Could you please stop spamming the forum ? You posted this 1/2 hour ago. And, as a side note, your question is not clear at all. May I suggest you read the posting guidelines before posting again (this is the message at the top of this forum).

It would be really helpful if you could provide some sort of screen shot exhibiting the problem.

Converto long to char []

Hello!

I am using a C51 compiler for a microcontroller (so not visual studio)

I am trying to convert a long int variable to a char*, using C-specific functions (no atoi and the rest)

long Value="1234";
char String[15];
sprintf(String,"%d",Value);

This puts in "String" the value "0".

If I make Value of type integer, it works. What seems to be the problem ?
Are there any (other) functions to help me do this ?

Where can I find the source code for ltoa and the family, to declare it ?

Thanks,
Shpid3r

try:

sprintf(String,"%ld",Value);

(that's a lowercase "L" - for "long")

atoi and the rest are all ANSI C functions.

How does this even compile ? You are trying to assign a string (yes, "1234" is actually a string) to a long. You should at least get a warning here...
Try without the double quotes:

long Value = 1234;

:ashamed of myself: $Shucks | :-\$
I didn`t paste the code, just reproduced it here, and in the hurry I put the quotes...
Of course it won`t compile with them Smile | :)

Great, %ld" works!
Thanks! I spent the last 3h trying to figure this out ... I should have asked sooner!

Just FYI - I'm guessing that (unlike VC++), the C51 compiler has 16-bit ints, which are smaller than longs? And that the C51 is a big-endian chip? WHich would explain the zero result.

COM Object Released But DLL Still In Memory

Hi,

I have a program that uses a COM object. At somepoint I try to release the object. After I do the release process, I can see using Process Explorer that the ActiveX DLL is still in memory.

My code is below. Am I doing something wrong? Why is the DLL still in memory?
ComReleaseTest.DLL is a test VB ActiveX DLL I wrote to debug this problem. It does nothing - all it has is one test sub which I am not even calling.

<br />
#include "stdafx.h"<br />
<br />
#import "..\ProductTree\winpos\drv32\ComReleaseTest.dll" no_namespace<br />
<br />
_CComReleaseTestPtr m_Srv;<br />
<br />
int Close();<br />
void ReleaseObject();<br />
<br />
int main(int argc, char* argv[])<br />
{<br />
	HRESULT hResult;<br />
<br />
	try<br />
	{	<br />
		if ( TRUE )<br />
		{<br />
			hResult = CoInitialize( NULL );<br />
<br />
			if ( hResult != S_OK )<br />
			{<br />
				return 1;<br />
			}<br />
		}<br />
<br />
		HRESULT hr = m_Srv.CreateInstance(__uuidof( CComReleaseTest ), NULL, CLSCTX_ALL);<br />
		if (FAILED(hr))<br />
			_com_issue_error(hr);<br />
    }<br />
	catch(_com_error& e)<br />
	{<br />
		return (1);<br />
    }<br />
<br />
	Close();<br />
<br />
	return (0);<br />
<br />
}<br />
<br />
int Close()<br />
{<br />
	long Result = 0;<br />
<br />
	if ( m_Srv != NULL )<br />
    {<br />
		TRY<br />
		{<br />
			ReleaseObject();<br />
		}<br />
		CATCH_ALL(e)<br />
		{<br />
			TCHAR sError[255];<br />
			e->GetErrorMessage(sError,255);<br />
		}<br />
		END_CATCH_ALL<br />
	}<br />
<br />
	return ( (short)Result );<br />
}<br />
<br />
<br />
<br />
void ReleaseObject()<br />
{<br />
<br />
	// Disconnect from VB ActiveX<br />
	try<br />
	{<br />
		m_Srv.Release();<br />
	}<br />
	catch(_com_error& e)<br />
	{<br />
	   //<br />
	}<br />
<br />
	free(m_Srv);<br />
	m_Srv.Detach();<br />
	<br />
<br />
	m_Srv = NULL;<br />
<br />
}<br />
<br />
<br />

The reason I am trying to track this is that I have anotehr program that at somepoint calls an InstallShield 5.5 setup. This setup.exe hangs at 99% and I found that if my program does not call a certain ActiveX then there is no problem with the setup.exe. So I am trying to release that ActiveX before calling setup.exe, but the COM DLL just stays in memory!

The DLL won't get unloaded just because you've disposed of all the objects you got from it. The DLL stays loaded in case you want to create more objects.

You could try using CoFreeUnusedLibraries[^] to unload the DLL (but be aware that CoFreeUnusedLibraries will only work instantly in single-threaded apartments[^].

Hi Friends,

I need to add a new item into the context menu we see while we right click on a control panel item and show a message box when user clicks on my item.I just want to display the name of the item on which the user right - clicked in the message box.

Any ideas?

Thanks and regards,
J

All control panel items are actually DLL files that end with a .CPL extension.
To add a menu item to its context menu, you need to create a shell extension.
Look at this tutorial here - The Complete Idiot's Guide to Writing Shell Extensions - Part I[^]
