The constructor of CString only reads till the empty character, that's why.
You can however do
CopyMemory(sTemp.GetBuffer(count), str, count);
sTemp.ReleaseBuffer(count);

str[0]='';

Hi,
I have a dialog based application. I have added the tree control on it. The tree implementation is done in separate class. I am getting the mouse click event in the class where I implemented tree control. I want the mouse click event to pass to dialog class i.e ..dlg to do some other operation. How to do this?
Thanks:-
Mike

You can insert below code to treectrl's mouse event function.
#include "YourDlg.h"
CYourDlg*dlg=(CYourDlg*)AfxGetMainWnd();
dlg->'Your function in your dialog class'

I define a class in a DLL(DLL1) and make a singleton using Loki library,for example:
class A
{
public:
......
void fun1();
void fun2();
.......
};
typedef Loki::<A> SingleA;
the singleton is used in DLL1.
I use SingleA::Instance() in another DLL(test dll) When I test DLL1,but all test failed.Why? How to resolve it?
|

Presuming you're actually using this code to define the singleton:
typedef Loki::SingletonHolder<A> SingleA;
then each module (DLL or EXE) that references A will have its own copy of hte singleton. This is because of how the 'static' keyword works in C++ classes.
If you want one singleton in the whole application, then provide an accessor that's exported from the DLL and declare the singleton in one of the source files in the DLL.

Hi! I've been using PeekPocket ( http://www.codeproject.com/KB/mobile/PeekPocket.aspx ) to scan Wifi stations and to get signal strenghts of each one.
It has two custom tabs. I've added a 3rd one, in which I send the lat/long (I've previously calculated) to googlemaps and it would show as a webpage.
The point is that the project is dialogbased and I dont know how to add a WebBrowser control in that 3rd tab.
I've read WebBroser control in Compact .NET ( http://msdn.microsoft.com/en-us/library/ms229657.aspx ) and it needs...
This example requires references to the following namespaces:<br />
<br />
* System<br />
* System.Windows.Forms<br />
If I add that namespaces could I get what I want?
What are the lines to add that namespaces?
Or if you have another idea to show a webpage in that application...  )
Thanks in advance!

I am currently developing a GUI based application using MFC and C++. While I am far from done, I am trying to think a head to the testing phase. I have been told that Winrunner is the de facto standard for testing GUI based applications today. However, I have seen prices on the web for Winrunner in excess of 6000 dollars. That is way out of my budget. I am wondering if somebody could recommend a cheaper (or ever free) tool that is similar to Winrunner.
Thanks
Bob

Did you try the UWSC[^] tool. I havent used the Winrunner. so am not sure whether this tool will cover all the functionalities of the WinRunner or not.

nave,
Thanks for the response. I took a quick look at the tool and I am going to take a more in depth look at it. However, I still have a bunch of bugs that I need to fix. At the moment, these bugs are going to take priority over finding new bugs.

Hi All,
I'm a pretty experienced programmer but can't figure how to see the value of some variables when in debugger - either Watch Window or the Immediate Window (.NET 2008, C++).
The Watch Window lists them as :Out of Scope. At the least any variable passed into a function is not visible. Example:
void MyFunction(int x, Int32 y)
{
int i;
i = x * y;
}
i would be available but x & y are not. I've tried some project settings, optimization is off.
Any help?

I tried your example and the debugger could show the values of i, x and y. I am doing this in debug mode. I am not sure why you are having a problem. If you could post the entire program that might help. Not sure.

I presume the PC is pointing within the function? I compiled and linked your code and I was able to see the parameters.

The breakpoint where the program has halted on is probably outside MyFunction.

Hello,
I have an application which can start DLL. This DLL should open own window and output some data. I only know that using MessageBox it is possible, but I would like to have more advanced window. Can DLL do it or only application can open/control windows ?
If you have some example I would appriciate. I already tried and created cpp MFC code
with wizard for SDI application than tried to compile it as DLL but it failed.

Hello all,
1. In VS, I've created a Square.cpp file which contains the following:
double square_in_C(double &arg) {return (arg*arg);}
2. I've created a .def file containing the following:
LIBRARY MyXLib
EXPORTS
square_in_C
3. I've added a Module to an Excel file containing the following:
Declare Function square_in_C _
Lib "C:/PATHTOFILE/debug/MyXLib.dll" (arg As Double) As Double
4. Cell B4 contains the number 4. Cell B6 contains "=square_in_C(B4)" (without quotes).
The result in B6: #VALUE!
Anyone know what I'm doing wrong?
Thanks

Can you debug into square_in_C() to see if the function is being called?

Have you verified via Depends or Dumpbin that the exported function is named as you think it is?

I can't exactly call the method to debug in the DLL because there isn't a main method.
And i've tried using Dumpbin.exe at the cmd line and I get:
This application has failed to start because mspdb80.dll was not found.

What does a lack of main() have to do with it? Using something as antiquated as fprintf() (either to a file or the screen) would suffice.

It sounds like an environment variable/path issue. Copy (temporarily) dumpbin.exe to the folder containing mspdb80.dll. See here for more.
