I want to check only one of the checkboxes
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.
Deja View - the feeling that you've seen this post before.

I am hoping someone can help, I have created a form which is populated at specific locations with textbox's at runtime, what i would like to be able to do is set the name of the textbox's when they are created from a specific string which would change for each textbox.
I am hoping someone can tell me how to do this, thank you for any help.

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.

Hi I'm using C#2.0 to read mails from Exchange Server 2003 through following code.
namespace ReadOutlook<br />
{<br />
class Class2<br />
{<br />
public void read()<br />
{<br />
try<br />
{<br />
ADODB.Connection oCn = new ADODB.Connection();<br />
ADODB.Recordset oRs = new ADODB.Recordset();<br />
<br />
ADODB.Fields oFields;<br />
ADODB.Field oField;<br />
<br />
string sFdUrl = "http://Exchange/Exchange/UserId/Inbox";
<br />
oCn.Provider = "exoledb.datasource";
oCn.Open(sFdUrl, "", "", -1);<br />
<br />
if (oCn.State == 1)<br />
{<br />
Console.WriteLine("Good Connection");<br />
}<br />
else<br />
{<br />
Console.WriteLine("Bad Connection");<br />
}<br />
<br />
<br />
string strSql;<br />
strSql = "";<br />
strSql = "select ";<br />
strSql = strSql + " \"urn:schemas:mailheader:content-class\"";<br />
strSql = strSql + ", \"DAV:href\" ";<br />
strSql = strSql + ", \"urn:schemas:mailheader:content-class\" ";<br />
strSql = strSql + ", \"DAV:displayname\"";<br />
strSql = strSql + " from scope ('shallow traversal of " + "\"";<br />
strSql = strSql + sFdUrl + "\"') ";<br />
strSql = strSql + " WHERE \"DAV:ishidden\" = false";<br />
strSql = strSql + " AND \"DAV:isfolder\" = false";<br />
<br />
<br />
oRs.Open(strSql, oCn,<br />

<br />
<br />
oRs.MoveFirst();<br />
<br />

<br />
string sUrl;<br />
oField = oFields["DAV:href"];<br />
sUrl = oField.Value.ToString();<br />
<br />

<br />

<br />
<br />
for (int i = 0; i < oFields.Count; i++)<br />
{<br />
oField = oFields[i];<br />
Console.WriteLine("{0} : {1}", oField.Name, oField.Value);<br />
}<br />
<br />
<br />
oRs.Close();<br />
oCn.Close();<br />
<br />
oCn = null;<br />
oRs = null;<br />
oFields = null;<br />
oField = null;<br />
}<br />
catch (Exception e)<br />
{<br />
Console.WriteLine("{0} Exception caught.", e);<br />
}<br />
}<br />
}<br />
}
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
Don't Quit

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.
Thanks

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;
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.
Rate this message. Thank you. Harini

How to copy objects in c#. If we use clone method Pasted objects reflect the changes done in copied objects.
|
|
|
|
|
what's and where is the need
enlight us more
|
|
|
|
|
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.
|
|
|
|
|
|
The control object to be copied has some other objects also.
|
|
|
|
|
Hello,
I would recomend to make properties for this objects!
All the best,

i had write this code using c# to do drag and drop. But it just for drag and drop. i need it to reorder itself after the drag and drop. how can i fix this code to do the reorder?
private bool isDragging=false;
public int x,y;
private void panel1_MouseDown(System.Object sender,
System.Windows.Forms.MouseEventArgs e)
{
isDragging = true;
x = e.X;
y = e.Y;
}
private void panel1_MouseUp(System.Object sender,
System.Windows.Forms.MouseEventArgs e)
{
isDragging = false;
}
private void panel1_MouseMove(System.Object sender,
System.Windows.Forms.MouseEventArgs e)
{
if (isDragging == true)
{
panel1.Left = e.X + panel1.Left - x;
panel1.Top = e.Y + panel1.Top - y;
}
|
|
|
|
|
onMouseUp Event Check if isDragging id true the check the location of other control and then reorder accordingly
|
|
|
|
|
Thanks for the idea. It's very useful. But i have the problem to check the location of other control. Can you give a example or idea?
