OnKeyDown in modeless form
I have an application that displays a modeless form. On this form i
want to trap certain keys. For example ctrl-right, ctrl-left, ...
I have these keys already working on the main form of my application,
but know i need to trap them in a seperated modeless form, but the
onkeydown event is not being fired.
How do i go about trapping these keys. Tag: Looking of Free and facny treeview control Tag: 81239
Multiple minimize and maximize buttons appering on MDI menu contro
Below is text of the simillar problem we are facing allready posted by
another user on the net...
I have created an MDI application. When the first child form is opened and
maximized one set of minimize, restore and close buttons are displayed on the
menu bar. After closing the child window a set of minimize, restore and close
buttons remain even though the child form has been closed.
EXAMPLE:
http://novasolution.net/Error2-2.jpg
When a second set child form is opened and closed a second set of minimize,
restore and close are shown on the menu bar.
Each time a child form is opened and closed, another set of controls appears
on the menu bar. When I open a new child form the multiple sets of buttons
disappear. When the child form is maximized, only one set of buttons displays
in the menu bar. When the child window is closed another set of buttons is
displayed on the menu bar.
some how we are unbale find a solution to this problem..
Any ideas..

Forms pseudo MDI support
While trying to implement a MDI Application I found that the Windows.Forms
classes that implement this functionality don't actually use the WIN32 MDI
API.
Using Spy++ I found that the MdiClient class does not use the 'MDICLIENT'
window class. I also hooked up a Messagefilter to look at the MDI messages
send to the mdiclient, the only messages I saw were WM_MDISETMENU and
WM_MDIREFRESHMENU.
Can anyone confirm this or does anyone know why this was done? Tag: Looking of Free and facny treeview control Tag: 81233
UPDATE SQLTABELLE
VS2003 C#
Ich habe einen SQLDATAADAPTER erstellt und ein DATSET generiert.
Diese Dataset stelle ich in einem DATAGRID dar.
In der Tabelle ist das Feld UKID als Primärschlüssel definiert und damit
werden keine Nullwerte zugelassen.
Num füge ich im DATAGRID einen Satz hinzu und update den
SQLDATAADAPTER(DATASET).
Die neuen Sätze stehen in der SQl-Tabelle.
Nun möchte ich aber im DATAGRID das Feld UKID (Primärschlüssel) nicht mit
anzeigen und somit
bei kann ich bei einem neuen Satz auch keinen Wert im DATAGRID dafür
eintragen.
Betätige ich dann den Button zum Update des SQLDATAADAPTERS
erhalte ich folgende Fehlermeldung "Spalte UKID läßt keine Nullen zu ..."
Wie kann ich dem Feld UKID einen Wert im Code zuweisen, damit ein neuer Satz
im DATAGRID
akzeptiert wird?
Das heist, der Nutzer soll bei einem neuen Satz im DATAGRID nicht die UKID
eintragen können,
die soll im Programmcode mit einem Wert belegt werden.

Control layout problem with system large fonts
I have seen many people stating that they have the same problem.
I have the font DPI setting set to 125% normal size (from the Display
Properties dialog when you right-click on the Desktop). If a Windows
Form is more than simle (has many controls), then the most chance is
that when the Form is shown in runtime, the layout is somewhat in right
condition (Some controls might position beyond the visible client area).
I am not sure if Microsoft noticed this problem. I think it is a very
*BAD* problem, based on that Microsoft/Windows have been strong in user
friendly GUI since their beginning.

Threading
Hello,
I am making a app that creates a thread to show a clipboard. If the
clipboard is double clicked, another window is displayed, the event is
handled inside the main app. What I would like to do is have the clipboard
use the main thread of the application that called it to handle the new
window. Is this possible and if so how would this be accomplished.
ie.
Form1 creates a thread and the thread displays Form2.
Form2 when double clicked raises an event that creates a new form (Form3).
The event is handled inside Form1.
How can I get Form3 to be managed by the main thread (Form1)?
Thanks,

Auto Expanding TextBox/Controls
Hi there,
I've googled this problem, and not found a suitable solution yet. I was
wondering if anyone has made any progress?
Basically, I want to make a textbox automagically adjust it's height to show
all the text it contains. So, if I add text then it grows, and it shrinks if
I remove text. This is similar to the CanGrow property in MS Access
controls.
I'm willing to purchase a control if anyone knows of any, I'd just like to
get this cracked without spending *too* much time "fiddling" about!
Any help much appreciated

Add user control to winforms Toolbox
I created a user control which I signed and added to GAC. Users add the
control to the toolbox by navigating to the dll.
However when they drag and drop the control from the toolbox onto the
winform they get an error, which basically means they need to manually add
references to other dlls which are referenced by my user control dll.
Is there a solution to this? Thank you Tag: Looking of Free and facny treeview control Tag: 81214

User Control's Load event fires when the Dispose method executes
I have a user control which is used as a data entry form and it is
instantiated on a window form. When the windows form is closed via clicking
on the top right red-X close button, the user control's Dispose method
executes. When it executes the load event fires.
Here's the dispose method:
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
'WHEN THE NEXT LINE EXECUTES, the controls Load Event Fires.
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub
This user control also created instances of some other user controls used as
sub-forms. I don't know if this has anything to do with it, but when the
user clicks on the red-X close button of the parent form and things began
to close, no cleanup code ran to kill the instances of these user controls.
I will eventually have the proper cleanup code in place, but right now I
want to understand why this load event fires when "components.Dispose()" is
called.
Thanks.

