Hello

I am trying to create a modeless dialog. I have been following examples such as

http://www.codeproject.com/dialog/gettingmodeless.asp

http://www.functionx.com/vcnet/Lesson10.htm

http://www.softlookup.com/tutorial/vc++/vcu21fi.asp#I9

and produced the following code

header file:

 <br />
<br />
#ifndef __CSTARTUPSCREENDLG_H<br />
#define __CSTARTUPSCREENDLG_H<br />
<br />
#include "resource.h"<br />
<br />
<br />
/////////////////////////////////////////////////////////////////////////////<br />

<br />
class CStartUpScreenDlg : public CJPMDialog<br />
{<br />

<br />
CStartUpScreenDlg(CWnd* pParent = NULL);<br />
void CloseStartUpScreen();<br />
<br />
// Dialog Data<br />
//{{AFX_DATA(CAboutDlg)<br />
enum { IDD = IDD_START_UP_SCREEN }; <br />
<br />

main code

<br />
<br />
CStartUpScreenDlg startupDlg;<br />
startupDlg.Create( CStartUpScreenDlg::IDD, this->GetMainWnd());<br />
startupDlg.ShowWindow(SW_SHOW);<br />
startupDlg.SetFocus();<br />
<br />

unfortunately this is not working properly. Although a dialog box appears, the edit box that I want on it does not appear and some static text. If you have any information on what I am doing wrong, please tell me! Thanks for your time.

Create startupDlg on heap.

Try This... and let me know

CStartUpScreenDlg startupDlg;

startupDlg = new CStartUpScreenDlg(); //add this and try

startupDlg.Create( CStartUpScreenDlg::IDD, this->GetMainWnd());
startupDlg.ShowWindow(SW_SHOW);
startupDlg.SetFocus();

hi
so i changed my code to

<br />
CStartUpScreenDlg *startupDlg = new CStartUpScreenDlg();<br />
<br />
startupDlg->Create( CStartUpScreenDlg::IDD, this->GetMainWnd()); <br />
<br />
startupDlg->ShowWindow(SW_SHOW);<br />
<br />
startupDlg->SetFocus();<br />
<br />
<br />

but i am afraid still the dialog box appears but the static text on it does not. it seems creating it on the heap did not help.

Frown | :(

ummm any other ideas ?

See if visible property of edit box having ID IDC_START_UP_INFO is true.

Sure. Don't try to modify the file when it's in use by another process. Smile | :)

Are you sure you are not leaving the file open somewhere?

I am pretty sure that the file is not opened anywhere else..

The error message indicates a sharing violation.

If no other processes are using the file then make sure you haven't opened it twice without
appropriate share flags.
