Arrrggghh!
I'm having trouble with InsertItem(), for an CTreeCtrl object. The following gives me an Assertion Error, twice on each iteration of the for loop. 
CdlgABC* dlgABC = new CdlgABC(this);
for(int j=0; j<i; j++)
dlgABC->m_tree.InsertItem(dlgABC->m_strArray.GetAt(j), TVI_ROOT, TVI_SORT);
dlgABC.DoModal();
Any clues as to what to check out, would be greatly appreciated.
Thanks!!

Before DoModal your CTreeCtrl isn't associated with Win32 HWND. It can't do anything, especially invoke InsertItem. Put your code in CYourDlg::OnInitDialog.

Hi everyone,
Does anybody know of an easy way to change the dropdown arrow on a Combobox to a user-defined icon? I guess it will need some sort of owner-drawn implementation? Are there any examples that anyone knows of?
Thanks in advance for your help...

I run the console application (ie. ipconfig) from another process and need to read ipconfig's text output.
Is it possible or not?
Thanks,
Marek.

Hi, I have created an MDI using CFormView. I have 2 forms. CMyProjView is the 1st form containing user inputs. The second form is activated using a button handler.
How to access data stored in CMyProjDoc from the second form?
I tried this in OnInitialUpdate() of CForm2
CMyProjDoc * pDoc = (CMyProjDoc*) GetDocument();
m_Variable = pDoc->data[i];
m_EditBox.Format("%.2f",m_Variable);
but I get an Assertion failure.
Any suggestions?
Thanks

Where exactly you're getting assertion failure?

The form is created in CMyProjApp::InitInstance and a call to OnInitialUpdate() is made.
The failure occurs when I execute the project; i.e. immediately
|
|

|

Look at the call stack and check where exactly are you getting the assert.

It's said that "The system associates a window station with a process when the process is created" in MSDN.
but in what case does a process not associate a window station?
hi
|
|
|
|

From MSDN:
"A window station is a secure object that contains a clipboard, a set of global atoms and a group of desktop objects. The interactive window station assigned to the logon session of the interactive user also contains the keyboard, mouse, and display device. The interactive window station is visible to the user and can receive input from the user. All other window stations are noninteractive, which means that they cannot be made visible to the user, and cannot receive user input"

AFAIR, service processes under NT 3.5 had no winstation, but they've changed in NT 4.0. Why are you asking?

A window station in the MS terminology is a virtual window station in which processes are run in a separate address space, and by the way are not visible to your current session (even in the task manager).
In fact MS introduced window stations along with desktops. The system can have many window stations. Each window stations can have many desktops.
The interactive window station,  yours , is window station named "winsta0" with default desktop named "default".
Wat are window stations for ? for instance to circumvant current NT limits such like the total amount of GDI objects per session.
If you need to know more about this, do a search with "winsta0",
And I swallow a small raisin.

Processes are executed in separate address spaces, with winstations or not.

You're right, but this precision is unnecessary,

I want to use file mapping and this is my code:
<br />
HANDLE hSearchedFile,hMap;<br />
LPVOID pFile,charSearch;<br />
LPCTSTR fName = strName.GetBuffer();<br />
<br />
hSearchedFile = CreateFile(fName,GENERIC_READ,0,<br />
NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);<br />
<br />
hMap = CreateFileMapping(hSearchedFile,NULL,PAGE_READONLY,0,0,NULL);<br />
<br />
if(hMap==NULL)<br />
AfxMessageBox("Could not create file-mapping object");<br />
<br />
pFile = MapViewOfFile(hMap,FILE_MAP_READ,20,0,0);<br />
<br />
<br />
if(pFile==NULL)<br />
AfxMessageBox("Could not map view of file.");<br />
hSearchedFile is always 0xffffffff but hMap and pFile are always NULL.I don't know whats the problem with my code.Any idea?

CreateFile returns INVALID_HANDLE_VALUE. Probably file doesn't exist. Check GetLastError for more info.

Hello
I have a txt file I need to insert a string into at the start of. If the file does not exist I need to create it, and insert the line of txt.
What is the most elegant way of doing this using C++? An ugly ways seems to be to check if the file exists. If it doesn't, create, write and go home. If it does then I must make a copy of it, overwrite the original with my new line of txt, and then append the contents of my copy into this. This seems a real hack, and I am looking for a nicer way? Perhaps there is some nice strstream method?
Looking forward to replies...
