Start by an english book first than go and get a C# book.

bitter truth 
most e-books are in english..

A beginners book, then work through examples on this site and ask questions here.
Try to get a C# language book, then a book that works with windows forms after that. A book that tells you where to click so the designer writes code for you, is useless.

hello there buddy!
Welcome to the world of C#!
Get a book on C# language, and start working on examples.
Think of something innovative and try implementing it.

Hi,
this is my first question on CodeProject; its about Visual Designer.
Say I want to have a Panel and a PictureBox in the Form, no problem.
Now a Button in that Panel, no problem, just click in the Panel and drag a Button.
Now a Label in that PictureBox, Designer does not do that, even when I click inside
the PictureBox, the Label gets added to the Form, not to the PictureBox
(code checked: parent is Form, location is Form relative).
Also not working is Button in Button.
Is there a way to do these with Designer, i.e. without changing the code manually ?
If it is impossible for some Controls, which are they ? How can one recognize them ?
I am using both Visual 7.1 and 8.0 (in case it would be different).
TIA

I only VS .net
Some controls are not containers.

I think you cannot recognize them. For example, the GroupBox and PictureBox are both direct inheritors of Control, but a dragged control is only added to the group box. So the designer is obviously following his own logic where it is sensible to add the dragged control to the form or the control it was dragged to, respectively.

Hello Luc,
Isn't the interface "IContainer" responsible for that behavior?
All the best,

i'm using devenv to compile projects
say
Process.start("devenv",@"<solution> /build Debug ........... /out C:\BuildLog.txt");
the next piece of code is:
StreamReader sr = new StreamReader("C:\\BuildLog.txt");
string line;
while((line = sr.ReadLine()) != null)
{
LogText += line;
}
this throws a filenotfound exception the first time. on running the application again, it finds the file and displays its contents too...
the file gets appended with every run. but on reading it thru this code it does not read the latest chunks written to file.
for eg say
the file contains
abc
xyz
def
the file reads only abc xyz
and the next time it runs it reads abc xyz as well as def... but by then.... more chunks r appended.
Kindly help.
thanks in advance.

You must have code that is creating this file, so that the next time it runs OK. Does your write code rewrite the entire file, or just append to it ?

thanks for replying.
the file is automatically created as the application is compiled
devenv .....(args...) /out c:\\BuildLog.txt
creates/appends the file buildlog.txt
i don't write anything to this file at all. i just need to read it and display all of its contents.
thanks and regards,

My app has a CheckedListBox, after added items, not be able to gray out some items so users can't select them.
Any one has solution?
Thank you.

I don't think it's possible to do without some custom drawing. You might try overriding OnPaint and see if you can do some drawing in there to manually gray out a particular item.

OK I tried to double chech (5 times at least acctually) all things, still when I replace
this code:
<code> HttpChannel c = new HttpChannel(32469);
ChannelServices.RegisterChannel(c);
RemotingConfiguration.RegisterWellKnownServiceType(
typeof(SimpleChatProgram_DLL.SimpleChatProgramLibrary),
"RemoteMsgObj.soap", WellKnownObjectMode.Singleton);</code>
with this one
<code> RemotingConfiguration.Configure("App.config", false);</code>
and
this config file:
<code><configuration>
<system.runtime.remoting>
<application>
<service>
<wellknown
mode="Singleton"
type="SimpleChatProgram_DLL.SimpleChatProgramLibrary, SimpleChatProgram_DLL"
objectUri="RemoteMsgObj.soap"/>
</service>
<channels>
<channel ref="http" port="32469" />
</channels>
</application>
</system.runtime.remoting>
</configuration></code>
my client app (very simple program btw), stop working it can't even start anymore...
Server start just as usual, but doesn't work as expected...
Any idea?

Any idea guys, I tried bunch of mine, but none give expected results, guess it's something trivial..

try the filters ... unfortunately i forgot the right syntax, but it have something to do with soap or binaryfilter...
<channels>
<channel ref="http" useDefaultCredentials="true" port="0">
<clientProviders>
<formatter ref="soap" typeFilterLevel="Full"/>
</clientProviders>
<serverProviders>
<formatter ref="soap" typeFilterLevel="Full"/>
</serverProviders>
</channel>
</channels>
i cut/copy this from my own project, maybe it helps you

I've recently come over to VS/C# from Delphi, and I know this is a basic question, but I am seemingly wading through far too much documentation to find the answer.
I want to use a struct or Object as a property of a component. In Delphi, any such property declaration automatically resulted in an expandable node in the IDE, displaying all the properties of the struct or Object within the root component.
I see in the VS library documentation now that structs such as Size and Rectangle do expose themselves to the IDE by way of editors. I have not written whatever required editor, but without the editor, my struct or Object property appears as grayed out text in the Property window. I believe I've properly set up the attributes for my intended property. But in any case, I cannot edit the struct or Object property in the Properties window.
Can anyone just confirm for me that indeed I do (or do not) have to write an editor, and perhaps point me toward what kind of editor to write, and what VS documentation to see for reference?
Much thanks in advance,
mike

That doesn't happen here. You can use attributes to make a property appear in the designer, and if it's a struct, you could mark those properties as well. I think it's [Browsable].
The real question is, why do you need to set it in the designer ? But, I believe the problem is, the designer knows nothing about your struct, you need to set it up to expose the properties of the struct.

Setting the Browsable attribute hasn't seemed to be enough. I will try setting up the designer and report the results when I get around to that (hopefully later today).
Thanks, Christian.
