I have a transparent form (border style 0) that has no maximize button. Still when I double-click the window, it maximizes. Is there a way to prevent this happen when doubleclicking? And if there is a built-in keyboard combination in Windows XP to maximize windows, I would like to prevent that too.
Thanks!

Use the MinimumSize and MaximumSize properties (set them to the same value).

Thanks, but I have tried that. Window still gets maximized.
I have used this code to make my form movable:
Protected Overrides Sub WndProc(ByRef m As _
System.Windows.Forms.Message)
Const WmNcHitTest As Integer = &H84
Const HtCaption As Integer = 2
If m.Msg = WmNcHitTest Then
m.Result = New IntPtr(HtCaption)
Else
MyBase.WndProc(m)
End If
End Sub
Maybe there is the problem?

We're sorry, you caught us all on a Holiday Weekend, in the States anyway. It's very rude to demand an answer in a forum environment.

I'm wondering what you put in to make it do that. I put a little test project together, turned the FormBorderStyle to None (0) and can't duplicate the behavior you're talking about.

What's that piece of code supposed to do?
|
|
|
|

The border style is set to zero and the form is transparent. The code snippet I posted makes the form movable. When I double click the form it will maximized. This is strange.

I am working on Linux right now, so I cannot check this, but maybe you could try to set an appropriate size of your form in OnResized or OnMaximized (I guess that there are such events) event handlers.

Why not use plain old .NET code to make the form movable? You won't have this problem then.

Hello, I am new to writing console applications in VB.NET. I need some advice on how to get the little bit of text after the .exe /.
For example if I open a command window and type
program.exe /help or something like that
Or if you type
program.exe /? It will show help....
Thanks in advanced.

Hi,
use command line arguments!
command line arguments means the arguments you pass to your applications main() method.
hope this works.
Nitin...

Hmmmm, OK I know exactly what yo mean...
But how?
Thanks again

Your Sub Main can be changed to this:
Function Main(ByVal CmdArgs() As String) As Integer
Dim ArgNum As Integer ' Index of individual command-line argument.
If CmdArgs.Length > 0 Then ' See if there are any arguments.
For ArgNum = 0 To UBound(CmdArgs)
' Examine CmdArgs(ArgNum) for settings you need to handle.
Next ArgNum
End If
Return 0 ' Zero usually means successful completion.
End Function
You can find more information here[^].

Hi!
I'm using XMLTextReader and GetAttribute in order to parse a XML file. The problem is that the the file isn't 100% valid XML. File begins with many lines of "#####". My application works fine if I remove these lines from the file. But if I don't want to modify it, I keep getting error "Exception System.Xml.XmlException was thrown in debuggee: Data at the root level is invalid. Line 1, position 1."
Is there a way to write a code that doesn't mind these non-valid expression and manages to parse the attribute correctly?
With best regards,
RI

Hi,
Does anyone know how to do a search for files like in windows using vb.net.
thanks

Hello, I noticed your comment, and realised i had a similar need not so long ago, so i took it upon myself to create a program, which searches a chosen directory for a chosen file.
This program is basic and still glitchy, but should provide you with information you need on file searching. What is your email, so that i can email it to you.

I'm trying to save the image to sql database, there is error "object must implement Iconvertible" when I run it. Here is my code:
(image is the location + the name of the image)
Try
Dim strFn As String = image
Dim fiImage As FileInfo = New FileInfo(strFn)
Me.m_lImageFileLength = fiImage.Length
Dim fs As FileStream = New FileStream(strFn, FileMode.Open, FileAccess.Read, FileShare.Read)
m_barrImg = New Byte(Convert.ToInt32(Me.m_lImageFileLength)) {}
Dim iBytesRead As Integer = fs.Read(m_barrImg, 0, Convert.ToInt32(Me.m_lImageFileLength))
fs.Close()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
Try
Me.SqlConnection1.Open()
If SqlCommand1.Parameters.Count = 0 Then
Me.SqlCommand1.CommandText = "UPDATE HRRecordIndexData SET pdf_location = @Picture WHERE entity_id = @ID"
Me.SqlCommand1.Parameters.Add("@Picture", System.Data.SqlDbType.Image)
Me.SqlCommand1.Parameters.Add("@ID", System.Data.SqlDbType.Int, 4)
End If
Me.SqlCommand1.Parameters("@Picture").Value = Me.m_barrImg
Me.SqlCommand1.Parameters("@ID").Value = Entity
Me.SqlCommand1.ExecuteNonQuery()
Catch ex As Exception
MessageBox.Show(ex.Message)
Finally
Me.SqlConnection1.Close()
End Try
If there is everyone knows what it needs to fix at my code, I would very appreciate it .. thanks!

Lisa,
are you sure the field "pdf_location" has type "image"?
Regards

Hello, Ray,
I created another field called thumbnail and the datatype is image, and I run it again, the result is the same, it still gave me the same error.
thanks!

Hi,
I have similar code and it works.
The difference is only in parameter type definition :
System.Data.SqlDbType.VarBinary , not image.
Here is my code:
fv =me.openFileDialog1.FileName
Dim fs As New FileStream(fv, FileMode.OpenOrCreate, FileAccess.Read)
Dim MyData(fs.Length) As Byte
fs.Read(MyData, 0, CInt(fs.Length))
fs.Close()
kom.Connection=conn
kom.CommandText="INSERT INTO PDF (DATA,F_NAME) VALUES (@duom,@failas)"
dim param1 as New SqlParameter("@duom", System.Data.SqlDbType.VarBinary)
param1.Value=MyData
kom.Parameters.Add(param1)
dim param2 as New SqlParameter("@failas", System.Data.SqlDbType.VarChar )
param2.Value=fv
kom.Parameters.Add(param2)
conn.Open
dim res as Integer=kom.ExecuteNonQuery()

{vb .net 2003}
I'm working on creating a few side panels for my application that will slide in and slide out as needed. I have one docked on the left side, so it will resize with the window and still look the way I want it to. To "slide" it, I'm using a timer that decreases the width of it, making it look like its sliding out. I want to move all the controls in it (labels and picture boxes) to follow the sliding motion but I can't change the width without screwing up how the text looks, so I decrease the left value of the label as I decrease the width of the panel.
My question is this:
Is there a way to adjust the left property of all control in a panel at the same time without having to hardcode each individual label? I thought about doing a control array but then I would need seperate arrays for each type of element. Any idea?
Thanks for your time,
BAM

Instead of resizing the panel to make appear to slide, try changing it's location so that the panel slides off the left side of the form. The X portion of the Location can be in negative numbers and it should still work.

I tried changing panel1.location.x to a negative number and the panel won't budge. I think its because the panel is docked to that left side.
