Hi, I'm using Visual c++ and I've done a program where I've defined my own file format. I would like to be able to create file associations with my program with these type of files...lets say *.qif .
Anyone has any ideas how I could do this, so that when I click on a *.qif file, my program would load and on startup would load the specific *.qif file?
I'm not using a SDI or MDI. The program is dialog based, and the file format was generated from an edit box.
Thanks for any suggestions..

You can do the same thing that an SDI or MDI application does, call RegisterShellFileTypes().

You need to write appropriate registry entries into the registry.
In the HKEY_CLASSES_ROOT, add the appropriate data excluding quotes
1) Add a key called ".qif"
2) Under .qif set the (Default) string value to "QifFile"
3) Add a key called "QifFile"
4) Under QifFile add a key called "shell"
5) Under shell add a key called "open"
6) Under open add a key called "command"
7) Under command set the (Default) string value to the commandline parameters of your application.
And basically thats that.

For #1 - Its very strange, verify if the user that you are using to start the windows service have the privilegies. Show your code. 
#2 - Try to use Hook Mechanism. The KeyBD_Event does not work with Windows Service, because The windows Service does not get messages from KeyBoard. You should use Hook ... Look for Hook in Code Project, that you will find your information.

What user account is the service running under? It seems that you either need to alter the account that the service is running under or you need to alter the account privileges.

I try to create a dynamic char-array and then copy a certain number of chars from another string to it:
<br />
char *tempLabel = new char[labelLen];
strncpy(tempLabel, label, labelLen);
When I step through the code the variables contains:
After line 1:
label = "resolutionXììììììììì....aso" (is an [128]-array)
tempLabel = "ìììììììììììýýýý" (as you see, 4 chars too much)
labelLen= 11;
After line 2:
label = "resolutionXììììììììì....aso"
tempLabel = "resolutionXýýýý" (Still too big!)
labelLen= 11;
Why??? I don't want those 'ý'-s, what's wrong? Does anyone have a clue?

|
|
|

if(labelLen>0)
{
char *tempLabel = new char[labelLen+1]; //Line 1 make room for \0
strncpy(tempLabel, label, labelLen); //Line 2
}
Papa
while (TRUE)
Papa.WillLove ( Bebe ) ;
|
|
|
|
|
Try this:
char *tempLabel = new char[labelLen]; //your Line 1
memset(tempLabel, (int)'\0', labelLen);
strcpy(tempLabel, label); //Line 2

This is exactly how buffer overruns are exploited (i.e., using strcpy).

I would say how they are caused not exploited.

Fair enough, but the point remains.

Thanks guys!
Really stupid of me to forget about that '\0'. I should remember that by now...

BOOL CBeginDoc::OnNewDocument()
{
if (!CDocument::OnNewDocument())
return FALSE;
// TODO: add reinitialization code here
// (SDI documents will reuse this document)
m_pScene = new CScene( AfxGetMainWnd()->m_hWnd );
return TRUE;
}
Program exit when execute AfxGetMainWnd(),what's wrong!

When your application starts, the main window isn't already created when OnNewDocument is called the first time. Try this and it will work:
BOOL CBeginDoc::OnNewDocument()
{
if (!CDocument::OnNewDocument())
return FALSE;
// TODO: add reinitialization code here
// (SDI documents will reuse this document)
if(AfxGetApp()->m_pMainWnd!=0L)
{
m_pScene = new CScene( AfxGetMainWnd()->m_hWnd );
}
return TRUE;
}
Hope this helps

Hi there,
Because the MainFrame isn't the active window yet - AfxGetMainWnd will return a NULL pointer in which you use without testing.
Why is it that you are initialising your object with the Main window anyway? The object can use the AfxGetMainWnd when it needs access without you setting the value in the constructor. If you are setting the object to use a particular HWND, then set it to NULL in the constructor, then when the object needs the HWND test if it's NULL - if yes then perform AfxGetMainWnd otherwise use the HWND it has.
Hope this helps,
Andy

I have bought some ActiveX controls from Global Majic about 6 months ago (only get 3 months support), but when I deploy my application I get an Assertion error (its build for Release).
I dont see in the deployment (Visual Studio .Net 2002) how the OC are deployed.
Do I need to register them on the target PC?
Or is the Assertion proble a Red Herring?
|
|
|
|
|
Normally you just have to copy the .ocx file on the target computer and register it using regsvr32.exe.
|

|

OK, thanks. I just wondered if the deployment process would do this.

I want develop Firewall But how to use Windows Platform SDK. I want Help is it . Your can't explaint or detail about web to detail about Windows Platform SDK . Where i can find it .
|

The platform SDK ships with your Visual Studio installation, you don´t need to install it.
You can download the latest version from MS or install from an MSDN CD, it can be necessary if you need to use really new features, or uncommon APIs that don´t ships with VStudio, but usually it is the case for less than 1% of the programs you need to develop.
