I started the jit on dev machine and found a clue that this exection is win32exception and raising in the Windows Application (Form Appliction) which is being started by this service. Here is the what I saw, but I am still not sure why this error comes after 24 processes are started without such error. Any comment?
Errors:
1.
An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in system.windows.forms.dll
Additional information: The parameter is incorrect
And
2.
An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in system.windows.forms.dll
Additional information: Error creating window handle.

Ok, I have a question:
Say I have a panel, and in that panel I have a couple of images, arranged in a row, side by side.
Using a timer, I want to 'grow' one of the images and also allow it to grow outside of the panel control without getting clipped.
Is this possible? If so, how would I go about doing this?

Yes, use scrolled window.

Could you be more specific?
|
|

I don't think you actually draw outside the control. What you could do is:
1) Use a scrolled window as your container control. When the image grows larger than the window, use the scroll bar to view the hidden portion.
Or
2) Support panning capability. Basically, when the image is larger than the window, press the left key and drag the image so that the control window shows the portion that you want to see.
In implementation, you draw the entire image to a graphic buffer and only render a portion of it (the same size as the constrol) to the control window.
Hope this helps.

A control normally won't draw outside it's specified area. Of course you can draw outside the control, but there is no way that you can keep what you have drawn up to date. The control will not get any notification that what you have drawn has been erased and needs redrawing.
Create a new control that has the size to contain what you want to draw, place it on top of your control, and use the new control to do the drawing.

That is right. The source code consists of two portions: your code and compiler generated code. The compiler generated code differs between an App and class library. What you should do is creating a new class library project and then moving your own code to the class library. Also, you may need to change your code to fit class library.
Best,
Jun

I am looking for a commercial component that does HTML editing for WinForms/C#/.NET 2.0, with full source code.
I am using HTMLEditors MSHTML currently (http://www.itwriting.com/htmleditor/index.php), but it is missing too many features, which turn out to be too expensive to develop.
Can anybody recommend on experience with a good HTML Editor component?
Thanks

My name is Brady, and I have never used .NET security. I now have to deploy a ClickOnce application to various external clients. The application unzips files, reads the registry, and does database and file updates. Running in the Internet Zone I see a problem here. Where do I start?
|
|
|
|

Hi Brady
One way of doing it is to add the URL (or website) of the clickonce application to the "trusted sites" zone in Internet Explorer. This should be read by the security mechanism of the CLR.
If this doesn't work - reply again and we'll try something else

Thanks Jakob, I've come right signing the deployment with our cert. That was a relativel easy part. The hard bit was passing command line arguments to the application.

|
|
|

...yup that's another way of doing it 
And - you're right - the command line parameters are tricky

Hi Guys,
I'm getting the following error and it's a very strange one:
______________________________________________________________________________
File or assembly name mlj0rqcf.dll, or one of its dependencies, was not found.
=== Pre-bind state information ===
LOG: Where-ref bind. Location = C:\DOCUME~1\JAVANS~1\LOCALS~1\Temp\mlj0rqcf.dll
LOG: Appbase = C:\Shoprite\MoneyMarket\Electricity\Oostenberg\Electricity.Oostenberg.Forms\Oostenberg.Forms.Test\bin\Debug\
LOG: Initial PrivatePath = NULL
Calling assembly : (Unknown).

LOG: Attempting download of new URL file:///C:/DOCUME~1/JAVANS~1/LOCALS~1/Temp/mlj0rqcf.dll.
______________________________________________________________________________
What makes it strange is that the file mlj0rqcf.dll keeps changing every single time you run the code. To further enhance the strangeness, the code actually works when you pop it into the GAC.
There's no problem that I can see with code and no reason for it to break, but of course I don't know the solution to the problem.

Hi,
I have developed a windows service which starts multiple processes on a client machine and communicates with those. I use multiple sockets and asynchronous communication. This service may require to start multiple processes and to handle communication with those. But I have seen that when the number of client processes reaches 24 the service starts reporting following error. I am assuming this is related to threadpool because total concurrent threads reach at max (25) after 24 processes including one main thread (24+1).
Event Type: Error
Event Source: .NET Runtime
Event Category: None
Event ID: 0
Date: 9/8/2006
Time: 11:05:38 AM
User: N/A
Description:
The description for Event ID ( 0 ) in Source ( .NET Runtime ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event: .NET Runtime version 1.1.4322.573- .NET Framework Initialization Error: C:\WINNT\Microsoft.NET\Framework\v1.1.4322\mscorwks.dll could not be loaded.
I have tried setting maximum num of worker threads and IO Completion threads using SetMaxThreads method exposed by ICorThreadPool interface, but no help.
Any helping comment much appreciated.
Thanks in advance,

I have a mobile app using sqlce 2.0 connecting to an sql server 2000 db. I am able to push, pull and execute sql statements no problem. I would like to be able to "sniff" messaging and data going between sqlce on the mobile device and sql 2000 server with another app(c# .net) running on the same physical drive as sql server, IIS and sscesa20.dll. Does anyone have any suggestions on how to handle this? Thanks in advance for your help!

 hii i am kannan.currently im working with a project in VB.Net. the project is, i've to create a reader for pdf files.the reader uploading a pdf file and user can read it like a real magazine. and we know we are flipping/turns each page of a real magazine to go for the next/Previous page. I WANT THE SAME PAGE FLIP EFFECT IN MY PROJECT.i heard that directx + vb.net wil gimme a solution.
you can see an example reader at www.zinio.com, its free for download. i need the same effect in my project. I have a components that converts each page of a pdf file to image file, which then i need to animate. Can you suggest me some idea. Is it possible using directx.
|
|
|
|
|
I assume it can be done with DirectX (I am NOT going to download random software to see exactly what effect it is, but assume you actually see the page flipping over).
And before you ask how it is done: read the tutorials included with the SDK. If you want to do DirectX there is no shortcut. You need to understand the mapping of coordinates in 3D, how to render your image as a texture over a triangle mesh etc.
Personally I would use WPF - DirectX is a mess to program as you have to deal with the most pathetic and completely irrelevat things like lost device etc).

I have set up an "ActiveX" component by creating a Class Library project in VS2005 and displaying it on a webpage as explained here.
In this Component i am doing some database monitoring and drawing on the form using a timer (System.Timers.Timer). The objects through which i connect and query the DB need to be disposed of when the Component is destroyed/Disposed of, but i can not seem to make that happen.
What i mean is that the Dispose method for my object is not being called nor is my Destructor, when the browser exits.
Is there some other event i could monitor or a way to implement this that i am missing or don't know about?
If any Code needs pasting, please let me know.
|
|
|
|
|
That depends on how you've written your database code. You should be opening a connection, retrieving your data, then closing and disposing of the connection on each Timer tick.

Thanks for the reply dave, and I agree that would be good form, but I thought i mentioned in my first message that I can not do that since i have to poll data from the DB every 1 second, creating the connection usually takes anywhere between 1-5 seconds (depends on the traffic really) so it would be impossible to implement an open->poll->close method which would be able to work every 1 second.
I guess my real problem is that i'm having a hard time accepting that neither my D'tor nor Dispose are called and that there seems to be no notification of the parent browser closing.
or am I wrong about that?
