Hi,
I am invoking the delegates asynchronously(using Begin Invoke).
These delegates are not invoked in the invocation order .
How to make this delegate to raise in the invocation order.
Thanks in Advance

I'm not sure you can control the order in which delegates are invoked.
Instead you could use a System.Timers.Timer object (which will execute on a thread pool thread) and a synchronized list of work items. You add work items to the list and the timer routine takes them off again.

Hi all,
I want my Console.WriteLine(...) output to be saved in a text file AS WELL AS displayed on the console screen.
I know how to get the output to go to the text file instead of the screen (use Console.SetOut to the stream provided by a new StreamWriter, say). But I can't get the output to go to BOTH!
I am probably being very stupid, and there is a simple answer, but all the google hits discuss the situation where you want the output to go to the text file instead of the console window.
Thanks for anything you can suggest!

Whether you want to generate a dynamic function, write a dynamic algorithm or want to handle delegate inline, anonymous functions have always been at your service. However one area where in anonymous function lacking is, making a recursive call. Since it does not have function signature it’s not possible to make recursive call, at lease not directly. This article shows you how to achieve that.

Why post this here? Why not make it into an Article? It seems like it would make an excellent article.

Hi everyone!
My problem is that i have a user control. It has an ArrayList, in the ArrayList there is a collection of Buttons. I can set up these Buttons at designtime, but when I go to run the program, it seems to clear out my arraylist.
Why would it do this? Am I missing some vital bit of code that is needed in the transition from designtime to runtime. The code I use is below. Any help would be appreciated.
the hbHoverButton is another control of mine, but I assume that its the same problem even if I change the control.
Thanks

I am working on creating a windows service. Here I have to watch a folder for any file that is placed in that folder. If a file is placed in that folder i have to process it. I am doing this with the filesystemwatcher component's created method. This works fine when i am placing files one by one. But when i place 5 or 6 files at the same time, or when i place a file of bigger size, say above 3 MB, it produces error, saying that the an system.ioexception has occurred. The file is being used by another application. I think this is due to the fact that the windows takes some time to copy that file to that folder, whereas filesystemwatcher components starts it's execution as soon as it finds a file in that folder.
Any suggestion will be very welcome

Hi
Create a seperate thread in which you will process that file. For instance, if you have 5 files moved into the folder, you will be having 5 threads that would process those files. In every thread, make a variable that would be having state of the file. whenever a file is copied into the filesystem, filesystemwatcher trigers Created event once and then Changed event twice. When the Chnaged event is fired for the same file for the second time then start doing anythng on that file.
Hope it helps

Khalid

Hello,
I need to check the version of DLL library that I'm using in my program. How do I do that at runtime?
Thanks much for any input.

hi Michal,
i don't know exactly but i hope this information is going to help u. just paste this link on ur browser and c: www.codeproject.com/system/library_version.asp

Thanks, Rahithi,
but the article at your link deals with C++ code. Do you know about any C# example?
Thanks,
Michal

Michal,
sorry for sending the wrong article.
as per my knowledge(i am new to .Net) If it's a managed assembly you're loading, you can check
System.Reflection.Assembly.GetName().Version.
and For native DLLs you can use the FileVersionInfo class.
hope this will help
regards,
Rahithi
|
|
|
|
|
Rahithi,
thanks. It's a COM library I'm referencing, so I can't use the System.Reflection namespace directly I guess. But maybe I could use the System.Reflection namespace to get the external DLL's version by using a non-static method System.Reflection.Assembly.GetModule().ModuleVersionId. But I have yet to find out how to do that.
Unfortunately, getting the fileversion information thru FileVersionInfo.GetVersionInfo() doesn't work neither since it keeps returning "1.0.0.0" for a DLL that has a Runtime version of "v2.0.50727".
What am I trying to accomplish here is to get the information that's visible in the Properties tab under "Runtime Version" if you click on the appropriate library in the References solution folder.
Any idea?
Thanks,
Michal Kreslik

I'm using a monospace font and trying to use e.Graphics.MeasureString("0", viewerFont); except the width that returns isn't the right width. I've tried using the two MeasureDisplayStringWidth functions in an article on here, but these also produce the wrong values. The bitmap drawing one is the closest so far. I just need to know how many pixels a single character is, I don't see why that should be so hard to do

Actually we want to crop certain area from the image,so for this porpose we try this code...but now the problem is that although we got the reactangle

RectangleF Destinationrectangle=new RectangleF(530,30,100,190);
RectangleF Sourcerectangle=new RectangleF(topleft,topright,bottomleft,bottomright);
g.DrawImage(this.BinaryImage.Image,Destinationrectangle,Sourcerectangle,GraphicsUnit.Pixel);
Now We Want to convert Destinationrectangle into Bitmap,(Is this Possible),and plz guide us how to insert this bitmap in to pictureBox
