How to use a custom font
Hi !
I wonder how I can change the font of a .NET C# application ? I have a
".ttf", I suppose it's a TrueType font file. I will appreciate any help, if
you have tutorials it will be great too.
Should I copy it to Windows System folder ?
Thanks in advance,
Regards.

Disable focus on webBrowser control
Hi all,
I dynamically load a webBrowser control on a windows form control. Every
time I load the webBrowser control the focus is set to the webBrowser control.
How can the focus be set to another control on the form, after the
webBrowser control is loaded?

how to set application-wide keyboard handling?
hi all
i have a 2 winforms in my app.
one is the owner of the other.
i capture keyboard events for
each form.
can i instead tell the entire 'app'
to respond to certain keys.
and not have to tell each form to handle the keys.
i actually have over 20 forms,
so handling keys for each form
would be a lot of dirty work.

Building a windows forms "spy"
Hi
I am about to develop a program that scans the text properties of a number
of text boxes in another program and copies them to the clipboard. The
software that I want to scan has no function for printing on a printer, and
therefore I am building this extension to enable simple printouts.
The program I am scanning is built in C#. My program should be built in C#
too.
I do not know the names of the textboxes, so to begin with I need to be able
to get the names of the textboxes to scan. These names will probably not
change, so when have gotten these names I can add them to the code. I know
the name of the form (or at least the caption of the form) that the
textboxes are in. I have no need for changing the properties of the
textboxes either.
Does anyone have some simple code that can help me getting started?
Thanks

Question about printing
Dear all,
I'm new in printing in VB.NET 2003 and want to print a run-time generated
form which contains line drawing shape and text. I found that PrintDocument
is good for printing by code but not for entire form. Actually it is not a
kind of report but label sticker so I don't think Crystal Report is my
choice. Does anybody have idea on my issue?
Thanks for your attention and kindly help!

Help!!! Visual Inheritance......
Hi,
I want to know if I'm doing something wrong. I'm inheriting frmChild
from frmBase in Project1. frmBase is referring to its MdiParent in a function
call from Form_Resize event. When I try to open the designer for the frmChild
it throws an exception for this, saying "Object reference not set to an
instance of an object."
Why is this happening. Does that mean I cannot use any runtime
instanciation in a base form? Or do I have to turn something off? Why is the
code executing in the designer. If I give a message box in the base form, it
pops up when I am loading the Child form!!!!!
Any help is appreciated..

Why does transparency only work sometimes with 32 bit color depth?
I have an application that uses transparency. My video settings are
1600x1200 and 32 bit color. I can make the main dialog transparent but
other controls and child windows are not transparent, I see the colored box
around my control. If I switch my color depth to 16 bit everything is fine.
Why does it work on some forms but not others.
I can even make my main form transparent and drop a custom control that has
transparency set. The main form goes transparent but the custom control has
a blue (my transparent color) box around it. Again if I switch color depth
it works fine.
I heard that somewhere in the .NET documentation it says transparency is not
supported under 32 bit color. I have a hard time believing this. Are there
any computers that don't come in 32 bit color mode anymore?

Memory leak - Forms with Owners
I have created a project that has two forms. Form1 has a button which
runs the following code:
private void button1_Click(object sender, System.EventArgs e)
{
Form2 f = new Form2();
f.Owner = this;
f.Show();
f.Close();
this.RemoveOwnedForm(f);
f.Dispose();
f = null;
}
Using .NET Memory Profiler (http://www.scitech.se/memprofiler) I am able
to see that Form2 is not disposed. This seems to be a huge issue. Has
anyone experienced this problem? Is there a workaround? Have I done
something incorrectly?
If I remove the line where the Owner is set, there is no problem with
Form2 being Disposed.

