I have to convert a command to be sent to a piece of hardware from hex to char... i've done this in the following way and it works in vc++6 but not in vc++7 ?? it compiles fine in both but the command is different... anyone got any ideas why ??
CString csTrigger
csTrigger.Format("%c%c%c%c%c%c",0xFC,0x06,0xC3,0x00,0x04,0xD6);<br />
any ideas would be appreciated..
Regards

If I understood you correctly, you want to display the given hex digits as a string representation. If this is the case then you need to use the %X format.
<code>csTrigger.Format("%X%X%X%X%X%X",0xFC,0x06,0xC3,0x00,0x04,0xD6);
</code>
Why your sample code would change behaviour on VC6/7 I haven't got a clue!

Thanks for responding... i need to use the %c to build up a string of characters from the hex values. like i say it builds in both but the conversion is different... i have tried checking the char sets etc but cannot find what is wrong. if you build a very basic project in both and put the line of code in both and step thru it, if you check the contents of the string you will see the differnce ?????

I'm puzzled because I have tried it (on VC6 and VC7.1) and they both behave as expected (displays 'üÃ').
Remember that the character string you are trying to build consist of these ASCII value: 0xFC,0x06,0xC3,0x00,0x04,0xD6. This equates to:
ASCII: 252, 6, 195, 0, 4, 214
First off, all of these ascii values does not map to 'regular' characters. 0x6 and 0x4 are non printable characters, and 0 is the null terminating character, so your string will stop at 0x00, resulting in the three letter output I gave above.
Unless you've done something else in your code, this is how it should execute. What is the output on your VC6 compilation?

Hi all
I am using cr 10 for showing some reports saved as rpt files. I change the database connection at runtime.
Everything works fine.
But when the report window is opened (this is another window, a modelless) and if the export button is selected, my application remains running on the task manager.
And this happens only on widnows 2000.
All the Crystal report objects are made inside a function and shown on the OnInitDialog of the report window.
I included the craxdrt.h and created
FunctionCalledFromOnInitDailog()
{
IApplication app;
app.CreateDispatch(_T("CrystalRuntime.Application"),NULL)
//I do the rest of the things here, set the datasource of the viewer
//control etc
m_cysApp.DetachDispatch();
}
Any idea whats going on ?
Please help me.

Hi guys
I've developed a Doc-view app.
My documents have an extension (.mqw)
If I open my app and drag and drop a .mqw file inside it opens correctly.
If I use Open inside my app, the file opens correctly too.
But if I double click in a .mqw file my app give me an unhandled exception
I've already associated the .mqw files to my app.exe
What is the difference between these procedures to give me an error when I doubleclick my .mqw files?
Thanks in forwarding
Doc

I think that the differences are that you have not implemented the command-line option for the program. When you double-click the file windows does this:
exec <your program="">.exe <file_path>
implement a function that parses the commmand-line options ( remenber the argv and argc in int main(int argc, char* argv?)

Double click in Explorer uses DDE if your app is already running and you've registered your extension. Have a look at the DDE handler CDocManager::OnDDECommand() which will call your CYourApp::OpenDocumentFile( LPCTSTR lpszFileName ).

hello everybody,
i use the following code :
HICON hIcon = LoadIcon(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDI_PREVIEW));
CButton* pButton = (CButton*)GetDlgItem(IDC_PREVIEWFACT_BTN);
pButton->SendMessage(BM_SETIMAGE, (WPARAM)IMAGE_ICON, (LPARAM)hIcon);
this code is supposed to set the IDC_PREVIEWFACT_BTN button face with the IDI_PREVIEW icon.
the icon is 16x16 pixels, and the button is bigger (in pixels) than my icon (i cannot say how wuch, because the resource editor don't "speak" in pxls).
my problem is that the ison displays quite "well", except the fact that is is much bigger than the button (so truncated).
does anyone know how to display the icon to its real size ?
thanks in advance...

You may want to look into using CFormView, it's a view that's based on a dialog box.

You can try Sleep(1000);

Hello,
In my MDI application, i have two child windows and a child dialog Box. I can switch between any two child windows and i have event handler for toggling.
Following is the code-
BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
//..............
ON_COMMAND(IDM_TOGGLE_WINDOW, OnMenuToggleWindow)
//..............
END_MESSAGE_MAP()
void CMainFrame::OnMenuToggleWindow()
{
assert(isTerminalMode() || isDataMode()|| isFlightAnalysisMode());
CMainFrame::ActivateFrame(SW_SHOWMAXIMIZED);
::PostMessage(m_hWnd,SIZE_MAXIMIZED,0, 0);
if (isTerminalMode())// child window
//setDataMode();
setDataMode(); //child window
else if (isDataMode())
setFlightAnalysisMode(); //dialog Box (child)
else if (isFlightAnalysisMode())
setTerminalMode();
}
Now, all the windows are working properly but as soon as i switch to another window, everything stops working. I can still toggle windows, but
data doesn't get refreshed.
What should i do?

Hi, I asked earlier about some help with a problem I am having.
I have a dialog based application in which has a Browse for directory call. Thats fine, I have that implemented, when the user selects the folder they want my program to scan it returns the folders path as szFolder.
I have a list control, m_contentlist, which I want to display the contents of szFolder in (directory selected)
Can someone please post code rather than links? That would be very helpful.
Thankyou
Ashman

Here's a starting point:
CFileFind ff;
ff.FindFile(szFolder + ???);
while (...)
{
ff.FindNextFile();
}
