, which bypasses the metadata contained in the Data Source View.
Basically I want my Report Server Project and my Report Builder reports to leverage the same metadata. Is this possible? If so how do I get the connection string?
Thanks!!

This is kind of a visual studio question, but pertinent to db' s - due to many changes of our application I know that there are many stored procs in the database that are no longer used. Since I cannot get a list from the programmers, is there any way to get a list out of visual studio, of every SQL stored procedure called in that project? (Going through each form manually will just be too time consuming for me or the programmers)
Anyone know any tricks??
thx

Hi, Can anyone please help me solve this problem.
My functions works well with this stored procedure:
CREATE PROCEDURE proc_curCourseID@studentID int ASSELECT * FROM StudentCourse WHERE mark IS NULL AND studentID = @studentID AND archived IS NULLGO
But when I applied the same function to the following stored procedure
CREATE PROCEDURE proc_memberDetails@memberID int ASSELECT * FROM member WHERE id = @memberIDGO
I received this message
Exception Details: System.Data.SqlClient.SqlException: Procedure or function proc_memberDetails has too many arguments specified.Source Error:
Line 33: SqlDataAdapter sqlDA = new SqlDataAdapter();
Line 34: sqlDA.SelectCommand = sqlComm;
Line 35: sqlDA.Fill(dataSet);
Line 36:
Line 37: return dataSet;
The function I am using is returning a DataSet as below:
public DataSet ExecuteStoredProcSelect (string sqlProcedure, ArrayList paramName, ArrayList paramValue)
{
DataSet dataSet = new DataSet();
SqlConnection sqlConnect = new SqlConnection(GetDBConnectionString());
SqlCommand sqlComm = new SqlCommand (sqlProcedure, sqlConnect);
sqlComm.CommandType = CommandType.StoredProcedure;
for (int n=0; n<paramName.Count; n++)
{
sqlComm.Parameters.Add(paramName[n].ToString(),Convert.ToInt32(paramValue[n]));
}
SqlDataAdapter sqlDA = new SqlDataAdapter();
sqlDA.SelectCommand = sqlComm;
sqlDA.Fill(dataSet);
return dataSet;
}
If this is not the correct way, is there any other way to write a function to return a dataset as the result of the stored procedure?
Thanks.
I have a stored procedure that return either 1 or -1 : IF EXISTS( ) BEGIN return 1 ENDELSE BEGIN return -1 ENDAnd then I try to retrieve the returned value by doing this:int value = Convert.ToInt32(command.ExecuteScalar());But the value I get is always 0. Anyone see what is wrong?