DateTime Bound to TextBox
Hi,
I have bound a DateTime field in a DataTable to a TextBox field. Other
String and Numeric fields are also bound to separate TextBoxes. If a new
DataRow is created and a DateTime value is entered no problem. However,
after the row is saved, I am unable to clear the date from the textbox.
I do not have this problem when binding to a DataGrid. But a DataGrid is
far from user friendly and just plain impractical in many situations.
In its place I am loading the DataRow into a class and using unbound fields
on the form. Bound controls seem great for strings. But thats about it.
Does anyone have a better solution?

How to simply load a freeekin bitmap from a resource?
I'm coming over from a background in VC++, and in general I've been
pleased with the simplicity of the .NET environment. Not here.
I've done google searches on this subject (loading bitmaps from a local
resource) and always come up with complex solutions. This can't be right.
Everyone packs bitmaps and other graphics and resources, integral to small
executables, right?
Setting up a local resource folder, loading in graphics, and setting their
properties to 'Embedded Resource' would seem to incorporate them, as
expected.
Then what? It's tough to make 'FromResource' happy. There's got to be
some simple solution to this. Tag: Looking of Free and facny treeview control Tag: 81191

Deployed simple C#.NET single form application to Windows server 2003 and the form will not display, but application appears in the the task bar.
I have a very simple C#.NET (Framework 1.1) application that is one form
with standard .NET controls on it. The application requires a CONFIG file
to work. When I install the application to Windows 98/2000/XP, I simply
install the .NET framework and copy the EXE and CONFIG files to the
workstation and double-click the EXE. This has worked fine for those
Operating Systems. When I deployed this to a Windows Server 2000 machine, I
just needed to do the same to get it to work (.Net was already installed).
However, when I copy the EXE and CONFIG file to the Windows Server 2003
machine and double click the EXE, the form does not display any User
Interface (the single form), however, an application block appears in the
Task Bar (toolbar that contains the start button and system tray). I do not
know what is causing this, and I have no idea how to fix this. I have
searched the Microsoft Knowledgebase and googled some searches, but have
found no information that has been helpful. I have tried to use the
"Microsoft .NET Framework 1.1 Configuration" tool, but no luck. Any ideas
or suggestions?

ScrollableControl Scrolling by Itself
I have a UserControl with AutoScroll set to true. When my application loses
then regains focus, the control scrolls itself to make ActiveControl visible.
This also happens when I dynamically add or remove child controls. Is there

Here's some sample code demonstrating my problem. Run the application then
scroll down and right as far as possible. Button one will be scrolled out of
view and button two will be visible. Switch to another program then come back.
The scrollbars will move to make button one visible again.

Hidding a window and preventing Alt-Tabbing to it
I'm trying to hide the main form of my application, as I want all of the
user interaction with my application to come from interacting with a notify
icon with a context menu in the system tray (which I have working). I've
figured out how to hide the form easy enough, set the WindowState to
Minimized and ShowInTaskbar to False.
What I can't figure out is how to prevent the user Alt-Tabbing to the
window, as its still visible in the Alt-Tab menu. I can set the windows
FormBorderStyle to FixedToolWindow or SizeableToolWindow and it will no
longer show up in the Alt-Tab menu but now it will now minimize to the
bottom left of the desktop just showing the windows title bar instead of
being completely hidden!
Does anyone know of any way to completely hide a window visibly(so no part
of the window is visible anywhere), with no icon on the task bar or on the
Alt-Tab menu? All I really want is to be able to run a notify icon in the
system tray and a context menu for the icon but I'm don't know of any other
way to do it other than to run it in a enclosing form.
I've been wondering if making my application a service make things easier
but I've no experience with programming services and it seems a bit of
overkill for what I'm wanting to do!
Any advice would be most appreciated!

Hello, Japan?
My application is so successful that it needs to go global.
The only problem is that that means Japanese. I don't know the first thing
about making a Japanese language application. I know I have to use Unicode,
but that's about it.
In case it matters, the user will be presented with a dialog, and he can
choose, dynamically, which language it should be rendered in. So, it isn't a
matter of linking a particular resource file for Japanese on one machine, and
a different one for English on a different machine. Both must be available,
based on user choice.
Is there a simple "Hello, World" application for the .Net framework, but in
Japanese? Or any sample applications that make use of Japanese? I don't
even know where to find a Japanese font.

