You can have your program ask whose turn, as:
C:\game.exe
Game starts!
Player-A: format = (value, x, y) <-- playser A's turn to input
3, 1, 1
Status:
3 0 0
0 0 0
0 0 0
Player-B: format = (value, x, y) <-- player B's turn to input
5, 3, 1
Status:
3 0 5
0 0 0
0 0 0

Hello,
i want to embed a dialog in an SDI Window. I created a new SDI project
without Doc/View architecure. Then created a new dialog, disabled the border,
system menue etc.. Now, in the designer the dialog looks like en empty gray plane.
I also added a class to this dialog derived from CDialog. I did this with the designers help,
right click on the dialog and "add class".
My goal is to embed this dialog in the ChildView window and make it as large as the ChildView
window. I found an example here on code project thats similiar to my problem but anyway it
doesn't meet my requirements.
So, how can I embed this dialog in the SDI application?
best regards,
cmos

Hi,
1) Is it possible to add additional textbox control (or a button) to all open/save file dialogs in winXP and vista?
2) Is it possible to replace them with my application?

Hello,
We would like to print some simple drawing output using GDI. We have used the PrintDlgEx function to obtain a device context handle to a printer, but are unsure of how to proceed. We have not been able to find much example code and are a little stuck.
Basically, we have the DC handle. Presumably we then call Rectangle(x,x,x,x) etc to do the painting. What must be done then to initiate the actual printing?
Any help would be appreciated.
Thanks,
Steve

That is not quite what we were looking for because we are using pure Win32, no MFC. However it did lead me to find this so for that you have my thanks. I spent ages looking on the MSDN site for something like that.

You will need to put all GDI calls between StartDoc/EndDoc and StartPage/EndPage APIs.
The Doc indicates a print job and the Page indicates a new page.
So basically you will have one pair of StartDoc/EndDoc and several pairs of StartPage/EndPage (One for each page).

I'm trying to compile the SysInternals Native app[^] for XP x64 (and other Windows x64 ), so I can create an app which can run during boot-time (similar to chkdsk), but am not having much luck. As SysInternals have stopped supplying native.xip, you can get it from
http://www.dowers.net:8080/ftp/Programs/InsideWin2000/Sysinternals-Website/NATIVE.ZIP[^]
I've installed the Windows Server 2003 DDK, and have started a Windows Server 2003 Free x64 Build environment (using the shortcut). I've then copied all the Native sources and makefile to ddk\inc, as instructed to do so at the bottom of the linked article. However, when I run build.exe, I get two identical errors:
C:\WINDDK\3790~1.183\inc>build

How can I fix it ?
Is there any good information on how to correctly setup a build environment for building native apps for both x86 and x64 ?

You might have much better luck posting your question on a site that's devoted to driver development. They know all about this kind of stuff.
Try this site:
http://www.osronline.com/[^]
Good luck!

I think you should install the latest version of the DDK (WDK).
The one you are using is very old and probably does not support x64.
The new version, the last time I looked was something like 6001.18002.

Hi.
I'm new in c/c++... and I'm a little confused...
I made a dll in c/c++ (using some example I saw on-line), and now I want to load it in a new project, but it doesn't work.
I paste the dll file in the project debug folder, and I'm using
HINSTANCE myDll = LoadLibrary((LPCWSTR)"TestingDll.dll");
to access to it, but myDll is always empty...Can anyone tell me what possible I'm doing wrong?
Thanks
|
|
|
|
|
All the various dlls that TestingDll.dll is dependent on wuould not be present.
Check out the dependencies of TestingDll.dll using depends.exe and paste all those dlls also in the same folder.
|
|
|
|
|
Thanks for your atention...
At the beginning I thought that was the problem and decided to do something very basic for testings, but I still can not access to it.
For my testings I made:
//MyDll.cpp
#include "MyDll.h"
namespace Functions{
Person MyFunctions::first() {
struct Person myPerson;
myPerson.name = "asd";
myPerson.age = 123;
return myPerson;
}
}
//MyDll.h
namespace Functions{
struct Person {
char *name;
int age;
};
class MyFunctions {
public:
static __declspec(dllexport) Person first();
};
}
Then the DLL file I paste in the new project folder (only this one, because for my point of view I don't need nothing more, because it is very simple and doesn't use/depend nothing more ), right?
In the new project I made:
#include "stdafx.h"
#include "windows.h"
using namespace System;
int main(array<System::String ^> ^args){
HINSTANCE myDll = LoadLibrary((LPCWSTR)"TestingDll.dll");
if(myDll) {
Console::WriteLine("DLL loaded \n");
}
else {
Console::WriteLine("DLL failed to load \n");
}
return 0;
}
And the result always is -> "DLL failed to load".
It doesn't returns any error, but doesn't do what I want .
I apologize, but due to my inexperience I did not understand the problem that could cause this ( for sure is something that I'm doing wrong, or forget).
Can you help me?

From LoadLibrary documentation [^].
Return Value
If the function succeeds, the return value is a handle to the module.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
BTW possibly you should put the DLL inside the project folder.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

Thanks for your atention...
I already have the DLL inside the new project folder, but it still not work  and I couldn't understand what could be the cause of this, because it doesn't return any error...

As stated by the documentation I linked in my previous post, if the LoadLibrary return HANDLE is NULL then you have to call GetLastError in order to get some understanding of what's happening.

Perhaps your quote on Creation could be applied to the other Lord who has created so many dialects of C with so many obscure confusions in syntax.
