Hi All,
I'm trying to overload the assignment (=) operator so that I can achieve the following:
int x = myclass;
instead of:
int x = myclass.Value();
I am implementing it as follows:
class CMyClass
{
private:
int m_nValue;
public:
int& operator=(CMyClass& class);
int Value() { return m_nValue; };
};
int& CMyClass::operator=(CMyClass& class)
{
return class.Value();
}
But I keep on getting a compiler errors either saying that there is no suitable conversion, or that it cannot convert from CMyClass to int.
Clearly my syntax (or something) is screwed, so how can I fix it ?
Thanks
OD

This forum is meant for managed C++. You have rightly asked it in VC++[^] forum. So, please dont cross-post.

How can i get the system time?

|
|

DateTime.Now. If this does not work, then you're not using C++/CLI, and have asked in the wrong forum.

Use GetSystemTime.
SYSTEMTIME systime;
GetSystemTime(&systime);
ps. Question not involving CLI should be asked in VC++[^] forum.

Hi,
I'm trying to deploy an application written in C++, C++/CLI and C# on pc's that do not have VC2005 installed. I am having issues with assemblies loading, in particular the C++/CLI one and am getting FileLoadException when it tries to load the dll. I know I can get round this problem by running Vcredist_x86.exe - this sorts it out and sets the pc up so that it can run VS2005 apps.
My problem however is that not everybody is able to run this exe as you need admin rights as it's an installer, so I just want to be able to ship the appropriate dlls with the application. These can be found in the folders in \Program Files\Microsoft Visual Studio 8\VC\Redist\x86\ in my installation. However, even with these dlls present in the application directory (both within their directory structures and just all copied straight into the root directory), I'm still getting the FileLoadException when trying to load the C++/CLI dll. Does anyone know what else Vcredist_x86.exe does, i.e. what other dlls it puts on the users pc. I feel like I've tried all avenues but am not getting anywhere...
There's a lot of detail about this at http://www.codeproject.com/cpp/vcredists_x86.asp but I've tried it all and the only way I can get it to work is by running the VcRedist_x86.exe which unfortunately isn't an option.
Thanks, Stuart

Hi to all, I'm new to vc++ and I've read a bit on how to create a new form and load it (make it appear on screen). But i have this code and its corresponding error and would be glad if someone could point me in the right direction.
There's three forms, Form1 (login form) and gymMain a main interface. So what I tried to do is first load the application with gymMain and make its Visible state FALSE, next load Form1 (login) and upon confirmation of input, close Form1 and make gymMain visible. Now I try this with the below code and the erorr is shown below. All help/suggestions appreaciated.

As said earlier Form1 doesn't seem to member of GymManager, which is assumed by you while coding.

If I have a populated dataGrid in visual c++, how can I get values from the dataGrid without going to the underlying dataSet.
Is there a way to use dataGrid->currentRowIndex to reference the row and then return the value from a given column.
Thanks!!

You need to populate the dataset...

How do I perform a global hit test?
I want to translate the mouse coords to a global hit test result which will hopefully give me the window handle that the mouse is over and if possible, if I am over the title bar/menu/status bar etc.

Hi everyone,
I set my main form's icon. When I tested it in debug mode, a System.Resources.MissingManifestResourceException gets thrown by at the point where the forms designer code attempts to load the icon:
this->Icon = (cli::safe_cast<System::Drawing::Icon^ >(resources->GetObject(L"$this.Icon")));
When I view the .resx file in VS however, I can see the icon is there. Does anyone know what the cause of this problem could be?
TIA,
Ralph

I discovered that my form was declared inside a namespace `Configuration1'. The name of the project is `Configuration'. Changing the namespace to `Configuration' seems to have solved the problem.

II would like to capture the word (text) under the mouse from any program in real time. If the mouse pauses over a word, I would get a callback or notification that includes the actual text. This would not be limited to my own program. I want to catch the text on any program.
I know I could watch the clipboard and use cut or copy to get the text from another app.
I want to make a program that checks the word against a local word table so that my program window can show information about the word the mouse is over.

Are you using C++/CLI, or are you in the wrong forum ?
there's an API called GetWindowAtPoint ( from memory ), which would allow you to call GetWindowText. Getting the word under the mouse is a little harder.

Looking for someone who has basic knowledge of writing a AMX plugin for CS 1.6
Basically it has to take a command the admin does and store it in a text file on a server to check for proof of admin abuse.

What's CS 1.6 ? It supports .NET ?

Counter-Strike 1.6.
The admin commands are input through Steam at www.steampowered.com
I tried to google to see if Steam supports .NET but nothing came up
-on the other hand-
There is a "guide" at www.amxmodx.org on the constants and such. They also have downloadable plugins and you can open the .sma files in notepad. The following is a link to plugins that record stats:
http://www.amxmodx.org/compiler.php?mod=2&cat=3&plugin=&author=&go=search[^]
So pretty much when admin uses: amx_kick or amx_slap or amx_ban it needs to record his STEAM id and write it to a text file in the database.

Hi all,
I'm having trouble with my multithreading. I am doing video capturing so have and infinite loop in which frames are captured, unfortunately while the thread is running the class (containing the loop) the UI freezes.
I'm wondering if anyone knows how i am able to create a simple worker thread which executes the class and keeps the UI responding?
Here is the code that executes the class. I have attempted to create what i thought was a worker thread, with no avail.
<br />
private: System::Void button2_Click(System::Object^ sender, System::EventArgs^ e) {<br />
<br />
ThreadStart^ t1 = gcnew ThreadStart(this, &FYProjV4::Form1::detectThreadStart);<br />
Thread^ recogThread = gcnew Thread(t1);<br />
<br />
recogThread->IsBackground = true;<br />
recogThread->Start();<br />
<br />
<br />
}<br />
<br />
private: System::Void detectThreadStart() {<br />
<br />
if(reportBox1->InvokeRequired == false)<br />
{<br />
<br />
FaceRecognition recogTools;<br />
recogTools.StartRecognition(reportBox1, faceBox1);<br />
}<br />
else<br />
{<br />
<br />
this->BeginInvoke(gcnew DetectThreadStartDelegate(this, &FYProjV4::Form1::detectThreadStart));<br />
this->EndInvoke(result);<br />
<br />
}<br />
<br />
}
I am in a real rush to get this sorted so any suggestions would be greatly appreciated.
Also, Removing the loop is not an option and it must be in managed c++.
Thanks for your time
