Hi!
Someome can help me to solve this problem?
Package 'Visual Studio Explorers and Designers Package'has failed to load properly (GUI={8D8529D3-625D-4496-8354-3DAD630ECC1B})because of previous errors. For assistance, contact the package vendor. To attempt to load this package again, type 'devenv /resetskippkgs' at the command .
I use this command but no result.
Thanks

I'm using the winsock API in my VC++ 2008 app.
When the application is running and the socket is connected all the time reading/writing, I unplug the network cable to force a network problem.
In order to check if the connection is down I just send 0 bytes to the socket, but I still returns 0 instead of SOCKET_ERROR.
Does anyone know how to check if the connection is down?

I front with a serious problem on VC6 environment on Win7 ... when I try to open a file ( not a project ) the environemnt crush down -- it's describe here http://support.microsoft.com/kb/241396[^]
and the solution too ... I download this project, I compile, succesfully register FileTool.dll, but when I try to AddsIn this dll into VC6 environment ( Tools -> Customize -> Add-ins and Macro Files ), I get this error :
Unable to register this add-in because its DllRegisterServer returns an error ...
I think that I succesfully register this dll because when I registered I get this message :
DllRegisterServer in FileTool.dll succeded.
Have you put face with this kind of problem ? Any hint will help a lot. Thanks.

I haven't tried the solution you describe here, so I can't comment on that, but running VC6 in compatability mode with Windows XP solves the problem for me as well.

hello all, I have coded a round robin scheduling program using visual c++ , version 6.0. I want to add some simple graphics in my code so that a graphical representation of RR scheduling can be made. But, I don't know how to add graphics in visual c++. Can anyone of you give a suggestion or advice? Can you give me a sample code so that I can understand how to change my code to add graphics in it? Thanks.
Here is my code:
#include<stdio.h>
#include<conio.h>

scanf("%d",&n);

Assuming that you know how to create a Windows based application then you should start here[^] to learn GDI+.

I have a window derrived from CWnd which contains a number of rectangular areas. I would like the cursor to change shape when the mouse pointer is within any of the rectangular areas and I wondered if anyone could offer some advice as to what steps I need to take to do this.
Thanks
Tony

Override the CWnd::OnSetCursor() function. Call the Windows SetCursor() function to change the pointer.

The following error is referring to a variable that has a stale value.
Data4 CXX0017: Error: symbol "IID_IShellItem" not found
What does this mean (What is a stale value)?
Thanks!
|
|
|
|
|
Basically, the value could be retreived earlier however, there was a problem retreiving it on a more recent attempt.
See here[^]
|
|
|
|
|
Here is a stupid question...this means at some point the pointer went from a good pointer to a bad one. Is the stale value the address of the original memory location where the data was or a completely new location? This is meant to be a general question about what the stale value actually is....I think I understand that it was once valid.

Hi Experts,
I have 2 files ( .h and .c) I added in MFC dialog based application but I am getting linker error.
Is there any special thing to add .c file.

Are you certain the file is compiled as C++ ?
What link errors ?
Are you referencing an external library ?

yes, I am getting linker error 2019, 2001.
error LNK2019: unresolved external symbol "void __cdecl Unload(void)" (?Unload@@YAXXZ) referenced in function "public: void __thiscall CTestDlg::OnBnClickedButton2(void)" (?OnBnClickedButton2@CTestprotDlg@@QAEXXZ) TestprotDlg.obj
|
|
|
|
|
So, in function CTestDlg::OnBnClickedButton2() you have a call to function Unload() , but the linker cannot find it. Where is function Unload() declared?
[edit]I suspect that your source file should have the exctension .cpp rather than .c if this is an MFC project.[/edit]
|
|
|
|
|
Where is the "Unload" function? Is it in the file you added ? are you certain the file is compiled ?
Watched code never compiles.
|
|
|
|

I'm assuming certain things since you're haven't shared any code with us.
I assume that the Unload function is written in the .c file and its declaration is available in the corresponding .h file.
Now I believe that you're calling the Unload function from a routine in a .cpp file.
Since C++ compilers do name mangling, the Unload function name will be internally changed.
To prevent this from happening you must include the header file within an extern "C" block.
extern "C"
{
#include "my_c_header.h"
}

NB: As indicated in a reply the issue has been solved. The DirectX module was changing the floating point precision.
A colleague is calling the constructor of a class which takes two doubles as arguments. Each argument he passes is the sum of two doubles:
CGridPoint( a + b, c + d)
The class object stores the two values internally. When he views the result he sees that the values have been rounded to 1 decimal place.
The values are not so large that this would be expected. Here are example:
a = 44.445472717
b = 724631.800000000
a + b = 724676.250000000
In other words he passes in 44.445472717 + 724631.800000000 as the first argument to the constructor and the result is stored internally and is seen to be 724676.250000000.
Does anyone know the cause of this rounding?
BTW he uses VS2008. This works in VS2010.
