Hi my gridview is below: When i run the project, i cannot see the Textbox on the page. What's my mistake? If i don't add a server-side control, it works. But i have to add a server-side control. ozgur.nevres

Yes i read this. I thought i didn't make a twice call. But after debugging step-by-step on my code, i saw that i made absolutely this mistake. Guess why: To fix another bug. :) I have to always keep in my mind: "When you fix a bug, you may introduce a new bug". Thanks for your response :)

Hi I wrote a windows application. One of my client is sometimes getting the error below. I tested many times, but I never can reproduce the error. Does anyone know about this error?

Hi all, i am writing asp.net using .net framework 2.0 and vs2005. I have 2 buttons (both server side - save and cancel) buttons, 2 requiredfieldvalidators and 1 validationsummary on the page. Page is working correctly at this scenario: - Enter the page - Click "Cancel" button - Button click event works and program enters in btnCancel_Click function. My problem is occuring in the scenario below: - Enter the page - Click "Save" button - Validation summary says "Oppps - you didn't fill the required fields" - Click "Cancel" button - Nothing happens <- PROBLEM IS HERE - Click "Cancel" button AGAIN - Button click event works and program enters in btnCancel_Click function. Does anyone have any idea? Thanks

This is not what i mean. Let me explain my problem: I have WebBrowser object in my form. It navigates some addresses periodically. These addresses sometimes returns an error, like http 404 or 500 or so on. I want to handle these errors in my form. But i could not find a way to do this.

Hi, is there any way to detect http errors (like 404) with .net2.0 WebBrowser object? I have WebBrowser object in my form. It navigates some addresses periodically. These addresses sometimes returns an error, like http 404 or 500 or so on. I want to handle these errors in my form. But i could not find a way to do this.

GREAT! It worked. Many thanks! :beer: And it is better than first one, cz it is using the default browser, not ie only. I changed my default browser to opera, and it opened a new tab in opera. :cool:

Hi all I am using the code below to open an internet explorer window: System.Diagnostics.Process.Start( "iexplore.exe", "http://www.codeproject.com" ); It works well, but in ie7, it opens a new window every time. But i want to open a new tab instead of a new window. Is there any way to do this? Thanks

If i had a chance, i would never, never give that kind of innesential flexibilities to the user. But i am just a developer in a company. So i am developing a program and its backcolor is black. Because a stupid client wants it black. :mad: I changed the DataGridView's backcolor to black, but the scrollbars are still gray, and it looks very ugly. Client does not want this, so i am trying to change their color to black, but i didn't find a way yet, and i don't know even it is possible or not. :confused:

Hi all Is there any way to change a DataGridView's scrollbar color? thanks

i found the problem. If i make any changes in my application, and build it, it re-creates the user.config file in Application Data folder with default values. can i force the VS to re-create the file with changed values? thanks... ozgur.nevres

Hi all, i am trying to change app settings in run time. I wrote the code below: Properties.Settings.Default.ServerIP = "10.0.0.7"; Properties.Settings.Default.Save(); MessageBox.Show( Properties.Settings.Default.ServerIP ); It alerts "10.0.0.7" but does not save the value (default value was 10.0.0.12). And in WindowsApplication1.exe.config file, it is still 10.0.0.12. Does anyone know how can i change this value? Thanks... ozgur.nevres

"But that's when you tell the customer that since IE7 is a Beta product, you won't support that configuration." it is not easy as you say :-) But now i am using .net2.0's WebBrowser component and it is working without a problem. Thanks for your care ozgur.nevres

Thank you, i'll ask it to our clients. But one of our client who is getting this error, has aldready installed ie7.0 Beta. Does it cause the same problem? ozgur.nevres

Hi all, i have a program which is using AxWebBrowser. It was working well under .net framework 1.1. But after upgrading .net framework 2.0, at SOME systems, i receive the error below: System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component. at SHDocVw.IWebBrowser2.Navigate(String URL, Object& Flags, Object& TargetFrameName, Object& PostData, Object& Headers) at AxSHDocVw.AxWebBrowser.Navigate(String uRL, Object& flags, Object& targetFrameName, Object& postData, Object& headers) does anyone know why it occurs, and how can i fix that problem? thanks. ozgur.nevres

I did this. I mean, is there any way to do this automatically. A property, or something... I think the answer is no. Thanks for your care. ozgur.nevres

Hi, i have a problem about datagridview. When i apply a sorting operation on a datagridview, it sortes the items well, but changes the selected item (not selected index). Let me explain this: For example, my sort column's values below: aaa (selected) bbb ccc ddd after sorting: ddd (selected) ccc bbb aaa It changes the selected item. But i want my first selected item will stay in selected. Does anyone know how can i do this? Thanks. ozgur.nevres

Hi all, I wrote a multi-thread application using sockets. But when i attempt to stop a thread, the thread is falling into "AbortRequested" state but never being aborted. Can anyone help me? My code is below: if ( this.m_ReceiveThread.IsAlive ) MessageBox.Show( "alive" ); MessageBox.Show( "State: " + this.m_ReceiveThread.ThreadState.ToString() ); if ( this.m_ReceiveThread != null ) { for ( int i = 0; i <= 10; i++ ) { try { this.m_ReceiveThread.Abort(); this.m_ReceiveThread.Join( 100 ); /* !!!!!! it always says current state is AbortRequested !!!!!! */ MessageBox.Show( "m_ReceiveThread trying to abort. - " + i.ToString() + "\nCurrentState: " + this.m_ReceiveThead.ThreadState.ToString() ); }//End of try. catch { }//End of catch. if ( this.m_ReceiveThread.ThreadState == ThreadState.Aborted || this.m_ReceiveThread.ThreadState == ThreadState.Stopped ) { MessageBox.Show( "m_ReceiveThread aborted." ); break; }//End of if ( this.m_ReceiveThread.ThreadState == ThreadState.Aborted ). }//End of for( int i = 0; i <= 10; i++ ). }// End of if ( this.m_ReceiveThread != null ).

Thanks for your care. Yes, i handle the Closing event. My eventhandler is below: (Note: the error does not occur always, it occurs sometimes ( 1 in 10, average ) private void Server_Closing(object sender, System.ComponentModel.CancelEventArgs e) { if ( !CheckOnlines() ) e.Cancel = true; }//End of Private Method Server_Closing. and my CheckOnlines method: private Boolean CheckOnlines() { int i = this.m_iNumOfOnlineOperators + this.m_iNumOfOnlineVisitors; if ( i > 0 ) { TextObject objTO = ( TextObject ) this.m_htTexts["Server_CheckOnlines_Msg2"]; String strMsg = objTO.TextValue; strMsg = strMsg.Replace( "@", this.m_iNumOfOnlineOperators.ToString() ); strMsg = strMsg.Replace( "$", this.m_iNumOfOnlineVisitors.ToString() ); objTO = ( TextObject ) this.m_htTexts["Server_CheckOnlines_Msg1"]; DialogResult dr = MessageBox.Show( this, strMsg, objTO.TextValue, MessageBoxButtons.YesNo, MessageBoxIcon.Information ); if ( dr == DialogResult.Yes ) { return true; }//End of if ( dr == DialogResult.Yes ). else { return false; }//End of else. }//End of if ( i > 0 ). else { return true; }//End of else. }//End of Private Method CheckOnlines.
