I have been using a mfc dll for some functions I call from winrunner scripts for testing. I decided to create a dialog for the test in a new MFC appwizard exe project. Now I have the gui set up and a bit of code working behind it how can I put this inside my origional dll? 
I can see where the form is created:
CGUITestDlg dlg;
m_pMainWnd = &dlg;
int nResponse = dlg.DoModal();
If I put this code inside inside a function in my dll will calling it make the form popup? Im new to the VC6 interface and am not sure if I can just copy the code or merge the projects somehow???
Thanks

I have a problem related to my project.
The project is designed like this:
Two different users(Super user & normal user) have two different menu. If I login as a normal user first. Some menu items will be deleted according to limitation of normal user. Then I logoff and login again as a super user(notice: without closing the window and application). Then it should show the whole menu items(since super user can see anything) if I use file open or file new. But unfortunatly the menu still is the non superuser menu.
This happens becsause MFC initiates the frame or menu once and then uses the shared menu later on.
I'm think of reloading the menu or frame from rc file again to solve this problem. But I wondered how I can do it or if you guys can think another way to solve this problem.
Thanks in advance!
Thanks very much
Amber
Thanks very much

Before the menu is displayed you need to check who is logged on and then use InsertMenu or RemoveMenu as necessary.
if( Super )
{
menu.InsertMenu(...)
}
else
{
menu.RemoveMenu(...)
}

I need to do the same thing that the javascript unescape function does but in C++. Is there a library function or , some class that can do this for me?
e.g hello+this+is+the+message
would become: hello this is the message
but of course there are all the special characters %0D ect
Thanks.

UrlUnEscape
[This is preliminary documentation and subject to change.]
Converts escape sequences back into ordinary characters.
HRESULT UrlUnEscape(
LPTSTR pszURL,
LPTSTR pszUnEscaped,
LPDWORD pcchUnEscaped,
DWORD dwFlags
);
Parameters
pszURL
[in/out] Pointer to a NULL-terminated string with the URL. If dwFlags is set to URL_UNESCAPE_INPLACE, the converted string is returned through this parameter.
pszUnEscaped
[out] Pointer to a NULL-terminated string containing the unescaped version of pszURL. If URL_UNESCAPE_INPLACE is set in dwFlags, this parameter is ignored.
pcchUnEscaped
[in/out] Number of characters in the buffer pointed to by pszEscaped. On entry, the value pcchEscaped points to is set to the size of the buffer. When the function returns, the value pcchEscaped points to is set to the number of characters written to that buffer, not counting the terminating NULL character. If an E_POINTER error code is returned, the buffer was too small, and the value pcchEscaped points to is set to the required number of characters in the buffer. If any other errors are returned, the value that pcchEscaped points to is undefined.
dwFlags
[in] Flags that control which characters are unescaped. It can be a combination of the following flags. Flag Description
URL_DONT_UNESCAPE_EXTRA_INFO Don't convert the # or ? character, or any characters following them in the string.
URL_UNESCAPE_INPLACE Use pszURL to return the converted string instead of pszUnEscaped.
Return Values
Returns an OLE success code if successful. If the URL_UNESCAPE_INPLACE flag is not set, the value pointed to by pcchUnEscaped will be set to the number of characters in the output buffer pointed to by pszEscaped. Returns E_POINTER if the URL_UNESCAPE_INPLACE flag is not set and the output buffer is too small. The pcchUnEscaped parameter will be set to the required buffer size. Otherwise, returns an OLE error value.

Hi all,
In my program, given a process ID, I want to know what resources (esp. ports) the process or threads under that process are using. How do I do this? Any help,suggestions,links will be useful.
TIA.

Hi everyone!
I'm trying to learn stl, resisting the temptation to reinvent the wheel repeatedly, but I'm running into an initial problem.
typedef std::list<socket*> SOCKLIST;
function(SOCKLIST sockets_) {
SOCKLIST::iterator it;
for (it=sockets_.begin(); it<sockets_.end(); it++)="" {
...
}
}
this="" makes="" an="" error="" in="" the="" 'for="" (...'="" line.="" i="" think="" it="" doesn't="" like="" it<sockets_.end()="" statement.="" cryptic="" (to="" me)="" message="" follows:
bool="" __cdecl="" std::operator="" <(const="" class="" std::list<_ty,_a=""> &,const class std::list<_Ty,_A> &)' : could not deduce template argument for 'const class std::list<_Ty,_A> &' from 'class std::list

Ok sorry.
the < should be a !=
|
|
|
|
|
You are missing a type
typedef std::list<type> SOCKLIST;
where type can be int, char, string, a class, structure etc.
|
|
|
|
|
The forum ate my code. Since it probably ate your code to I'm not sure if this is the correct answer to your problem.
'typedef std::list<type> SOCKLIST;'
|
|
|
|
|
Yeah the forum ate my code. The type was, let's try to do this explicitly,
typedef std::list<Socket *> SOCKLIST;
but I fixed the problem, so it's OK. Thanks for the feedback!