exceptionless exceptions in masked edit box
Hello,
I encountered something to that, even though I have worked it out for
myself, I thought should be passed on.
While I was debugging an event handler (Validating) for a masked edit
box, I suddenly found myself 'back in the UI'. The line of code that
precipitated the surprise exit from the event handler to the UI happened to
generate a null reference exception, but no detectable exception was reported
(either in the IDE debug run or in the released program).
The line of code was not in a try/catch block (there are others in the
handler and, when appropriate, they are triggered). It was the true source
of the bug being worked on, but it was not detected until much later in the
code because as far as anyone knew the event handler validated the control
quite nicely.
I figure that whatever 'hidden' code calls the event handler does so from
within its own try/catch block. When it encounterd this particular
exception, it simply returned execution to the 'UI thread' (no explicit
multi-threading was used in the program, that descriptive phrase was intended
to limit verbiage (looks like I failed there)).
I don't know if this is just an issue with the masked edit box or with
more controls.
Thought you'd like to know,

Global connection strings?

multiple forms each of which stores a connection string back to (generally
speaking) the same SQL db (i.e. it's set up the way that VS.Net appears to

drawing text, autosizing textbox, flickering ...
Hi (VS.Net 2003 + SP),
how to make anchored textboxes, toolbars or statusbar not to flicker on
resize?
And one more thing, I wanted to make multiline textbox to autosize in height
and width. Since autosizing is done only in singleline, I used
prefferedSize= Graphics.MeasureString(control.text, control.font)
to get required size. But after resizing textbox, I saw that it is too wide
and height is less than required. So I tried to paint text myself. Then I
saw, that everyline of that text is painted differently (using standart font,
same text on every line), changing text to Arial 9pt, helped a bit. But
anyway it is too wide and height is less than required for textbox. How to
implement full autosizing for textbox? Tag: Custom datagrid Tag: 78951

Form transparency issues
Recently I wanted to create a small little program that could sit=
on the desktop and not block the desktop wallpaper=2E There are=
two methods to accomplish this ( that I am aware of )=2E
1) create a solid color bmp as a background image and set the=
transparency key to match its color
2) specify the form's background color with a matching=
transparency key
Now my issues with both methods, but first it should be known=
that I have set the forms to have no border or title bar and=
have implemented code that allows me to click-and-hold anywhere=
( with exceptions listed below ) on the form and move it=2E The=
data actually displayed on the form is just text and one=
rectangle, all drawn by me ( there are no controls on the form=
itself )=2E
1) I have two issues with this method, although it is what I'm=
prefering to use at the moment=2E The first seems to be the=
discrepancy between how the program is handled when the=
computer's Color Depth is 32bit or when it is less than 32bit (=
16bit )=2E When the color depth is 32bit then I am able to click=
on the entire area the form inhabits ( even that which is=
transparent ) and move it, but if the color depth is less than=
32bit ( 16bit ) then only the drawn text or rectangle outline (=
since it has no fill ) can be clicked to drag the program=
around=2E Clicking on the transparent areas just passes the click=
through the form to whatever is below ( even when I know the=
form has focus )=2E I'd like to be able, regardless of the=
desktop's color depth, to click anywhere within the form area=
and move the application=2E
The second issue I have with this method occurs when I take my=
executable and put it on another PC ( my PC is XP Pro, the other=
PC is XP Home=2E=2E Both SP2 )=2E The problem is similar, but a=
little different=2E When the 2nd PC's color depth is at 32bit,=
the transparency does not work=2E The green/lime ( that's the=
transparent color I'm using ) background shows=2E Needless to say=
this is not acceptable=2E When I change the color depth to less=
than 32bit ( 24bit this time ), the transparency actually works,=
but I come across the same issue of clicks on the transparent=
areas just passing through=2E
2) With this method I have not tried it on a 2nd PC yet ( I don't=
have it available where I am atm )=2E Its basically the same=
"issue" as mentioned above with color depth less than 32bit,=
except it does it with a color depth of 32bit and 16bit=2E Clicks=
on the transparent areas just pass right through=2E I'm tempted=
to just go with this method and possibly make one area on the=
form that is meant to be used to drag it around ( similar to the=
idea of the box that appears to move tables in MS Word ), but=
I'm hoping there's a solution I'm unaware of before I do that=2E
Anyways, all of this brings up some interesting questions=2E
-What does color depth have to do with transparency handling?
-Does the version of XP ( Home or Pro ) handle transparency=
differently?
Probably some more questions also=2E
Not sure if it matters, but I'm doing all of this in C#=2E
So any ideas to get pass any of these issues?
Thanks in advance=2E

