How Can i Use MFC controls in WIN32 App

9-Mar-06 13:11

Just updating, I tried this and it still will not open the window, I just see the executable open in task manager then 1 second later it closes and I never see any window open:

ShellExecute(NULL,_T("open"),_T(".\\cd1\\CBTNuggetPlayer.exe"),NULL,NULL,SW_SHOW);

not sure what else to try. I've gone through the flags to no avail.

Hey all;
i'm just wondering if any1 can help me with this basketball score board i've create ...
The goal of this is to complete a C++ program that reads from the user

- The current quarter (1,2,3 or 4)

- The remaining time to play in this quarter (in min and sec)

- The score of the home team

- The score of the away team

The program should then be able to determine what should be the scoreboard at the end.

The program should output the scores rounded to the nearest multiple of 5.

Note that 2.5 should be rounded to 5.

String Error using ShellExecute() in vs.net 2005

CNewbie8-Mar-06 16:43

Re: String Error using ShellExecute() in vs.net 2005

8-Mar-06 16:43

I am getting an error on this line:

ShellExecute(NULL,NULL,"Cisco CCNP Exam 642-801\\cd1\\CBTNuggetPlayer.exe",NULL,"",SW_SHOWDEFAULT);

and the error is:

error C2664: 'ShellExecuteW' : cannot convert parameter 3 from 'const char [48]' to 'LPCWSTR'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

I am using a relative path as my program will be executed from the root of a CD and will attempt to open a file 2 layer down the directory tree.

thanks

Thanks that fixed the errors and taught me something Smile | :)

. Now it opens CBTNuggetPlayer.exe like it is supposed to but then it closes right away. No Window or anything. Why would that happen?

Thanks

Can't say anything specific. Just a guess, does it require a command line argument?

no, I can go to the exe and double click and it opens fine. it is a GUI based exe. but trying to open it from my program doesnt bring up the window. Just opens the exe and then it closes without a window being drawn.

Try this...

ShellExecute(NULL, NULL, _T("Cisco CCNP Exam 642-801\\cd\\CBTNuggetPlayer.exe"), NULL, NULL, SW_SHOWDEFAULT);

I have to face an assertion when i try to delete some component (textbox, button,and these methods) frequently. After delete these componet and methods, i can't compile successful although it's ok before. It's very difficult for me to modify a project. Can you recommend me the best way to modify these component in Visual C++.
Thanks so much.

hai Thuan,

if you are in MFC, better delete the methods and variables in the ClassWizard.
I think no need to modify the program. And then delte the corresponding component in the dialog box.

Helping others satisfies you...

Hello Thuan
If you are working with Dialog based application, open header file whose name is like CMyDlg(in your case, there is your project's name instead of My. Got it?) and delete all functions and variables associated with that control and then compile. I hope it will solve your problem.
Good luck.

Maybe you forget to delete DDX and DDV code?

I have the same experience because of this reason.

Thuan_pham8-Mar-06 23:18

8-Mar-06 23:18

Can you tell me about DDX and DDV more details.
I have just try the Aqueel's suggestion. I deleted all member variable and function of the Component in .h file, compile and run, everything is OK. But when i delete the component in Resource View Window, i met an Assertion and when i chose Retry to debug, the code have to debug is:
if (hWndCtrl == NULL)
{
TRACE1("Error: no data exchange control with ID 0x%04X.\n", nIDC);
ASSERT(FALSE); -->Point at this row
AfxThrowNotSupportedException();
}
Can i solve this problem.
Thanks you so much.
