I'll quote here the e-mail you sent me:
wanthelp wrote:
I got the source code from Internet and used command nmake to build the library. The source code is programmed by c, so I think there is no project setting. Therefore, I can only change the setting of GATest project as you mentioned -- changing /MDd to /MTd, but it still does not work 
I will appreciate you can give me more instruction about it.
Best regards
I will appreciate if you post this kind of messages to the forum, which is where they belong, instead of directly e-mailing me. I'll answer it if I can, or anybody else may offer help too. Unless there's something strictly personal in your message, or I ask for it, a direct e-mail is not appropriate.
Now, to your problem. If you are using nmake to build the library, the project is the makefile being passed to nmake, and the project settings are the contents of that makefile. Locate the makefile, and look for any /MTd or /MDd in it.
BTW, which library is that you are trying to use? Maybe there are some online instructions or user forum where you can get more help?

Check the include files may be coming in loop like :-
//file b.h
#include "a.h"
//file c.h
#include "a.h"
#include "d.h"
//file e.h
#include "b.h"
#include "b.h"
This may reason for this LNK2005.
Remove this.
Check for Include files order in Directory tab from options.

How come? Include directives are processed at compilation time. LNKnnnn is a linker error...

How do you check if a check box has been checked?
I created a check box named IDC_checkbox and assigned a member variable of type Value named m_checkBox.
|
|
|
|
|
There's a member method called GetCheck. It returns a BOOL, which is an int, 0 is not checked.

If you used Class Wizard and added a variable of type Value, it must have defined it as BOOL.
When you want to check the state of the checkbox, you can call UpdateData(TRUE) and that will copy the state of the control in your variable
UpdateData(TRUE);
if (m_checkBox)
{
}
else
{
}
To change the state of the control, assign a new value to your variable and call UpdateData(FALSE)
Note UpdateData() processes all controls that have associated "Value" variables at once.

Damn, I missed that bit.

Yep, I don't like it much myself...

Hello folks,
This one has been bugging me for quite a while, I sort of have a solution but it is quite time conuming.
I have a DLL written in VB.NET that I would like to use in console applciation C++.
Project properties in VB.NET are set for COM interop, and I can see in the registry after I run it.
The problem comes up when I try to use if in C++.
Here is import statement:
#import "\VOT\ADLL\ADLL\bin\Debug\AndrDLL.tlb" raw_interfaces_only raw_native_types no_namespace
but I cannot even expose methods correctly, C++ does not see the interface...
One way to fix is rewriting Vb project to C# project.
Can anyone suggest something better and faster?
Thanks in advance.
Sincerely,
Max Pastchenko

Has anyone, in fact, successfully used a VB.NET dll in C++. I wrote a small VB project that creates dll, which just adds two numbers. I get some exception. While the code converted to C# works fine.
this is my code:
ICalculatorPtr mycalculator("CompareDLL.Test");
long one = 10;
long two = 20;
long lBla;
mycalculator->Add(one,two,&lBla);
if I try to use ICalculator, i get error message cannot create abstract class... 
Sincerely,
Max Pastchenko

Is it possible that DLL project is implemented incorrectly?
I still dont see my interface in the dropdown.....
Sincerely,
Max Pastchenko

.hmmmmmmm
There is something I am confused about now, I hope someone can clarify this for me
SO i have added one method to an interface in VB.NET created DLL used it in C++ works fine. Now, I add another method to it, it does not display second method. When I delete original method from VB.NET code, in C++ it still sees it present in the dropdown but gives me compilation error.
Can someone please clarify this?
Sincerely,
Max Pastchenko

problem solved.
Every time VB builds a project, a .tlb is created (privided COM Interop option is chosen) This tlb is linked with a C++ project that uses .DLL. So when I already have a .tlb and decide to rebuild my VB DLL project a tlb is basically recreated. The solution i found for myself is to rebuild my DLL project after closing C++ project and then opening C++ project again. Of course initializing COM is another thing that needs to be done to properly use DLL

I have a small console program that I have written that seems to execute correctly, but I keep getting a Debug Assertion Failed! error when the program is exiting. And it points to this file dbgdel.cpp line 52 and Expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse).
If I just comple a release version I do not get any error messages when the program exits.
I am stuck on how to fix this error. Is it important that I do fix it?
Any help will be great.

Ok now what?

It looks to me like perhaps you're calling delete twice ? When you delete a pointer, do you set it to NULL ?

I don't see any place that I am calling delete twice. I just got a different error. This one said "DAMAGE: after Normal block (#48) at 0x00F74F18" and when I click on the "Ignore" button then I get the first error message again.
The program does make calles to a third parties api that I am using is it possible that something in thier code is calling delete after my code has finished?
-----------------------

It's entirely possible that a third party API is creating the ASSERT. Look at the call stack to see where the call comes from that ends up with that ASSERT.

Can you set a breakpoint on this line? When the breakpoint is hit, check the call stack to see how your program got there.

You may not get an error message, but the symptom that caused the error still exists.

That all depends on if you want a bug in your program.

Anyone has a hint as to why a service might start successfully on WinXP and Win2003 machines, but not on Win2000 machines?
|
|
|
|
|
How do you define "successfully"? First thought is that you are using an API function that is only supported in XP or W2K3.
|
|
|
|
|
Successfully as in starts up, runs, and keeps running until i decide to stop it. On Win2000 it displays that infamous message box saying that the service cannot start in a timely fashion.
|
|
|
|
|
My first rule of writing services - start a ssecnd thread as quickly as possible, and do all your REAL work in the second thread. Leave the primary thread to report status back to the service control handler and to respond to the service requests.
You probably are doing everything in a signle thread, and on Windows 2000 something is taking longer than the 6 or 10 seconds Win2K is willing to wait before declaring your service 'stuck'.
