i have a simple dialog project with a button and multiline edit control.
button click runs a worker thread which updates edit control data.
and i have also mapped the ON_WM_CTLCOLOR() to change colors of controls
and dialog.
if i run the thread 2-3 times my program crashes.but if i comment all
my coloring code from ON_WM_CTLCOLOR() it runs fine without any problem..

You should not update UI from workerthread.

c1010070:failed to load and parse the manifest

Hi,

I'm trying to create a manifest file in order to set the setting for UAC in Vista.
I already refer to msdn document. If I want to develop codes that need to be run in Vista and XP, I need to use the notes for-Building and Embedding a Manisfest with Microsoft Visual Studio 2005 for Windows Xp and Windows Vista Applications.

This is my manifest file.

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestversion="1.0">
<ms_asmv2:trustinfo xmlns:ms_asmv2="urn:schemas-microsoft-com:asm.v2">
<ms_asmv2:security>
<ms_asmv2:requestedprivileges>
<ms_asmv2:requestedexecutionlevel level="asInvoker">

But when I run, I got this error message:
general error c1010070:failed to load and parse the manifest.

FYI, I already go to Project Properties-Linker-Generate Manifest - NO.
Beside that, I also change at Project Properties-Manifest Tool-Input and Output-Additional Manifest File (i type the manifest file name).

Any ideas about this?

Thanks

My program is only 3XX KBytes size.
It start very fast (1 to 2sec) in XP, but very slow (about 13sec) in Vista. What's problem? How to make it faster?
Please help!!

At this point, it could be most anything. Do all of your programs behave in this fashion? Are the slow ones connecting to a database or a remote machine? Could it be a security issue?

I'm not sure what 'RAND_MAX' is, but other than that, the conversion produced by C++ to Java Converter follows (including a helper class that the converter outputs to help simulate C++ random number functionality in Java):

import java.util.*;

//C++ TO JAVA CONVERTER NOTE: The following #define macro was replaced in-line:
//#define rand01 (0.9999999*double(rand())/RAND_MAX)

private void test()
{
r = (int)(Math.floor(N*(0.9999999 *(double)(RandomNumbers.nextNumber())/RAND_MAX)));
}

Seed();

return r.nextInt();
}

{

Seed();

return r.nextInt(ceiling);
}

r = new Random();
}

{
r = new Random(seed);
}

Conv. VC++ 6.0 to VC++2008

I have been assigned the task of updating a Visual C++ 6 software package to Visual C++ 2008. VS2008 did a bang up job during the conversion, leaving but a couple of dozen items to repair my self. One in particular has me against the wall.

Here is the reported error;
error C2678: binary '||' : no operator found which takes a left-hand operand of type '_bstr_t' (or there is no acceptable conversion)

The line it refers to is;
ASSERT(m_bstrDataSource);

Here is the ASSERT definition in AFX.H;
#define ASSERT(f) DEBUG_ONLY((void) ((f) || !::AfxAssertFailedLine(THIS_FILE, __LINE__) || (AfxDebugBreak(), 0)))

I would greatly appreciate some guidance.

try ASSERT(NULL != m_bstrDataSource);

The ASSERT macro needs to passed a boolean expression so that (f) in the macro will evaluate to either true or false.

How to create a MFC Dll to use managed extensions??

materatsu17-Nov-08 8:53

Hi dudes!

I am currently facing this problem, i am creating a new MFC static Dll but when i add the CLR support i get weird errors like:
->Command line error D8016 : '/MTd' and '/clr' command-line options are incompatible cl
i "fixed" this by changing Runtime Library to '/MDd' option

And then it throws me:
->fatal error C1189: #error : Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version. Please #define _AFXDLL or do not use /MD[d] C:\Program Files\Microsoft Visual Studio 8\VC\atlmfc\include\afx.h 24
I change my Dll to MFC shared dll version

Next it compiles but it gives me this warnings:
->warning LNK4099: PDB 'mfcm80ud.i386.pdb' was not found with 'C:\Program Files\Microsoft Visual Studio 8\VC\atlmfc\lib\mfcm80ud.lib' or at 'c:\XXX\npwyncs_dll\debug\mfcm80ud.i386.pdb'; linking object as if no debug info

My question is what is the correct or best way of doing an MFC dll support CLR, cause i am not too comfortable doing all this ?

Thx

Dude! Since you asked for the "best" way, it's the same as always, reading the freaking documentation is the best way. See how simple it is to find?[^] Roll eyes | :rolleyes:

I'm working on a program that basically sits and acts as a system monitor. Two of the primary things that I want it to do are monitor system memory and display when the last time a virus scan was made. Any suggestions on how I might go about this?

Thanks in advance