Panel & keyboard focus
I have a panel and some of my controls on it (each control is derived from
Control, not from UserControl). I need to delete the selected control by
pressing the Del key. How it can be done? Panel does not process any
keyboard events. Also I don't want to delete any controls when focus is on
the other controls of the form.
So the scenario is something like this:
1. User clicks on some of my controls (panel receives focus)
2. User press Del key (control removes from panel)
3. User press Tab key (the focus is received by another control of the form,
but not a control of the panel)
4. User press Del key (nothing happens)
So the main question is how can I monitor focus state of the panel and
process the keygboard input?
Thank you very much.

create object dynamically
hi guys,
i just have a doubt about this one... i have several class that just
basically do CRUD operations (create, read, update, delete) now for example
on my delete function, i want to create objects dynamically based on
TableName..
this is my current line of code
Public Sub ActionButton_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs)
Select Case TableName.ToLower
Case "employee"
Dim o As New BusinessLogic.EmployeeController
o.Delete(1)
Case "gender"
Dim o As New BusinessLogic.GenderController
o.Delete(1)
Case "more of this on my code"
Dim o As New BusinessLogic.[other]Controller
o.Delete(1)
End Select
End Sub
now i want to make this line of code shorter, maybe by doing this
Public Sub ActionButton_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs)
Dim o As New BusinessLogic.[TableName]Controller
o.Delete(1)
End Select
End Sub
note the [TableName] here is a property i created, so passing a EMPLOYEE as
the TableName will
Dim o As New BusinessLogic.EmployeeController and then i can call the delete
function, just want to load object dynamically here.. i hope i made my point
here clear...
is it anyway possible?
TIA!

Mouse event handlers
I am writing a 3D graphics demo for my students, and thought I had a really
slick solution for handling the interaction with the mouse. There are
several ways to interact with a 3D world, and I have attached a mouseDown
event handler to my OpenGL panel (control). What I want to do, is based upon
which mouse button was pressed associate the proper mouseMove event handler
with the control. OK, so I have a From with several controls, including a
few OpenGL controls I created. I attached the mousedown to an OpenGL
control. In the callback I want to associate the MouseMove and MouseUp event
handlers. I first tried something like this in the MouseDown event handler:
m_MouseMoveDelegate = new MouseEventHandler( camera.Trackball );
this.MouseMove += m_MouseMoveDelegate;
m_MouseUpDelegate = new MouseEventHandler( My_MouseUp );
this.MouseUp += m_MouseUpDelegate;
This associates the mouse handlers with the entire Form though, not the
control. I am rather clueless on the sender semantics. I tried casting it to
my UserControl (OpenGLPanel), but that led to very bad behavior. Not sure
why. I also need to retained the mouse position of the mouse down event.
The problem above is either the "this" identifiers, or trying to save the
mouse position from the mouse down event. Casting this to screen space
provides somewhat better behavior, but not ideal.
Questions:
1) Is there something fundamentally wrong with this design?
2) Is the sender one of the controls I registered the MouseDown event
handler to?
3) In particular, is it the control in which I pressed the mouse?
4) Can I associate a MouseMove event to the sender? Note, I do not want to
embed my form logic in here and test for which control, etc.
FYI. The mouseUp event simply removes the event handlers:
// Disconnect the MouseEventHandler
this.MouseMove -= m_MouseMoveDelegate;
this.MouseUp -= m_MouseUpDelegate; Tag: Looking of Free and facny treeview control Tag: 81122
Getting the keyboard state in MouseMove
In my windows app, I have an event handler for the mouse move, and want to
allow for constrained interaction using the shift or control keys. I can not
figure out how to get the state of the shift, control or alt key modifiers
for the mouse. The mouseEventArgs does not seems to have anything, and
casting the sender to a control and trying to inquire has led to compiler
errors. This functionality exists in the Drag and Drop event args, but not
the mouse. How do we determine the key modifiers for the mouse in .NET?

How can I custom draw a window title bar
Hi All
I've tried without success on google and google groups to find the answer to
this, but without success - but I do recall it being discussed...
In my application, if I want a slightly modified Title Bar on some forms -
eg so that it is coloured yellow rather than using the system scheme, is
there a way that I can do this? I know I could do FormBorderStyle = None, and
draw my own window including my own title bar (lots of references how to do
this). But I don't want that (well if it's what I have to do, then I guess I
will!) I just want a standard title bar with a different colour.
Any ideas?

how to drag from RichTextBox?
hi all
when i drag from my
RichTextBox to any other control
in windows,
it works nice.
however,
if i mark it as 'readonly= true'
then it does NOT work.
that is, on the first drag operation.
in the second drag operation and
all proceeding drag operations,
it works nice.
however,
this is only true if i set the
RichTextBox to be
'readonly= true' at runtime.
if i change it to be 'readonly= true'
at design time.
IT NEVER EVER allows drag
to succeed!
this seems to me to be an
authentic bug in the dot net/
visual studio.
has someone else experienced this problem?
is there work-around?

Dynamic Properties. What the point?
I have been playing around with the "Dynamic Properties" of the controls and
for the life of me, I can't figure out why would anybody care about using
feature.
It looks like the only things that this feature does is store and retrieve
values from the app.config file! The thing is that, there is already a way
to do this during runtime!! In fact, that's what happens once the app starts
running under "Windows Form Designer generated code"!!
Other than just some kind of time saver (arguably) is there something that
I am missing here, is there some big benefit on using this feature that I
don't know about?
Thank you. Tag: Looking of Free and facny treeview control Tag: 81110