Hi all,
I'd like to create the flat toolbar button effect using VC 5, can it be done? I know that this is a feature that wasn't added until VC 6, but doesn't the toolbar class just call COMMCTRL32.DLL anyway?
Under C++ Builder I recall being able to set new styles by overriding the window creation process, I assume this can be done with VC 5, I'm just not sure where? Also, VC 5 doesn't have the necessary defines, so I'd need the numbers as well. I think the necessary defines are CBRS_GRIPPER and TBSTYLE_FLAT, which I'd insert into the SetBarState(...) during creation of my FrameWnd???
Thanks

How can my program work in another computer without VC++ installed?
When i copy all the files from DEBUG directory and try to run the program in another computer, it always said missing some DLL files.......
How can I solve this problem??? I don't want to copy the DLL files everytime....
Thanks

go to Project / Settings / General / MFC and choose "Use MFC in a static library".
this will link all of the MFC and C-runtime stuff into your app so you won't have to distribute the DLLs.

I did!!!!! I did set it using static library....but still doesn't work...
Also, one of my another program works succesfully in another computer, but it cannot show some dialog box!!!!! What happened??? What is the procedure my copying the program to another computer??????

Which DLLs are reported as missing? If linking statically with the CRT doesn't solve it, you'll need to copy those DLLs over along with your app.

Sometimes, arming yourself with a big pointy stake just won't do you any good.

|
|
|
|
For example, MSVCRTD.DLL, MFC42D.DLL....
|
|
|
|
|
these are the MFC debug DLLs.
if your program is asking for these, then it looks like your program (or something it's linking with) is not statically linking to MFC.

Try: Project>Settings and then select "Release" from the drop down combo box and again use the MFC in a statically linked library, this will make ur .exe file smaller. To compile goto Build>Batch build and check "Release" and click build. then goto the Release directory in your project and try that .exe file. Good luck, hope this helps....

First if you are going to distribute you application you need to compile it in release mode. The errors you are getting are because the debug version of those dlls are not on the target system, which they would not be if it is not a development machine.
Whether you statically link or dynamically link is up to you, however consider that statically linking increases the size of your redistributable.
If you are distributing this application the wrong thing to do is copy copy a folder, i.e. the debug folder. What you need to do is use an installation program such as Installshield or Wise. These tools help with such issues as registering COM components and ensuring the proper version of the required dlls on in place.
Second, ignore the advise given to you already.

I get an error "Unhandled exception at address 0x00000005" in my code. This function has already been called once when my program calls it again, and works fine the first time. The error line is on a simple assignment line:
iBytesReceived = 0;
Using the debugger to check the variable right before the assignment yields "CXX0069: Error: expression cannot be evaluated"
MSDN says this about error CXX0069:
"variable needs stack frame
The expression evaluator cannot evaluate the variable because it does not occur in a stack frame. This may be caused by variables declared as part of an inline function."
So, what the heck does all this crap mean

Look at 'this', and see if it is NULL. It could be that you've tried to call a method in a pointer to a class that is NULL.

Hi,
I've developed a program that can display an array(16 elements) in graphic mode (just liked plotting a graph). The value of this array can be changed anytime, so I set a loop to keep checking the array and update the display. In this loop, I have to do some sorting, so there are so many for loops and if loop. These loops cause the display very very very very slow. However, these loops must be exist... how can i improve it?????
|
|
|
|
|
I'm no expert, but maybe if the sorting had its own thread it would solve your problem.
|
|
|
|
|
Yes using a seperate thread would give the appearance that the draw was being done more quickly. A means to check if updating is required before doing any sorting or drawing would also help.
Make sure you understand the issues involved with multi-threading before you attempt it.
These are professionals, please don't try this at home.;)
