I have to export crystal report data into excel.To achieve that, I have written coding like this

MemoryStream oStream;
oStream=(MemoryStream)(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
Response.clear();
Response.Buffer=true;
Response.ContentType="application/pdf";
Response.BinaryWrite(oStream.ToArray());
Response.End();

But i am getting compile-time error such as
"Cannot convert type 'CrystalDecisions.Shared.ExportFormatType.PortableDocFormat' to 'System.IO.MemoryStream' "

Can anyone help point out what mistake i have done on coding.

Thanks in advance

TreeNode with CheckBox

Hello...

I have a problem. I have a treeView and 3 nodes in it with checkboxes.
I want to check only one of the checkboxes. How can I do that ?
That means, if I check the second node, the first & third node must be uncheck automatically.
That can be done using radioButton, but I dont want to use radiobutton.

Any idea ?

Thanks...

Maybe you can loop through the other nodes in the TreeView and uncheck them?

If you try to do this with checkboxes, you are breaking with the whole visual approach that users expect from them and you will only end up confusing. Checkboxes mean that multiple items can be selected. Radiobuttons mean that only one item can be selected. Don't break with Windows conventions unless you have a really good reason to do so.

You can use the textBox.Name property to set the name. If the idea is to distinguish b/w textbox you can consider setting unique value to tag property as well.

Let me know if it helps.

}

I'm getting following exception. I've tried installing exoledb.dll but I could not install it.

e = {"Provider cannot be found. It may not be properly installed."}

Anyone has any idea to install the provider or any other way of reading the mails from exchange server through Code.

Thanks

I got it to run. Others may benefit from this solution.
Just change exoledb.datasource to MSDAIPP.DSO while specifying provider. If anyone has link to a good resource for Exchange server related tasks with dot net Please share it.

Delete Directory

I have a problem deleting a directory, when that directory is already open by another application (like WExplorer, or TCommander). I get the well known exception ".. the process cannot access the file because is used by another application". How can I get around this ? (TCommander as far as I've seen can delete a dir, even if the dir is open by explorer, so something can be done...).

Thanks in advance to all that may give me some info on this problem.

You would have to setup a try catch statement to catch when the exception occurs and see what the program can do to fix the issue, and if it can't you could possibly tell the user which program is causing the error and needs to be closed.

Hi
I think you need to type cast to Memory Stream from ReportDocument. See the sample code below for exporting from Crystal Report to PDF.

MemoryStream oStream; // using System.IO
rptDocument.SetDatabaseLogon(StrUID, StrPwd, StrServer, StrDatabase);
oStream = (MemoryStream)rptDocument.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);

Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/pdf";
Response.BinaryWrite(oStream.ToArray());
Response.End();

I used Crystal Report 10 in VS2005.

it is actually cloning of controls.If i create new object and assign the properties of the copied control to the new object, then after pasting the Changes made in the copied control dialog is reflecting the change in also the pasted control dialog object.
in the above said way i assign the dialog object also directly.

If i use the this.memberwiseClone()to create new object the object is reflecting the dialog values.
