There seems to be hope! I have just gotten a System.ArgumentNullException in a LINQ call and the message is: Value cannot be null.
Parameter name: source Great! Now to fix it!

Hi,
I'm working on generating dynamically an assembly to let a user customize things. To do that, I used CSharpCodeProvider to generate the assembly and that worked fine till I encountered the problem of recognizing an instance created with the first version of the assembly after getting a second version.
So here are the steps I followed:
1- I generated an assembly containing a class called "Class_1" which just has an attribute called "Name".
2- I created instance of that and added it to a set.
For now, I can display all the item of the set (I used a main class Root which is created not dynamically and from which all the dynamic classes will inherit from).
3- I regenerated the assembly after adding "Class_2" which inherits from Root too and have a method that get as parameter a "Class_1" instance and that displays the name of the instance.
4- I created an instance of the second class and called its method with the "Class_1" instance that I created before. Doing that raised the following exception:
Object of type 'TestProject_CustomClassesLibrary.Class_1' cannot be converted to type 'TestProject_CustomClassesLibrary.Class_1'.
I searched on the net about that and I found multiple things:
* Signing the assembly the GAC but when I tried it, nothing changed.
* Using domain application but this require stopping the application each time we want to generate I guess (did not tried it by the way). So that's not a solution for me.
Is there any solution for that? What should I do to make this work?
Thanks for all.

Hi Guys,
I am running a command line application from inside my C# code, however it's failing and exiting out immediately. I'm trying to get the window to stay open after the program has finished running.
I've tried the following:
This opens the window, runs the script, fails and closes it:
Process.Start(@"C:\Program Files\Inno Setup 5\iscc.exe", @"%dir%\MyInstallScript.iss");
This opens the window, keeps it open, and says: 'C:\Program' is not recognized as an internal or external command, operable program or batch file.:
Process.Start("cmd.exe", "/k \"C:\\Program Files\\Inno Setup 5\\iscc.exe\" \"%dir%\\MyInstallScript.iss\"");
Second one seems a bit weird, as i am wrapping everything in quotes as expected. Not sure what's going on here. Do i need to do something crazy like nesting the quotes? And if so, how would i do that? Any thoughts?
Regards
Tris

Hi,
This looks straightforward but like you I cannot get it to work. I read the MSDN page on cmd.exe and the section on processing quotation marks left me completely baffled.
http://technet.microsoft.com/en-us/library/bb490880.aspx[^]
As with much of the stuff on MSDN it is missing a decent example. Can you understand what the /s switch does? May be I'm just thick but I don't think "Modifies the treatment of string after /c or /k" is an explanation.
A simple solution or workaround for your problem would be to start a batch file, e.g.
Process.Start("setup.cmd", "\"%dir%\\MyInstallScript.iss\"");
where setup.cmd is
@echo off
C:\Program Files\Inno Setup 5\iscc.exe "%~1"
pause
If you are concerned that the batch file could be modified by the user you could always have your program generate it just before it is required.
Alan.

The entire command line after /k needs to be in quotes like so:
Process.Start("cmd.exe", "/k \"\"C:\\Program Files\\Inno Setup 5\\iscc.exe\" \"%dir%\\MyInstallScript.iss\"\"");
Note the extra quote characters at the start and the end of the argument after /k.
Eagles my fly, but weasels don't get sucked into jet engines.

Oh I get it,
I would never have thought of trying out that many quotes although after unescaping everything it is clear that there is now only one string after the /k.
cmd.exe /k ""C:\Program Files\Inno Setup 5\iscc.exe" "%dir%\MyInstallScript.iss""
Alan.

how to autoposition controls like label,hyperlink etc in visual studio 2008.I am able to enable the autopositioning options for textbox,button etc
|
|

Docking won't work for labels, until you set AutoSize to "False".

I have an event handler with three local variables defined, all of which are strings.
When I set a breakpoint on the first item, and try to step through the code, the debugger jumps completely over these two lines:
string tableName = "";
string fieldName = "";
If I try to set a watch on them, the watch window reports that they're not part of the current context.
I've tried creating a new method, renaming the vars to something guaranteed to be unique in the app, shutting the IDE down, unloading/reloading the project, and taking out everything but those two lines of code. Nothing has solved the issue.
EDIT --------------------------
I was compiling to "Any CPU", and I was supposed to be compiling to "X86" (it's a ODBC driver thing). Changed it to X86, and everything is fine now (that means I'm back to more understandable defects in the code).

I've had that happen before too. I just Cleaned the solution and rebuilt everything.

That was the first thing I tried...

Well, the variables *are* being used, and I can define and break on unused variables all day.

I am using the Winform's WebBrowser control to display HTML documents in my application. Now I need to draw a line above a certain HTML element in the document, and I'm hitting a road blocks.
First, I tried to simply paint a line above the element, but quickly found that the WebBrowser doesn't support the paint event.
Next, I tried to just position a thin, "line-like" control above the HTML element. I know the position of the element within the document, but to position the control properly, I'd need the WebBrowser scroll position. I'm reading that you can't read the scroll position, or receive scroll events from the WebBrowser control.
Anyone have a plan C?
Thanks,
Aaron

I've run into a similar problem recently. My plan C was to modify the html and use WebBrowser.DocumentText.
I also wrote this, which might be useful:
private void SaveScrollPosition()
{
if ( Loading ) return;
var document = _Control.Document;
if ( document == null ) return;
var body = document.Body;
if ( body == null ) return;
if ( body.ScrollLeft != 0 || body.ScrollTop != 0 )
{
ScrollPositionX = body.ScrollLeft;
ScrollPositionY = body.ScrollTop;
return;
}
var htmls = document.GetElementsByTagName( "HTML" );
if ( htmls == null ) return;
if ( htmls.Count == 0 ) return;
var html = htmls[ 0 ];
if ( html == null ) return;
if ( html.ScrollLeft != 0 || html.ScrollTop != 0 )
{
ScrollPositionX = html.ScrollLeft;
ScrollPositionY = html.ScrollTop;
return;
}
}

We need to package a windows application(C#) as an installable and during the installation by the user we need to get details about the different servers like Database server name or IP and test if the server exists. If we use the standard Setup in .net we are not able to customize it as we want ,i.e. we are not able to write any code for testing the user inputs. Please Advice . TIA

You would better use third party product like Installshield for that.Customizing Windows Installer is not simple at all.

Hi all.
I need to create a plugin that use a similar Visual Programming Language interface of Rhino3D Grasshopper, LabView or Ms Robotics Developer Studio GUI, but I haven't found anything on the web.
If there is an open source project like it, I couldn't rewrite the VPL from scratch.
Someone knows something similar project? 
Thanks for all!!
