It already is, open your project directory and take a look in the bin\Debug or bin\Release folders. Note if you want the release version then select the solution node in the Solution Explorer Pane and change Active Config to Release.

Just Google it.

Sorting columns in listviews

Hello!

I have been trying to use some of the examples on sorting columns in listviews that are published on for example http://www.codeproject.com/cs/miscctrl/ListViewColumnSorter.asp[^]and some other places but I keep getting this error:

Error 1 Using the generic type 'System.Collections.Generic.IComparer<t>' requires '1' type arguments

I guess it something that has changed with later versions of C# and I wonder if anyone knows how to solve this?

Best regards,
Hampus

You need provide a generic type argument for your IComparer, e.g.

IComparer<int> comparer = new MyIntComparer();

The <int> bit is the bit you seem to be missing, note this is just an example.

Just Google it.

Help with GUI and making a menu item execute another file

Alright, I have my GUI written in C and the other document is in command-line and written in C++. I'd like to merge one code with another on a click of a certain menu item and I do not know how to do so.

My main.cpp looks like this:

#include <windows.h><br />

#define IDI_MYICON 201//Defines the Icon ID<br />

#define ID_CONVERT_MM 9002//Defines menu item "MessengerMate"<br />
#define ID_CONVERT_MIDDLE 9003//Defines menu item "Middle_Man(Coming Soon..)"<br />
<br />
<br />
const char g_szClassName[] = "myWindowClass";//Defines window class to be used.<br />

All this info is just to give you an idea of what I want to do since I'm not too sure what the technical term for the procedure is. Also, whenever I move the installer out of the directory that the icons are in, it'll produce the errors and i'm wondering how to fix it to where no matter where the installer is, it shows the icons. Sorry i'm a newb.

Any help is greatly appreciated and if I have any other code wrong please inform me.

A System.Windows.Forms.Form object got a Text property, which is the title of the window.

If you're in the class derived from Form (for example in the Load event handler), you can set the title text by

this.Text = "New titlebar text";

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

DataGrid sort problem

25-Sep-06 3:21

Hello, here is my problem. I have a DataGrid control with some columns. My question is about two of them. When I enter a value in any cell of the first column I want to calaculate (by expression) the value of the second column by using the value of the first column in the same row. OK, I have a function which does that and works fine, but when I click to sort the DataGrid it doesn't work correct. I use DataView to navigate through the records in a DataTable. All of the columns are in this DataTable. Where do I make a mistake? Can somebody help?

Preserving an entire object when redirecting to another web page??

Goalie3525-Sep-06 2:58

25-Sep-06 2:58

I'm creating a website and the portion I'm working on now involves two web pages. The first page creates an image object and then I'm basically doing a response.redirect to the 2nd page however this 2nd page needs to access the original image object that I created on the 1st page.

So how can I preserve an object so that it's accessible across multiple pages?

Normally I wouldn't require a 2nd aspx page to utilize the same object however in this particular case, with what I'm trying to accomplish, I need to perform it this way.

Thanks in advance.

That won't work. Either you find out how the program displays its graph -usually using a dll or something, which you can use in your application by referencing to it. Watch out for copyrights here-, or you use a graph library yourself. You can find plenty here in CodeProject.
