You should draw everything in the Paint handler
The Paint event gets fired whenever:
- something changed in the environment, e.g. your form got covered then uncovered
by something else
- the form's size changed (maybe minimize/restore, maximize/restore, regular resize)
- your code calls Invalidate()
So when your internal data changes and a repaint is needed, call Invalidate(),
dont paint things yourself outside the Paint handler.

You're obviously using CreateGraphics. What led you to do that ? It's totally wrong, and so many people seem to be doing it, I don't understand why.

I'm having a fit over here--most likely because I'm new to ReportViewer. I'm sure this must be pretty simple, but I've been banging my head against it for a couple hours and I'm hoping you can help. Available futzing time is EXTREMELY short on this one.
I have a single-record-display report, with no Table/Matrix controls--just TextBoxes, lines, etc. I need to send multiple records to the report and be able to navigate through them using the report's ToolBar buttons--First, previous, next, last.
Each button click should move to a different record and update that record's information in the TextBoxes. When the report is printed, a single page for each record should be produced.
Currently the ToolBar shows only one record, even though the report's underlying DataTable contains many.
Surely this must be possible?
Thanks!

Why are you not using Table or Matrix controls? I've had this problem in the past and using a Table makes it go away :->
OT: I took the "U" word out of the subject line since it can upset people around here. I'd recommend modifying your subject line

Oops, I didn't realize that! OK, I fixed it, thanks.

Er, maybe I'm missing something? If I use a Table/Matrix control, the data will display in tabular format on a single page of the report.
Maybe I didn't describe it too well. I'll try again.
I have 5 customers in a table. Each customer has a name, company and an account balance. I need a 5-page report with each page exactly the same except for the name, company and balance fields.
Like a mail merge. In fact, EXACTLY like a mail merge.
Thanks

You could stretch out the height of the cells to force one customer per page.

The 'customer' example I gave is a pretty simplified example. In reality, the report layout is pretty complex--a lot of data fields mixed in with plain text snippets, lines and so on. There wouldn't be room for the stretch you describe, I don't think.
There's no way to do it in the report configuration?

I'm not 100% about that. as far as stretching at the bottom, just have a filler row in the table at the bottom before the footer. Sure would be nice if it had a page break thing in the toolbox like MS Access Reports has

I couldn't get that one to work like the list grouping. It must be the grouping that does the trick. In this case I used the table's primary key.
I'll have to fiddle with this one later on when I've got some more time.
(Time? You mean someday I may actually have TIME?)

Originally he had a certain word in his subject line that would have gotten him flamed, and he took it out

Hey all,
I am attempting to create a program that runs in the background, takes keypresses from the keyboard, changes the keypresses to different keys, and sends the new key to the program running in the foreground (for example: I press "A" and the program in the foreground gets "F"). I thought that DirectInput would be the best way to go about this. However, I cannot seem to initialize the program correctly. I want to use the below code to gain control of the keyboard:
Dim keyboard = New Microsoft.DirectX.DirectInput.Device(<SEE BELOW>)<br />
keyboard.Acquire()
However, "Microsoft.DirectX.DirectInput.Device" wants the guid of the keyboard passed to it as an argument, and I cannot find out how to get this. So, How can I find the guid of the keyboard? I have looked all over the internet for the way to do this, but all I can find is information about directx8 or code in C++.
Also, while I am asking, will this program prevent the actual keypresses from getting to the program in the foreground? Using the example from above, if this program can't hide the actual keypresses, then the program in the foreground would get "AF", instead of just "F". Thanks for taking the time to help me.
NOTE: I am using Visual Basic 2005 Express Edition.

You don't need DirectX or DirectInput for this. Just write a Global Keyboard Hook. Search the articles for "keybook hook", or Google for "VB.NET Global Keyboard Hook" and you'll find lots of resources.
|
|
|
|
|
You can find the keyboard's guid on here:
Microsoft.DirectX.DirectInput.SystemGuid.Keyboard
In other words, you should create your dxkeyboard object like the following example:
Protected mKeyboard As Microsoft.DirectX.DirectInput.Device = Nothing
mKeyboard = New Microsoft.DirectX.DirectInput.Device(Microsoft.DirectX.DirectInput.SystemGuid.Keyboard)
Sincerilly yours. Manusoftar®

I have developed a software in .Net framework 2.0.
When I install it and then try to uninstall it, it shows the following error message:
Could not open key:HKEY_Local_MAchine\Software\Microsoft\Protected Storage System Provider\*Local Machine*.Verify that you have sufficient access to that key,or contact your support personnel.
I am using my administrative account and it is showing the same error.
What to do?

Not sure and it doesn't sound good.

Hi, would you please explain the Encoding.UTF8.GetBytes("abc") part of the following line:
Dim b As Byte() = Encoding.UTF8.GetBytes("abc")
I've read about what UTF8 is but I'm not real sure on how to use it. Also I don't know whether "abc" is the name of a datafield or a function. Please elaborate, thank you in advance for your help.

The GetBytes method will return a byte array containing the UTF8 representation
of whatever string is given to it.
I trust "abc" is just a silly example here.
Read the documentation for more.

"abc" is a literal string, concisting of the three characters 'a', 'b' and 'c'.
Encoding.UTF8 is a static property in the Encoding class that returns an Encoding object for the utf-8 encoding.
The GetBytes method encodes a string into an array of bytes. Each character in the string is encoded into one or more bytes in the array.
The three characters in this specific string are each encoded into a single byte, so in this case the array will contain three bytes.
