Re: Problem with controlbox

The controls are resizing themselves because that's their default behavior. Click on each control and, in the Properites window, look for the AutoSize property and change it to False.

The problem with this is that you run the risk of the controls new text exceeding the size of the control, cutting off portions of the text.

For more information on how it's normally done, see this[^] on MSDN.

Problem with controlbox

I have an app with several dialogs, that I have disabled the controlbox. Works fine on my development machine. However when I installed at a customer site, I found that the dialogs did not show properly - the lower 25% of the dialogs were 'cut off'. I checked the screen resolution, all machines have XP.

All the other windows show fine, just the ones without the controlbox are the problem.

Hi,

Perhaps you are facing the same problem I once encountered, when part of the controls on my form just fell outside the edge of the form on a certain PC, but not on any other.
On the problem PC, please check: Display Properties > Settings > Advanced > General > Display > DPI Setting.
In my case this was set to larger than Normal size (96 DPI). If this is the case for you too, just set it back to normal, and try your app.

Good luck,

Johan

My advice is free, and you may get what you paid for.

I discovered a common thread in the two windows that had probelms: I set controlbox to false.

Once I set the controlbox to true, the entire window was visible!

Thanks for the input.

How can I read a value from a XML file?

Here is my function. It opens XML file and reads a value that associated with a key. However, it is giving me "Invalid Operation" error. I couldn't figure out where the hack error is. XML file is residing under my currentdirectory where the application is. If you tell me the solution, I would really appreciate it. D'Oh! | :doh:

Private Function GetConfigParameter(ByVal MyKey As String) As String        
Dim XmlDocument As New XmlDocument        
Dim XmlNode As XmlNode = Nothing        
XmlDocument.Load(Environment.CurrentDirectory & "\app.con")        
XmlNode = XmlDocument.DocumentElement.SelectSingleNode_("//configuration/AppDefaultValues/add[@key=""" & MyKey & """]")
GetConfigParameter = XmlNode.Attributes.GetNamedItem("value").Value
XmlDocument = Nothing    
End Function

You can start by NOT naming your variables the same as class names, for example:

Dim XmlDocument As New XmlDocument

is a bad idea. This is because you can give yourself a headache wondering why the compiler is complaining about Static and Instance members, when your code looks correct.

Change the names to something less confusing...

Private Function GetConfigParameter(ByVal MyKey As String) As String
    Dim doc As New XmlDocument
    Dim node As XmlNode
 
    ' It's a bad idea to use CurrentDirectory, simply because the current directory
    ' can change during the execution of your app.
    doc.Load( Path.Combine(Application.StartupPath, "app.con") )
    node = doc.DocumentElement.SelectSingleNode("//configuration/AppDefaultValues/add[@key=""" & MyKey & """]")
    Return node.Attributes.GetNamedItem("value").Value
End Function

Use a Web Control in VB.NET

Hello,

Is it possible to use the GridView Component in VB.NET?
If yes how can I add it to my project?
Thank you,

Eric H.

Dave Kreskowiak20-Mar-07 4:42

Which version of VB.NET (.NET Framework) are you using? GridView showed up in the .NET Framework 2.0, and it should be in the ToolBox. You add it to your Web Form just like any other control.

Anything further and you'll have to provide more detail as to what the exact problem is.

I am using VB.NET (Framework 2.0)
The problem is this component is a web component. Therefore, I don't see it in the toolbox list. I tried to add it as a part of the toolbox but I didn't success.

If your writing a Windows Forms app, then it wont show in the ToolBox. GridView only works in an ASP.NET app. It's in the ToolBox under the Data tab ... or did I miss something in your posts??

Windows Forms uses the DataGridView. Again, under the Data tab in the ToolBox.

The Web has thousands of them. All you have to do is Google for "VB.NET DataGridView tutorial".

Use the Replace method of the String class, see [^].

You can't actually change a string. The Replace method returns a *new* string with the values changed.

Hi,
How can we get data or characters which is present on image.Actually i have captcha images in .JPEG extension and from that images i have to remove noise, extract the characters and then i have to convert the extracted characters in to string.So please give some idea how to proceed further.

Dave Kreskowiak20-Mar-07 4:39

20-Mar-07 4:39

There's a reason why it's noisy and distorted. It's so that you CAN'T use automation to get those characters!
