i've created a visual studio add in using the wizard.
i copied a method from other project (that i found here in code project) that retrieves the *.dsw file path.
here is the code:
CString CCommands::GetWorkspacePath()
{
CWinApp* pApp = AfxGetApp();
CString szWorkspace;
POSITION posdt = pApp->GetFirstDocTemplatePosition();
while (NULL != posdt)
{
CDocTemplate* pdt = pApp->GetNextDocTemplate(posdt);
if (0 == strcmp("CProjectWorkspaceDocTemplate",
pdt->GetRuntimeClass()->m_lpszClassName))
{
POSITION posdoc = pdt->GetFirstDocPosition();
if (NULL == posdoc)
break;
CDocument* pdoc = pdt->GetNextDoc(posdoc);
if (NULL == pdoc)
break;
szWorkspace = pdoc->GetPathName();
if (0 == szWorkspace.GetLength())
break;
}
}
return szWorkspace;
}
problem is that this line :
POSITION posdt = pApp->GetFirstDocTemplatePosition();
returns NULL for the postd. when i try this code in the other project it works ok
please, i already post this question before, and didn't get any reply
can any1 help me?
thanks in advanced

Ask not what your application can do for you,

you are getting Null value returned by
pApp->GetFirstDocTemplatePosition()
bcoz you are using the base class pointer, and the base class pointer in not aware your projects Doc Template positions. If you type cast it into your project's application class, it won't return null value;
CWinApp* pApp = AfxGetApp();
CString szWorkspace;
((MyPrjApp*)pApp)->GetFirstDocTemplatePosition();
never say die

thanks for the response, that didn't work!
here is what i wrote and i got still a null:
CWinApp* pApp = AfxGetApp();
CString szWorkspace;
POSITION posdt = ((CBackITUp_AddinApp*)pApp)->GetFirstDocTemplatePosition();
i even try the extern thing:
extern CBackITUp_AddinApp theApp;
.
.
POSITION posdt = theApp.GetFirstDocTemplatePosition();
that didn't work as well!!!
please please i need help
(try to create a new visual studio add in project in VC6, then try the lines above, you will get the same result.....i am doing something wrong, but i can't figure out what is wrong....
thanks again

CWinApp* pApp = AfxGetApp();CString szWorkspace;//POSITION posdt = pApp->GetFirstDocTemplatePosition();POSITION posdt = ((CBackITUp_AddinApp*)pApp)->GetFirstDocTemplatePosition();
this code runs well when i executed it in newly created project. i executed this code in CMainFrame class message handler function.
i suggest you to try this code in CMainFrame Class for testing purpose only
the problem could be in base class of CCommons class, you haven't mentioned anything about its base class.

thanks for reply.
As I mentioned before, I am using a visual studio add in project the objects:
1. CBackITUp_AddinApp - the application
2. CCommands - the commands object
3. CDSAddIn - the developer studio add in object
4. ICommands - the commands interface
as you can see i am not using CMainFrame.....
I think I know what my problem is. the method GetFirstDocTemplatePosition will work only on the dev studio exe (the application which runs the add in) and not on the add in itself....
therefor when i am using
CWinApp* pApp = AfxGetApp()
I am getting a pointer to the add in (dll) main application object and not the exe main application object.....
now can you help?
thanks again
Yaron

according to me, you can solve the problem by creating a DLL project which has a fuction MyFunc() returning application object's address. Include this Dll in your addin and call MyFunc().

Hey Guys,
Yesterday I recompiled an MFC application in Visual C++.NET which had previously been built using VC6. Aside from a few casting issues, the compile seemed to work OK. However, the app will not execute. When I execute the app, the error I get is 0xC0000005: Access violation. The problem is that this exception is thrown before my app even gets into WinMain. The stack trace when the exception is raised is:-
<br />
NTDLL.DLL!_RtlRaiseStatus@4() + 0x24 <br />
NTDLL.DLL!_LdrpInitialize@12() + 0x15276 <br />
NTDLL.DLL!_KiUserApcDispatcher@20() + 0x7
When I take a look in the output Window after execution I get.
First-chance exception at 0x77f92373 (NTDLL.DLL) in WMSClient.exe: 0xC0000005: Access violation writing location 0x00000010.<br />
First-chance exception at 0x7c59ba9d in WMSClient.exe: 0x000003E6: Invalid access to memory location.<br />
First-chance exception at 0x77f92373 (NTDLL.DLL) in WMSClient.exe: 0xC0000005: Access violation writing location 0x00000010.<br />
First-chance exception at 0x77fb17a4 (NTDLL.DLL) in WMSClient.exe: 0xC0000005: Access violation.<br />
Unhandled exception at 0x77fb17a4 (NTDLL.DLL) in WMSClient.exe: 0xC0000005: Access violation.<br />
The program '[1968] WMSClient.exe: Native' has exited with code 128 (0x80).
At first I thought it was maybe caused by one of the global variables causing problems but most of them are basic types. Those which are classes, I put a breakpoint in the constructor but it never gets called.
Can anyone suggest anything else to look at?
Cheers
James

Hi !
In my application, I had to test many strings and (as the keyword 'case' is not usable for strings) I did something like this :
if (MyString==THIS_STRING)
{
}
else if (MyString==THAT_STRING)
{
}
else if (MyString==ANOTHER_STRING)
{
...
...
...
else
{
}
The problem is that I have to compare my string with more than 128 possible strings, and I discovered this morning that the compiler (Visual C++ 6) is not able to cope with more than 128 if's !!!!
Any idea on what would be a nice workaround for this limitation ?
Thanks !
Jerome

You could nest your Ifs, based in the first letter, then check for the second (and third...) letter in lower levels.
This way you can circumvent the limitation.
Who is 'General Failure'? And why is he reading my harddisk?!?

It is the most simplest thing to do in programming live,
here it goes, create an array of all the strings taht you want to compare with,
then in a loop compare with each string and do appropriate action.(you can build your logic around this)

How about switch... case... statement?
Although to be honest I like the idea of strings' array better. Unfortunately, it's not mine.  .

Where to get "sys/ioctl.h"???
Thank you!!!
Rap off for you,for me,for our human.
|
|
|
|
|
It won't matter whether you get it or not, unless you deleted it by accident. That's because the header files contain only declarations of functions, not their implementation.
I think sys/ioctl.h is a *nix header, if you're on windows you have little chance to compile the program (without many modifications to the code).

I have to develop a multithread application.
My problem is to wait the closure of all threads
when I close my application.
I have seen that WaitForSingleObject can be used
also for threads ? Is it possible that, suppling
the thread handle to this function I can solve my
problem ?
In another way I have used an event set by the thread
when it is going to exit (the application waits for
this event after having wake up the thread) but this
solution causes a application blocking (deadlock).
Can someone help me ???
Thanks a lot !!!

afaik you can use the WaitForSingleObject / WaitForMultipleObjects to wait on thread handle for it's closure.

Hello-
I would like to build an interface with dockable pieces to it. These pieces probably most closely resemble a dialog box. That is, they have several controls as components.
I would like to construct the pieces by code -- without the dialog editor. I'm quite new to all of this, so I may be attacking this the wrong way, but I am looking at the CDialogBar class which is at least a start for dockable dialogs, but doesn't allow creation without a resource ID.
Is there a better approach? How can I create a CDialogBar without a resource ID?
