I know that, but I was desperate enough to even try that.

I have got the following function, that formats the string with dynamic params, but here i am using MFC CString class and its method AppendFormatV
void FormatStringWithDynamicParams(LPCTSTR lpszFormat, ...)<br />
{<br />
<br />
va_list args;<br />
va_start(args, lpszFormat);<br />
<br />
CString strMsg;<br />
strMsg.AppendFormatV(lpszFormat, args);<br />
}<br />
<br />
CString strTest="Test";<br />
DWORD dwTest=233;<br />
FormatStringWithDynamicParams("Here is one dynamic param :%s ",strTest);<br />
FormatStringWithDynamicParams("Here are 2 dynamic params:%s:%d ",strTest,dwTest);
Here it is working for both of the function calls, but i want above feature, without using MFC, i.e not using CString class, can any one help me in that.
Warm Regards,
Mushq

Are you looking for vsprintf()?

Thanks Paresh.
But I want to know which API system uses to create a folder on vista. It is not CreateDirectory.

It's not CreateDirectory(), I have tried using API Monitor, may be some shell's API.
Anyway thanks!

You didn't read the documentation. CreateDirectory() is available for use on Vista. Have you taken into consideration that you are using it incorrectly, or that perhaps it is a permission-related issue?

eventually the Shell will call it.

( keep in mind I don't have Vista )
SHCreateDirectory() ?

Hi everybody,
since a several time i have great troubles with the DebugHeap.
I put for example 2x new CStatic variables at my view,
so they are at the end of the class declaration :
class MyView
{
.......
.....
...
......
....
CStatic a;
CStatic b;
};
Each time i destoy the view he has a debug heap error. Not at the destructor from the view but at
the internal destrucor of the real Object ( CObject i think )
then, i put the two CStatic's to the place where i have already declared another CStatic's and
miracle, no errors.
I had the same heap error at different views.
Now, the same case. I open a view in a frame (a), which opens a new Frame(B) and View and minimizes his-self
So i have a frame which is in normal state and another in minimized state.
Then i close the whole application : Heap Error of a CString in a Toolbar-Object
If A has the focus and B is still opened -> Error
If B has the focus and A is still opened -> No Error
I close B and A is still open -> No Error
I close A and B is still open -> No Error
I close A and B -> No Error
The error occurs after the ExitInstance of the Main-Application-Thread.
The Heap would be modified after freed 
Does anyone has an idea ?

If you are seeing a heap error with a CString, you need to make sure you are not using the CString incorrectly, like by passing it, or any pointers returned by it, to any functions that may write into it. Storing any pointers returned by a CString object
You could also have some memory "near" the CString memory that is being overrun/underrun and is damaging it memory. What is the exact error you are getting? Are you sure it is freed memory being used again?

It crashed during the destruction of a Toolbar, now i removed the Toolbar which produced this error.
And now it crashes in the same way, but much earlier, at the destruction of the frame which has the focus.
But also with the message "HEAP : Free Heap Block ... modified at .... after it was freed"
The error is produces in this stack-order :
scalar deleting destructor() -> CObject:operator delete() -> dbg_free
The destructor of the Frame is already finished ( verified with a DebugMessageString )
I have no ideas

Look for places where you might be storing a pointer value returned by CString objects - this is generally a good sign that you are either using a CString incorrectly, or should not be using one in the first place.
Things to look for:
(LPTSTR)(LPCTSTR)sSomeCString
sSomeCString.GetBuffer(...)

mmh.
At the beginning i saw that it was an error with the CString ( it happens after the CString Destruktor )
But now, with the "new" error at the CObject-Destruktor of the Frame with the focus, i don't have an error at a CString. The two only CString's are destructed correctly.
if i have a
char temp[50];
and a CString str = "lalalala";
how can i put the data of str into temp;
since now i made it via strcpy(temp,str.GetBuffer());
Apart of an overflow if temp is too small i can't see a problem in this case, or ?
Thanks

Why you needed this ?
Doesn't CString's operator LPCTSTR suffice ?
|

i remake an existing DOS-Application into a MFC-FrontEnd.
I need to use the existing functions, which are working with char*
|

You can just do:
strcpy(temp,str); But you should really be using n-versions of the string functions to make sure you do not overrun the temp buffer.
Note that a CString can be used in place of a const char * or LPCSTR/LPCTSTR, so you generally do not need to copy its contents to a char buffer unless the string data is being used in a non-const fashion.
Carefully examine any places where you are using CString::GetBuffer(...) - it usually means that something strange is going on. If you have to use CString::GetBuffer(...), you likely should not be using a CString in that situation (not to mention that calls to it should be wrapped in a try/catch for exception handling).

I found the error:
Frame A is a Search Window whoch opens the Frame B, a Detail-Window.
If i search a customer and hit enter-key the customer will be opened into a new Tab of
Frame B ( B will be created if not already exists ) and A minimizes
If i close all Tabs from B, B minimizes and A appears(restore)
So i need a pointer from A to B and B to A.
At the destructor of B i test of A is still present, if yes, his pointer to B will be NULL, because
B is beeing destroyed and A does no more have a relation to B.
The test, if A is still present, was not good enough, i called the Frame A, then his View ( which was already deleted ) and modified his pointer to B ( to NULL )
In that way i get the "modified after freed"

Hi Friends,
While i was trying to install VS2005, I got so many errors. especially errors related to "cab" files.
Here i just want to share how i fixed them.
Hoping this will be helpful to the people,who come across this kind of errors.
Steps :
______
1)Remove the network cable from your machine.
2)Uninstall the "Anti-Virus" program.I don't know how it will effect the installation.
3)It is preferred to copy the CD contents to a sample folder in the C drive and then install the setup.
4)Whenever you get "cab" file corruption error.Try to copy the file to some other location and again try to replace the original file with the copied file.(though the two files are same). and then click on retry..(It worked for me.)
I am not hundred percent sure,whether all these things are going to work.But it worked for me.
Comments welcome.
Thanks.
