This is a continuation from my earlier thread so all could respond. When I try to open an executable from my program using the following line it opens the executable then immdiatley closes it.:
ShellExecute(NULL,_T("open"),_T("cd1\\CBTNuggetPlayer.exe"),NULL,NULL,SW_SHOW);
The executable is a GUI and it opens fine if I go to the directory and double click on it, but it wont open the window when I try to open it from my program. As I said earlier, I am using a relative path since my program will be at the root of a CD and the executable will be 1 to 2 layers down as it is here.
Anyone know why?
thanks

Using relative paths is *always* asking for trouble. The fact that ShellExecute() doesn't appear to be working indicates that it's not finding the EXE 
How do you know somebody won't copy your CD to a hard disk and run it from there? How do you know what the *current directory* will be when your main program is run. ShellExecute() starts from the current directory, not where the main program lives.
I always figure out where my main program is using GetModuleFileName() and generate absolute paths relative to that.

Yes, I do understand that it starts from the current directory, that is why I start the relative path from the my program will be which is one directory up the tree which would be cd1/CBTNuggetsPlayer.exething I needed to know is the proper format for a relative path so i know I am doing it right.

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.

Hi,
Iam trying to add some controls of MFC to WIN32.
|
|
|
|
|
|
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 . Now it opens CBTNuggetPlayer.exe like it is supposed to but then it closes right away. No Window or anything. Why would that happen?

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);

TEXT("Cisco CCNP Exam 642-801\\cd1\\CBTNuggetPlayer.exe")
or
_T("Cisco CCNP Exam 642-801\\cd1\\CBTNuggetPlayer.exe")

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...
