I must not know what you are asking for since I would guess you could figure that out for yourself.

or if you need room for a border:
myform.ClientSize = new Size(myusercontrol.width+some, myusercontrol.height+some);

Hi,
I am using dataset to bind to a datagridview. Data set have
Id,Name,Date,UserID ,UserName columns. The datagridview I have
column autogenerate property false and added ID,Name,UserName columns added
at design time.
Now question is, when I add a new row in datagridview, after entering value
for Name column, when i hit Enter Key, it shows me error that UserID can not
be null.
Could some one give me idea how to populate UserID value if its not
displayed on the datagridview.
Please guide me how to solve above problem.
Thanks in advance.

Hi i'm new to programming and I am coding in Visual C++ using windows forms but don't know how to call code in form1.h from another class.
I want the user to click on a button which will then will execute my code from the other class.
The form1.h does not like you to include any of the header file I have created and I don't know they are meant to be included somewhere else. I have included them in class where the main is created.
Not sure the other way as well, so if I created a new .cpp file and need to use say a textbox in the code. What needs to be done for this to happen?
Sorry for the stupid question

I see you post has been sitting unanswered for awhile. I would suggest you could get an answer if you asked it in the Managed C++ forum as most developers here are C# coders.
You also do not indicate if your other code is in another form or not. Typically you do not treat a form as a class. If you have code to be executed in two locations, then you create a class library and have both the form and your other code consume that class library with the shared code.
If your method needs to operate on a textbox, then just make it a parameter into the method call.
Hope this helps you some.

Hi I'm looking for a time line editor component, much like how Adobe Premier or those time line editing music tools. Is there such one around to recommend?
|
|
|
|

I have a dialog form which is currently showing. I would like to temporarily make it invisible. If I either call Hide(), or send a message to it to hide, then it returns a DialogResult. I'd like it to stay in the dialog loop - I'm going to make it visible again later.
Anybody have any advice?
Best wishes

Hi,
You may try using timer control and an integer/long type FLAG to achieve this instead of putting it in a loop. Below is the code snippet for the same. The below mentioned code consists of two forms Form1 (which is a main form) and a Dialog form (Dialog1)
-------------------------------------------------------------------------
BEGIN CODE
Public Class Form1
Dim FLAG As Integer = 0 ‘ Declaring a FLAG of integer Type
Dim frm As New Dialog1 ‘ Creatign an object of Dialog Form
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
‘ Setting the timer interval to 10 seconds.
Me.Timer1.Interval = 10000
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Timer1.Start()
frm.ShowDialog()
End Sub
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If FLAG < 32500 Then
If FLAG Mod 2 = 0 Then
frm.Hide() '
FLAG += 1
Else
frm.Show()
FLAG += 1
End If
End If
End Sub
End Class
END CODE
-------------------------------------------------------------------------
I hope this helps.
Have a nice day .

Hi,
AFAIK you can't do that. Forms shown with ShowDialog() will be hidden, not closed,
when a button or the close box is hit, so they can be reused later on.
Conversely, hiding a dialog corresponds to hitting the close box, hence returns
a DialogResult.
Rationale: a dialog is top-most, what good would it be to show the underlying form
but have it disabled (as dialogs do). Or more general, what is the use of an
invisible top-most window?

Hi Luc
I think you are right - that is the intention. Just for my application I'm trying to avoid this from happening.
You've asked why it would be of use - this, of course - stretches back to my application locking requirement which I am still working on.
With the windows forms source code released this morning I've been doing quite a bit of exploration. This is an excellent resource, and much better than reflector. I can't find exactly where the trigger that returns the DialogResult when the window when it is hidden (either with an external ShowWindow call, or with .net Hide/Show) - if I could I'd be able to see if there was any way to "work around" this behaviour.
Best wishes

Hi,
The behavior you have noticed is the default behavior of the grid. In order to implement the desired behavior you need to sub class the
DataGridView controls and override/overload ProcessDialogKey and ProcessDataGridViewKey functions. Below is the code snippet for the same.
-------------------------------------------------------------------------
BEGIN CODE
Public Class dgv
Inherits DataGridView
Protected Overloads Overrides Function ProcessDialogKey(ByVal keyData As Keys) As Boolean
Dim key As Keys = (keyData And Keys.KeyCode)
If key = Keys.Enter Then
Return Me.ProcessRightKey(keyData)
End If
Return MyBase.ProcessDialogKey(keyData)
End Function
Protected Overloads Overrides Function ProcessDataGridViewKey(ByVal e As KeyEventArgs) As Boolean
If e.KeyCode = Keys.Enter Then
Return Me.ProcessRightKey(e.KeyData)
End If
Return MyBase.ProcessDataGridViewKey(e)
End Function
End Class
END CODE
-------------------------------------------------------------------------

I'm trying to build a USB hub driver whose behavior is like windows' built in one.
My implementation is based on the ddk's example: toaster. Mass storage devices and scanners
works fine on my driver, however usb cameras can't be started.
I analysed the irps when the camera is plugined. After the start device irp, the driver received
a remove device irp. The ddk document says if anyone in the driver stack failed in start device irp,
pnp manager will send a remove device irp. I think there must be something wrong in the implementation before the remove device irp is sent.
There is a query interface irp which query TRANSLATOR_INTERFACE before the remove device irp is sent and I return STATUS_NO_SUPPORTED.
My response to start device irp is just like the toaster example does.
My question is:
1. Do I have to implement the TRANSLATOR_INTERFACE to fix the problem?
2. Or is there something else I have to do in my start device response?

CodeGuru has a hardware driver forum. You would probably get an answer over there.
Hardware-level development if a much different animal from standard application development.
Hope this helps you get an answer.
