Many applications now use the .NET Framework - The user may already have it.

You can always point them to the download page on the MS Website to obtain their free copy of the .NET Framework

* Download .NET Framework 1.1[^]
* Download .NET Framework 2.0[^]

Again, I'm not trying to be harsh here, but you chose C# as a language to develop your software in. If the size of the framework is too big then you should have thought about that in advance rather than whine about it now.

Yes.

See this for 1.1[^] or this for .NET 2.0[^] and look for "Creating a Single Setup Project to Install a .NET Framework Application"

That is the concept of .NET. If you don't want to install the .NET Framework, then don't write codes in C#. Just use the old C++.

Something Added.
If you run a application based on .Net Framework 2.0 ,but there is only 1.0 or 1.1,the application will not run ,too.The .Net Framework 2.0 is required. Smile | :)

From Wikipedia - a design pattern is a general repeatable solution to a commonly-occurring problem in software design.[^]

In Windows Forms, the most popular design patterns are Model View Controller (MVC)[^], which is what I used most especially with MyXaml.

Also starting to take hold is the Model View Presenter[^] pattern.

Hi guys! Help please I am a newbie in C#, I have been working on an application and was working fine on MS Visual C# .Net and then yesterday I downloaded and started converted the application to MS Visual C# 2005. Now on one of the forms I am getting an error when I try to open the form. i.e. form.showDialog(); the error says Invalid OperationException was unhandled and that DragDrop registration did not succeed.

Try reading this MSDN forum thread, it may help: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=226434&SiteID=1[^]

Basic solution from one of the answers is this:

"To solve my problem, I went into the Project Properties->Configuration Properties->Linker->Advanced and set CLR Thread Attribute to -> STA Threading."

Hope this helps!

Hi Mike,
I don't have configuration properties under my project properties. I am using MS Visual C# 2005 express edition. Are you going Project-->project properties--->Configuration properties? I went this way and when I go from Project--> project properties, there is no configuration properties or anything about STA threading, please advice?

sasa,

I did some digging and it appears that the blogs are misleading. The Linker property is only for C++.

That said, you might try reviewing the information here on setting STA threading in your application to see if that fixes it.

http://msdn2.microsoft.com/en-us/library/system.threading.thread.setapartmentstate.aspx[^]

Additionally you should review the information here: http://blogs.msdn.com/adam_nathan/archive/2003/07/18/56727.aspx[^] if your C# application is using managed C++ code.

Unfortunately I've never experienced the issue you're seeing so am unable to provide you with a definitive answer.

Sorry, and hope this helps!

Hi Resource based application is one of the best solution for Multilingual Applications. Don’t bother about back-end, just convert the field types Char to Nchar and Varchar to Nvarchar, then it supports any type of languages.

IE Toolbar not moving

There are several examples of how to create an IE toolbar in C# on CP. All are based on this article posted http://www.codeproject.com/csharp/dotnetbandobjects.asp[^]

The one issue that I am having is that my toolbars refuse to move to a new row. I can move my tool bar to any band (row) but if I keep moving it down, to below the lowest band, it will not add a new one. All other toolbars can be moved to a new row/band. Just not mine.

Well actually, if I look very carefully, it does. Its very very very narrow. I have tried nearly every trick, but I just cannot get this to work.

Any ideas?

Re: IE Toolbar not moving

Ranjan Banerji23-Jun-06 17:43

Fixed it. The sample code had a bug in it. in GetBandInfo ptMinSize.Y was being set to -1. So if another toolbar had not created any height for the band, your toolbar would get squished.

Rectangle onclick event

Hello,
I am drawing a table in the OnPaint method of a windows form. I would like to add Rectangles to the page that will fire an onclick event when I click on them. Does anybody know how to accomplish this? As far as I can see, the rectangle object doesn't have that kind of functionality built in... I originally just tried using buttons, but since I need quite a few of them, it is taking too long to draw them.

Thanks for your help!

VS 2005 has a new control called "TableLayoutPanel". You may want to try this before writing your own rectangles. The panel certainly supports click events. Check this CP article[^].

Determining if string user input is file path, URL, or network path. [modified]

Hi all,

Right now, I'm struggling with finding a solid way to determine what sort of string the user has input. The strings I want to support are URLs, paths to files, or network paths. I've tried playing with the UriBuilder class and just building my own string "URI" (properly formatted so the URI class doesn't throw an exception).

Does anyone have any ideas? Pointers on where to look? I know that URIs can do most of this, but it doesn't seem to like network paths and is pretty prone to exceptions.

Thanks in advance!

What does the byte array contain?

a) The full bitmap with headers and pixel data: Write in into a MemoryStream and create an Image with Image.FromStream().

b) Only the pixel data: Copy the array into unmanaged memory, create new Bitmap with the expected width, height and PixelFormat, lock all bits and set Scan0 to the first element of the unmanaged array. Go on, just copy the code from this FAQ ^.
