Hello!
I am trying to create a UserControl which is inherited by Forms.Panel control
I have declared a variable for PictureBox as a class field
Friend WithEvents pb As PictureBox = New PictureBox()
After the InitializeComponent call in the default constructor, I have added the following code
pb.Visible = True
pb.Location = New Point(0, 0)
pb.Size = Me.Size
pb.BackColor = Color.Black
pb.SizeMode = PictureBoxSizeMode.StretchImage
Me.Controls.Add(pb)
Me.AutoScroll = True
I know that the PictureBox and Panel Control do not raise KeyUp,KeyDown, KeyPress events
Is there any way I can process KeyDown, KeyUp messages in this control?
Actually I want to process the KeyDown event for drawing a Rectangle then moving and resizing it using arrow keys over the picture box.
After the user finishes setting the rectangle, the user will press the Enter Key and the Image in the picture Box will be cropped according to the rectangle.
I have tried override the OnKeyDown but it doesn't invoke.
Thanking you in advance

Your control needs to have the keyboard focus in order to get the event.

Thank you for the reply
I have solved my problem by inheriting the ContainerControl instead of Panel.
(I hope it is good approach)
Thank You

hello guys:
i need help in mschartcontrol in vb6. actually i need help abt the plotting of the graph.i can feed values in the graph by declaring a 2D array and then using the chartdata property.
the problem is that the i have declared column count =1 and by right clicking the graph in the property window i have defined the series color RED.but when i plot the graph it plots in green color.
the second thing is that of the scaling of the y axis. i wish that the yaxis should show me the values up to 100. but when the program is executed it dislays the scaling according to the values given in the array.
can any body help me in this regard.
thanks.

Did you take a look at the ImageIndex[^] property of System.Windows.Forms.TreeNode?

Hello Waqas!
I think Crystal Report is the best solution. Though, I am not an expert in using Crystal Reports, but if you have any problem in using Crystal Reports then you can ask me.
You could also use the 3rd party tool (I liked this tool very much) is "Janus GridEx for .NET" and "Janus GridExPrintDocument"
Thank You.

I am trying to change the user-agent header sent by a web browser control in my application.
The method I used is catching the BeforeNavigation2 event fired by the control and stopping the request to change the header and finally re-send it. I keep getting a run-time error (80004005) that says the Method 'Navigate2' from the Web browser object failed. I can't figure out why this is. A curious thing is that when I add a message box before the Navigate2 method is called I don't get an error anymore. Could anyone tell me what am I doing wrong, or if another method of doing this exists.
Here is the code in my current event handler:
<br />
Private Sub Web2_BeforeNavigate2(ByVal pDisp As Object, ByRef URL As Variant, ByRef Flags As Variant, TargetFrameName As Variant, PostData As Variant, Headers As Variant, cancel As Boolean)<br />
Dim strMyHeaderField As String<br />
strMyHeaderField = "User-agent: XNBROWSER" & vbCrLf<br />
If InStr(Headers, "XNBROWSER") = 0 Then<br />
cancel = True<br />
Web2.Stop<br />
'MsgBox("X")<br />
Web2.Navigate2 URL, Flags, TargetFrameName, PostData, strMyHeaderField<br />
End If<br />
End Sub<br />
Thank you.

Just a guess, but try wrapping your code in a If statement that checks pDisp:
Private Sub Web2_BeforeNavigate2(ByVal pDisp As Object, ByRef URL As Variant, ByRef Flags As Variant, TargetFrameName As Variant, PostData As Variant, Headers As Variant, cancel As Boolean)
Dim strMyHeaderField As String
If pDisp Is Web2.Object Then
strMyHeaderField = "User-agent: XNBROWSER" & vbCrLf
If InStr(Headers, "XNBROWSER") = 0 Then
cancel = True
Web2.Stop
'MsgBox("X")
Web2.Navigate2 URL, Flags, TargetFrameName, PostData, strMyHeaderField
End If
End If
End Sub

It doesn't help. Still the same error. I suspect it may be something regarding the state of the Web browser object, which maybe it is changed after a short time ( time it takes me to click on the button of the message box). I don't know.

I'm creating aWindows Application Form with several textboxes.
How can I save all the textboxes to a file, so that I can re-use the informtion.
In the VB book they only talk about one textbox.
|
|
|
|
|
Just simple write all the textboxes to a file (remember using a delimiter. So that u can parse back the string read from the file)

It works fine on small databanks, by on large ones, I get an error. And this is the funny part about this. Windows displays the Error Report Dialog, says Faulting Application (Event ID 1000)., by the program will still keep running, and if I do not press anything on the Error dailog. My program will run to it all finish. If it is faulting, why does it keep on running? The following information is from my EventLog:
Faulting application egdatabanktool.exe, version 1.0.2126.24660, faulting module unknown, version 0.0.0.0, fault address 0x1f48cbc1.

One thing more, is that the fault address (0x1f48cbc1) will always be the same, and if the run this program on the different computer it will be different address but show the same one each time the error happens on it. By the way my computer is: XP Pro (SP1), Dell 2.79 GHz, Ram 1 GB, DotNet 1.1 (Not SP1), ADO 2.7
If you have any ideas, please let me know.

I want to be able to detect if a PC is connected to a network.
I found the following which I thought should work.
System.Windows.Forms.SystemInformation.Network
However it always returns true even with the Lan cable removed from my laptop. There is no WiFi. I even tried a re-boot with Lan cable removed.
As a test I tried
System.Windows.Forms.SystemInformation.Username
and this did work correctly so I ssume the class is working.
Anyone know why or is there an alternative solution.
thanks

Try using the Active DS Type Library, it has a few useful applications.

Thanks for replying and sorry for the delay.
Unfortunatley the network in question does not use Active directory.

Himanshu:
I have the same need to print a form. In Microsoft Access 2000 and higher, you can print a form exactly as it shows on the screen. I need to do the same in Visual Basic.net. Did you find out how?
