thanks, i don't think my c++ is the problem, i must have the wrong hwnd or something, when the window's fullscreen i can get the width and height but when it's windowed, the rect appears with uninitialized values. it's game maker i'm trying to get the client rectangle for so there's probably someone in the gm forums that knows what's up

So what is GetWindowInfo() returning?

found the problem Smile | :)

, i was getting the wrong window handle after all. i thought the program just used one window but the handle changes when fullscreen / 3d mode is toggled or something like that so i'm required to pass the new handle to the dll. i was getting uninitialized values in the window info stucture when i changed between windowed and fullscreen mode. now it's working ok

thanks

Hi,

One way is to accept the string(s) as command line parameter(s) and then use GetCommandLine()[^] to retrieve the command line parameters and then process them.

Problems running code on XP x64

Hello,

I'm pulling my hair out trying to figure this one out. I received some native C++ code from a colleague and compiled it under VS2005. I used the Win32 configuration,and it works fine on Windows 32-bit. However, this same app fails on x64 ("Application is not a valid format"). SO I tried compiling for x64 and running it, and it fails on BOTH 32-bit and 64-bit! I following Microsoft's directions here[^], but I still get the same error. I have the 64-bit tools installed, so what am I missing? Do I have to compile this from the command line instead of from the IDE?

Any suggestions are appreciated.

Thanks,

Dybs

Any 32-bit app should work on 64-bit windows without any changes.

Exactly what goes wrong when you run the 32-bit version of the app on x64?

That's what I thought. It's just a simple stand-alone console app. When I try to run it, I get the error message The application is not a valid format or something to that effect. I don't remember the exact wording right now, but I can post it when I get to work in the morning.

Richard,

The exact error message I get is

"This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem."

I can't really "reinstall" it since it's a standalone exe. Like you said, I thought any 32-bit program would at least run on a 64-bit system. Any ideas?

Thanks,

Brandon

Hi Brandon,

That error usually means that the Side-by-Side (SxS) runtimes have not been installed.

Make sure you install the runtime libraries for your application.

If you go to your "redist" folder inside your Visual Studio tree, you'll find the redistributables for C++ and MFC. Install those onto the target machine, and it should work.

Do you know from which method it is crashing? Does your methods have exception handlers?

One lazy way->

try{
int nLine = 1;
//possible crashing code
nLine = 2;
//.
nLine=3;
//.
nLine=4;
//.
}
catch(...)
{
//log/messagebox nLine
}

converting any base to decimal base 10

19-Nov-09 13:36

In short : I'm having trouble trying to figure out to convert any base number{2-36} to base 10 in C++.

Really, I'm supposed to design a program that can take in any InBase number(2-36) and convert it to any OutBase(2-26) by use of a stack.
As a solution and probably a inefficient one, I thought I would convert the InBase first to a base 10 number and then reconvert to whatever chosen OutBase.

Psuedo or the actual code is much appreciated but really, I need an good explanation on how I could implement this way of conversion.

I'm using Visual c++ 2008 express edition to code the program.

Thanks in advance.

The formula for converting to base 10 is (base^n * dn) + ... + (base^2 * d2) + (base^1 * d1) + (base^0 * d0) read as base to the power n into dn
where d0 is the left most digit and dn is the right most digit and base is the base value using which the number is currently encoded.

Once you get the base 10 value you can convert it to any other base between 2 - 36 using the _itoa_s.

I can't see any examples of this function. I was hoping if answered the following issue below...

I have been asked to have arrow keys work in the microsoft C++ Ribbon bar like they do in Microsoft Word 2007.
Press F10 in Microsoft Office and then hit the arrow keys and it will move the user across the categories. When I do this in the microsoft demo, it doesn't do this.

CRichTextCtrl maintaining paragraph justification

Hi,

I'm reading a file straight in to a CRichEditCtrl, butI am not getting any justification maintained.
The rtf file has been created in Microsoft Word, and is fully justified (to fill the screen etc), but when I read the file in to my control each paragraph just appears as a single line.

I have tried using SetParaFormat but it seems to make no difference.

My PARAFORMAT2 is configured as below

<pre>
PARAFORMAT2 pf;

// Modify the paragraph format so that the text is centered.
pf.cbSize = sizeof(PARAFORMAT);
pf.dwMask = PFM_ALIGNMENT;
pf.wAlignment = PFA_JUSTIFY;
BOOL bOK = m_rtfControl.SetParaFormat(pf);

</pre>

Any help on getting over this hurdel would be much appreciated.

Did you enable the advanced typography for your CRichEditCtrl by sending the EM_SETTYPOGRAPHYOPTIONS[^] message?

If not the control will not maintain the paragraph justification.
You can enable the advanced typography like that:

::SendMessage(hWndEdit, EM_SETTYPOGRAPHYOPTIONS, TO_ADVANCEDTYPOGRAPHY, TO_ADVANCEDTYPOGRAPHY);

Thanks for the reply Nuri,

I have tried to implement that in my OnInitDialog, along with setting PARAFORMAT2 etc.
The hwndEdit you mention is, I assume, m_hWnd of the edit control, e.g. MyRichEditCtrl.m_hWnd?

I have added richedit.h to my project, in fact I have tried pretty much all that I read on various sites, but with no joy.

Do you have any further suggestions?

My code now looks like

<pre>
//open the fiel that contains the commissioning information
     CStdioFile cFile(TEXT("RES\\Message.rtf"), CFile::modeRead);

     //ensure a blank canvas
     m_rtfCtrl.Clear();

     //enable advanced typography
     ::SendMessage(m_rtfCtrl.m_hWnd, EM_SETTYPOGRAPHYOPTIONS, TO_ADVANCEDTYPOGRAPHY, TO_ADVANCEDTYPOGRAPHY);

     PARAFORMAT2 pf;

     // Modify the paragraph format so that the text is centered.
     pf.cbSize = sizeof(PARAFORMAT);
     pf.dwMask = PFM_ALIGNMENT;
     pf.wAlignment = PFA_JUSTIFY;
     BOOL bOK = m_rtfCtrl.SetParaFormat(pf);

     EDITSTREAM es;

     //read the data by setting up the callback
     es.dwCookie = (DWORD) &cFile;
     es.pfnCallback = MyStreamInCallback;
     m_rtfCtrl.StreamIn(SF_RTF, es);
</pre>

Yes, it is the m_hWnd of your edit control.

This is from your code:

PARAFORMAT2 pf; // !!! You use PARAFORMAT2

// !!! But here you use the size of PARAFORMAT. Change the PARAFORMAT to PARAFORMAT2
pf.cbSize = sizeof(PARAFORMAT); 

pf.dwMask = PFM_ALIGNMENT;
pf.wAlignment = PFA_JUSTIFY;
BOOL bOK = m_rtfCtrl.SetParaFormat(pf);

Try with this change. If this don't solve your problem, then you have to paste your MyStreamInCallback function because there are some tricks about this callback for UNICODE builds. Smile | :)

Hi Nuri,

Your initial help was spot on, it was a different issue causing the problem.
The Auto HScroll was set, and as soon as I unset that (FALSE), everything sparked in to life.
I dont have any need for the SetParaFormat now, so my other mistake can now be deleted anyway.

Many thanks for your help
