Hello frends!
Im currently working on a simple web form when suddenly it hangs when i run it (1st time). I tried debuging but i dont think there's something wrong as it passes through Page Load. My Page Load doesnt do much xcept populate my 2 dropdownlists with texts and thats about it. Im scrapping through this one looking at web for designer, my html, even tried creating a new form with similar codes but it still hangs. Can someone pls help me...tnx so much!!!

Nevermind I found it...apparently in my html one of my dropdownlists was out of the <form> scope. Tanx!

Hi all
I working a Console Application.
I must hide Commmand prompt when start application.
How can i hide command prompt(dos prompt)?
Please,help me!!!
Thanks

You'll have to explain this better, because a Console Application can't run without the Console Window. What on earth do you mean by "hide the command prompt"?

Try executing prompt $s in the command line before running your application

I have created a ContextMenuHandler to show an additional menu item in the File Explorer when someone right clicks on a file (similar to winzips additions, or cut, or copy). This works fine. I actually followed an example from this site.
I added a registration function to additionally register the handler to work with Folders as well as files, so that when you right click a folder, it also shows the additional menu item. While this works under most conditions, the problem I am having is that the handler's IContextMenu.InvokeCommand() method is getting called when you click the Windows key + "e" (this brings up the file explorer normally). This is somehow preventing the file explorer from being launched at all when activated this way. I can still run the file explorer by navigating to it's shortcut, but it won't launch using the method I show above as long as I have my handler registered to add to the context menu for folders.
Any ideas?

Hi, anyone there, who knows a code snippet, in which a word doc document is converted to txt ?
I just want to extract the plain text of a doc and put it in a bytearray, without using external tools. I tested the "automating word" :
Link: http://www.dotnet247.com/247reference/msgs/26/131289.aspx[^]
But this doesn`t function with ASP ;(
I get a "access denied" Errormessage. I tried then to change the rights of the ASPNET User in dcomcnfg , but there is no "Microsoft Word Document" in DCOM ????
Anyone an idea ??
Thx
Hans.

i still have this " access denied" error ! I gave a lot of users full rights in the security tab:
Administrators
ASP.NET Machine Account
IWAM_Machinename
Interaktiv
IUSR_Machinename
everyone
System
But with no success...
I changed the identity from the user, who starts the application in my actual WinXP-useraccount...stilll the same error !!
No one there with an idea ?

Does BindingSource.Filter support wildcards? I have tried *,% and ? but none of them work.

Well always when you post a question you find the answer. I had to use LIKE instead of = when I used the wildcard (%).

Can you use framework 2.0 with visual studio 2003?
I just ran a bunch of service packs and installed framework 2.0.
Now, I open an C# web app and I get an error:
"Visual Studio .NET has detected that the specified web server is not running ASP.NET version 1.1."
"You will be unable to run ASP.NET web applications or services"
I did the aspnet_regiis.exe -i and thought that 2003 would be compatible. Am I wrong or is there something that I need to change in my solution or project file?
Thanks Much.
Will

No.
Visual Studio 2002 -> .NET 1.0
Visual Studio 2003 -> .NET 1.1
Visual Studio 2005 -> .NET 2.0
ONLY! No exceptions. You can't force 2003 to work with .NET 2.0. Remember, the compilers are built into the .NET Framework, not Visual Studio.

No. This question was asked so many times.
ASP.NET 2.0 installs a property sheet, so u can change the version of .net-framework.

What have I done wrong. I slapped up a quick dataset navigation control (first, back, next,last) to add to any form i create. somewhere along the line i have mangled something and now to update both the user control and the parent form (with it's databound controls) i need to add BOTH these two lines:
this.Parent.BindingContext[ControlDataSet, TableName].Position -= 1;
this.BindingContext[ControlDataSet, TableName].Position -= 1;
where : ControlDataSset is a DataSet on the parent form and TableName is a string containing the name of the table in the dataset I wish to move through
The VB version only requires the second line. It is incredible simple i am just stumped. here
thanks in advance

This is a little project i am working on nothing big.
Ok here goes, I have 2 forms my main form and my 2nd form my main form consists of a linkLabel once this linkLabel is selected it brings up my 2nd form (I could have used a button or menu but i chose linkLabel) I have the text for the 2nd form blank because what i want to do is once the 2nd form pops up i want it to contain the same text as the linkLabel. I know there is a way to do it just not sure how. i have been messing with this for the past couple days trying to get it to work.

In the link label click handler
void myLinkLabel_Click(object sender, EventArgs e)
{
Form2 myForm2 = new Form2();
myForm2.Text = myLinkLabel.Text;
myForm2.Show();
}

i tryed that, that happens to be the first thing i tryed
this is my linkLabel code
private void linkLabel1_LinkClicked(object sender, System.Windows.Forms.LinkLabelLinkClickedEventArgs e)
{
ItemsForm VIF = new ItemsForm();
VIF.ShowDialog();
}
and this is the error i get when i input ItemsForm.Text = linkLabel1.Text
An object reference is required for the nonstatic field, method, or property 'System.Windows.Forms.Control.Text
also the linkLabel name will be givin when the other parts of the program are activated such as the two listBoxes and radioButtons
Thanks.

Text is an instance property, not a static one - so you set Text on the instance that you created which was called VIF
private void linkLabel1_LinkClicked(object sender, System.Windows.Forms.LinkLabelLinkClickedEventArgs e)
{
ItemsForm VIF = new ItemsForm();
VIF.Text = linkLabel1.Text;
VIF.ShowDialog();
}

Thank you, i have tryed many ways and that is so simple i can not belive i did not find that.
thank you again.

ItemsForm.Text is trying to set a static property called text. You can only set the text on an instance of your ItemsForm.
private void linkLabel1_LinkClicked(object sender, System.Windows.Forms.LinkLabelLinkClickedEventArgs e)
{
ItemsForm VIF = new ItemsForm();
VIF.Text = linkLabel1.Text; // This will work, because you're setting the text of an ItemsForm instance, rather than on the ItemsForm class itself
VIF.ShowDialog();
}

Hi,
Anyone know why I'd get this error?
The type or namespace name 'CollectionEditor' could not be found (are you missing a using directive or an assembly reference?)
I do have using System.ComponentModel.Design; and then
private class CustomTableStylesCollectionEditor : CollectionEditor<br />
{<br />
public CustomTableStylesCollectionEditor(Type type):base(type)<br />
{<br />
} <br />
...<br />
} <br />
Thanks again!!!
Mel