Odd closing problem
I have a base form with a Cancel button (btnCancel) and a simple msgbox
routine. I would like to have a routine closing check to prevent loss of
data.
Dim i As Integer
i = MsgBox("Exit?", MsgBoxStyle.YesNo + MsgBoxStyle.Question)
If i = MsgBoxResult.Yes Then
Me.DialogResult = DialogResult.Abort
Me.Dispose()
End If
I have another form that inherits from the base form. In both parent and
decendent the Cancel button property of the form is set to (None).
The problem is this. Even given the above, even given that I've traced the
code and can see that the Me.dispose call is NOT being made when I click No,
the form still closes. Any suggestions as to what I might be overlooking? Tag: Custom datagrid Tag: 78900
Formatting txtPhone
I have a txtPhone that I need to format like 555-555-5555 and when a user
inputs numbers it should only take numbers. Tag: Custom datagrid Tag: 78899
strange problem with binding collection object to listbox control
I have a business object with two public properties - "OrganizationID" and
"OrganizationName". Pretty typical. We will call it Organization.
And I have a collection object which is an arraylist that stores a
collection of the business object described above. Let's call it
Organizations
I have a lstbox control. So I bind it Organizations to the listbox control.
lstSelectedOrgs.DataSource = null;
lstSelectedOrgs.ValueMember = "OrganizationID";
lstSelectedOrgs.DisplayMember = "OrganizationName";
lstSelectedOrgs.DataSource = Organizations;
I initially populate the control. Then I have a way to remove an item. And
then I bind it again.
At some point, all of a sudden, what shows up in the list box looks like
this.
MyNameSpace.Organization Tag: Custom datagrid Tag: 78895
how do I set the version information?
How do I set the version of my app? I can do this in the setup app, but it
does not coincide with the actual application.

Beta Readers Wanted - Whidbey C# - (O'Reilly Author)
This is a one time request for beta-readers for a new book I'm working on.
*************
I'm writing a new book on Visual C# 2.0 - target audience is C# 1.x
programmers looking to move up to 2.0 (code-name Whidbey).
The ideal candidates have been programming in Visual C# 1.x for a while, are
familiar with and comfortable with all the language fundamentals, delegates,
creating windows and web applications and so forth and are ready to learn
what is new in Visual Studio and C# 2.0, as well as highlights of what is
new in creating Windows and Web Applications.
I will post the chapters after I've written them but before they've been
edited or tech-reviewed. Your job will be to provide guidance and advice as
to how helpful the chapter is, what is missing, what could be clearer, etc.
You can expect to read (and respond to) about 40-50 pages per week through
Thanksgiving; starting next week. Ideally, you'll have the Visual Studio
2.0 Beta installed on a computer and will be able to try the exercises,
though this is not strictly required.
There is no financial compensation (though active participants will receive
a copy of the book when it is published, and an acknowledgement in the book
itself). You will need to sign a Non-disclosure agreement and you'll need to
join a forum on Delphi (membership is free).
If you are interested, please send me email (jliberty@LibertyAssociates.com)
with your name, email, C# experience, etc.
Thank you.

Logic Help
I need some help with user names and passwords (five users and one password
for each user). I have two txtboxes (txtName, txtPassword). If a user
clicks enter and both are empty then a message is displayed, "enter user
name." If just the name is entered the message "enter password." If wrong
name and right password then message "re-enter name." If right name and
wrong password message "valid name, wrong password." I cant figure this out,
can someone help me please? The names are tied to a passwords, for example a
user might have 123 for a name and a password of 456 Tag: Custom datagrid Tag: 78879
