If you're using C++/CLI ( and if you're not, you're in the wrong forum ), you can still use STL, and the STL list class ships with full source.

I was wondering how to totally take out the title bar windows uses and replace it with a new one in a program like winamp and sonic recordnow does.

Using .NET ?

Odds are then high that you're not using C++/CLI. Try the Visual C++ forum.

Why not? Apple claims a Mac does everything better than a PC, and a Mac has everything you will ever need preinstalled. By the way, you are in the wrong forum since this is the "C++/CLI" forum.

You are in the wrong forum, but the answer is yes, of course. In fact, the Mac I used 6 years ago came with a highly standards compliant C++ compiler.

Is there any builtin button classes in c++? If yes than please do help me.
|
|

|

Depends. You're asking in the C++/CLI forum, in which case the answer is yes. If you mean C++, then the answer is that there is NO GUI support in C++, you need to use frameworks ( like Winforms or MFC ) to write code specific to a platform, in order to render a UI.
Sounds like you need to better phrase your question, and perhaps ask it in the Visual c++ forum.

private: System::Void StartPackingbutton_Click(System::Object^ sender, System::EventArgs^ e) {
int W;//Container Width
try {
W=Convert::ToInt32(ContainerWidthtextBox->Text, CultureInfo::CurrentCulture);
}
int main()
{ int W;
// Enabling Windows XP visual effects before any controls are created
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
// Create the main window and run it
Application::Run(gcnew Form1());
return 0;

Code:
#include <iostream>
#include <vector>
using namespace std;
int main()
{
vector<int>numbers;
int createindex = 100;
while(createindex)
{
numbers.push_back(createindex);
createindex--;

what am i doing wrong?
thanks i'n advanced

Yes, such classes exist.
I recommend asking for more information in the right forum ( this is the C++/CLI forum, you want the Visual C++ forum )

Can anyone help me with saving a text introduced in a text button in a different file?
|
|
|
|

You need to be more clear. Are you in the right forum ( are you using C++/CLI ) ? What do you mean by 'a different file' ? Assuming you're talking about a GUI control, you can ask it what it's Text value is, for C++/CLI the property is .Text.

You want this code in C++/CLI, or in C++ ?

If I want to appeal a windows form, from another form when I push a button, what I should do? I tried this code and I have the following error: Error error C2061: syntax error : identifier 'Results'
private: System::Void ResultsButton_Click(System::Object^ sender, System::EventArgs^ e)
{
Application::Run(gcnew Results());
}
|
|
|
|
|
private: System::Void ResultsButton_Click(System::Object^ sender, System::EventArgs^ e) <br />
{<br />
Results^ resultForm = gcnew Results();<br />
resultForm->ShowDialog();<br />
} <br />
Also, you should include the form header at the top of the form:
#include "Results.h"

Hi,
I have a key, for that i need to change the permissions for admins to full control, system to full control and power usres to only have read access and all others should not have access.
i have written this code,RegSetRegisterKey API is executing correctly, but if i open the registry using regedit, and open the dialog box for permissions, it is not checking the check boxes for full control and read access.
How to make these check boxes to check for the respective permissions.

the following are the questions...can any body here can help me to get this solution...( it can be either in java or c++ )
1. Define a class Income having the interface Pay salary, Compute Deductions, Calculate Tax. Salary consists of Basic, DA, 15% of basic as HRA. Deductions are for the staff canteen and PF at 8% of Basic. Tax is 20% for annula incomes lass than one laks rupees and 30% above this. A tax surcharge of 10% is additionally charged for the latter income group.
2.Employees have a number, date of birth (dd mm yy), rank, and salary. When an employee is first recruited then all these are given values of 0. Upon confirmation, the actual values of these are entered for the employee. Employees can be given a salary raise of 10% of their previous salary. Their rank can be incremented by 1 and when this happens an employee gets an increment of 25%.
i would very much thankful if you guys can help me....
