Have you looked up C# COM late binding? I just did a google search and found a good hit[^].
|
|
|
|
|
Well, I have. I feel like I've googled my brains out for this.  All I've found is that it seems to be possible, but not HOW!
Thanks for the link it contains almost what I need, unfortunately it only shows how to pass an ordinary variable (a boolean). My dll requires a user-def type, question is how to "build" a similar type in c# (or how to convert a c# struct to a vb type maybe)?
|
|
|
|
|
I found an "intermediate" solution - to make another dll containing the user-def types (as these aren't changed that often) and add this as a reference in both the C# application and the Vb6 dll.
That way I can call the main dll with late binding, both c# and vb recognize the Type / Struct and I don't have to rebuild the app when I change the dll's functions. Until I decide to change the Types of cause... 
It's not the ultimate solution, but I think it'll work.
Thank you for the help!

I would like to securely hide a connection string from anyone trying to break my C# assembly. I know I cannot just stick my connection string within my C# assembly because the use of Reflection would reveal it. Even through an Obfuscator the connection string can be somewhat hidden but not very securely. Putting the connection string in the app.config file and having Visual Studio automatically encrypt it is still not very secure in my eyes. I was thinking about storing it within a C++ unmanaged dll to prevent the use of reflection but I dont know if that is secure and also how do would I stop someone else from using that C++ unmanaged dll?
Has anyone found a good method out there that can be totally secure without using third party software and without using a web server?

For actual security you would need a password to be entered on application startup allowing you to use the System.Security.Cryptography namespace's cryptography classes.

How to change the batch file icon to designed icon
naveen
|
|
|
|
|
you can only replace the icon for all batch files! a bat file can't contain any kind of resources.. bat files have only very limited features!
|

|
|
ok thanks,
How replace the icon for all batch files
naveen
|
|
|
|
|
open windows explorer - tools - folder options - file types.. select the file extension and press advanced - select icon.
|
|
|
|
|
You could create a shortcut to your batch file, and change the icon of the shortcut,
maybe that is sufficient for what you need.

You ARE asking the same question, you just re-worded it. Infact, you posted your first message, then because no-one had answered, you reposted it with slightly different wording three hours later under a different user name.
And now your asking it again.
If people know the asnwer, they will reply. There is no need to repost your question.

Good ol' pie, it's been a while.

Hey - I'm one of the volunteers who wades through crap like this on a daily basis. More importantly because I do this regularly, when I see the same question appearing in a slightly reworded form, I tend to see if this person has posted this before.

Errmm. No. I gave you this answer to alert you to the rules we all follow for posting. Simply asking the same question in different ways does not qualify you as having asked different questions. It just says you've reworded your question to get it to the top and that's not fair on others.

I would love it if I didn't have to do this. However, when people like you abuse the system like this, then I feel it my duty to inform you of what you have done wrong so that you respect others. Believe me, I would expect others to do the same to me if I had abused the system like this. Oh yes, and who am I to ask this question? I'm the guy who wrote the article[^] on posting questions in the forum.

Don't be so rude, please.
It has been explained to you where you broke the etiquette of the forum so I won't reiterated it. However, I will say that I agree with what has been said already.

Hello!
I have the following situation:
A server should call event, which are being handled by the client.
So i took the example posted on codeproject http://www.codeproject.com/useritems/RemotingEvent.asp (Remoting Event) and merged it with my existing code.
When calling soapsuds for the desired webservice-class i get all my other methodes, but for the event i only get "add_xyevent"- and "remove_xyevent"-methodes. In the code in the example metioned above the event is subscribed inside the client like a regular event:
m_server.xyevent += new EventDelegate(handlerFuncion)
So i tried to use the event-method "add_xyevent", which ran into an SerializationException telling me that SOAP cannot serialize a generic type.
m_server.add_xyevent(handlerFuncion);
=> SerializationException
My question is:
How can i subscribe to this event?
Do i have to provide a specific keyword when declaring the event on the server?
Who can help me?
Thanks a lot!
J.

Anybody could help me how to get the internet speed provided by ISPs.It should be some thing like the pop up displayed on system tray in windows OS.
Thanks

You can get the connections and their connection speed, but that will only show the speed between your computer and the router. The actual theoritical maximum speed provided by the ISP is not possible to get.
Experience is the sum of all the mistakes you have done.

Hi all! I have to print a bar with its exact sizes. I used this code to generate a bar:
PrinterSettings ps = new PrinterSettings();<br />
Graphics g = ps.CreateMeasurementGraphics();<br />
IntPtr pHdc = g.GetHdc();<br />
<br />
mf = new Metafile(pHdc, EmfType.EmfOnly);<br />
<br />
g.ReleaseHdc(pHdc);<br />
g.Dispose();<br />
g = Graphics.FromImage(mf);<br />
<br />
g.PageUnit = GraphicsUnit.Millimeter;<br />
g.PageScale = 1;<br />
<br />
Brush b = Brushes.Black;<br />
<br />
g.FillRectangle(b, 0, 0, 2, 30);<br />
<br />
float dpix = g.DpiX;<br />
float dpiy = g.DpiY;<br />
<br />
g.Dispose();<br />
<br />
Bitmap bm = new Bitmap(mf, (int)(mf.Width / mf.HorizontalResolution * dpix),<br />
(int)(mf.Height / mf.VerticalResolution * dpiy));<br />
mf.Dispose();
Well, when I print the bm Bitmap I obtain a big bar on my page: it isn't 2x30 mm wide, but 12x188 mm wide!
Can you help me?
Thanks in advantage
