Hi everybody, I'm having some problems with this function. The case is the following:
I have a picture box control and I put a shape control inside the picturebox, when a I click inside the shape it fills with the color I choosed. Everything is ok until now. The problem is that when I minimize then form and then I maximize it again, the shape is not filled.
Somebody has an idea to solve this problem? What am I doing wrong?
Thanks in advance.
P.D. Excuse my poor english.

Your not putting all of your painting code in the Paint event of the form or picturebox. Really, you don't even need the picturebox control. Personally, I think MS should remove it from the toolbox.
There are a variety of ways of doing this, but I'll just describe one. If you're not painting an image using the entire client area of a form, I'd drop a Panel control on the form and then put all of my code in the Panel controls Paint event. You'll get a Graphics object you use from the event args in the Paint event. Use that to execute all of your painting methods. You don't even need the Win32 API to do this.

Google?
Check out Microsoft .Net compact framework, make sure the platform you are developing for supports the compact framework before you start doing work for nothing.

I need to send values to the textbox in Report section of Crystal Reports in VB.Net. How do I do this dynamically (thru code) ? Someone please Help. Thank you in advance.

How are you sending data to your Crystal Report ?
One method is to build a dataset, then bind it to the report. The report is designed off this dataset schema. Look for examples on binding datasets to Crystal Reports.

Hi, Besides binding to dataset i am sending individual data (say report starting date) to the text box placed in report header, to which i want to send date value. Pls help. Thank you in advance.

Hello,
I had a small program that i was HOPING would work!!!
This program worked fine on a memory stick as it was writting data backward and forwards, in.txt files. I wanted to give a copy or it to my mate so i put it onto CD-RW however that then went tits up, it couldn't find the .txt files when they were clearly on the disc.
One of my mates said that it might be more secure to use a web server, this program asks the user for a licence key and if its correct then they are allowed on the program, the CD-RW was supposed to take the computer seria number (just like the memory stick did)
So i guess i have got to consider the option of a web sever.
Now where do i start?
I have no idea how to link a web server to vb.net. I know that one of my cousins has go a home server (will that work) it might save me some money 
Or can someone magically solve the vb.net problem and make it so the CD-RW works
Many thanks
Dan

I can't see it ever working from a CD-RW myself. If you create an installer to install it onto your friends PC it would work.
The core problem is that you cannot open a file on a CD for writing. I guess you are opening the files for read/write.
When writing to a CD you always have to burn the files back to disk, even when it is a rewritable disk.
You don't need a web server to deploy a simple .Net application. In fact you will only need on if you are developing a web application.
If you have knowledge, let others light their candles at it.

aaaah ok thanks for that!!!
|
|

I am thinking about scrapping the txt file and basically having a setup wizard, once this is then complete i want the cd-rw to basically delete the setup wizard on the disc, can this be done?
|
|
|
|
|
No, it can't. You cannot overwrite a CD while it's in use (your installer is still running!)
|

I can't really say a lot without knowing more about the program. If you can run it from a memory stick, then you should be able to run it from a CD-RW. It sounds like you have hardcoded paths to the files, and when you put the program on the CD, that is a different address.
To answer better we need to know more about the code. For example, show the code where you are opening and working with the .txt files.
If you are making changes and writing back to the files, then you can't do that on a CD without a bit of work i would imagine.

i hadn't hard coded the code for the txt files, that is why i don't get it??
I was thinking a bout using a web server as i am hoping to sell this application later on when all the bugs are fixed but dont really know alot about using a web server etc
thanks for the reply!

But did you build a fully qualified path to the file?? If you just specified the filename for the text file and not the full path to the file, you can run into issue like you've described.

Hello Experts,
I don't know what is com Port. And How to Connect PC to Hardware using Com Port.
IS RCID is related with us.
Actually i want to get Help for com port.
I think i submit the question in right side.
Thanks
If you can think then I Can.

How can you possibly write code to handle a COM port when you don't even know what it is or what you're doing with it??
|
|
|
|
|
Com Port is usually a 9 pin D port at the back of your pc, as so known as a Serial Port, using the RS232C standard. I is usually used to comunticate with other hardware devices such as weighing scales, clocks and back in the day, mice and modems. They are largely being superceded with USB devices.
VB.NET includes a SerialPort component.

Thank you Sir,
What is the Relation of RFID to Com Port.
If you can think then I Can.
|
|
|
|
|
You need to explain what you mean by RFID. Radio Frequency Identification?
It's just another serial device. How you communicate with the device, how to format the data you send and how the data your receive back should all be in the manufacturers product manual.

Hello All,
I have called PrintDocument.Print() method to print given document.
How to check given print is success or not.
Regards,
Sri

Normally, you don't. Normally, once your app prints it, your app shouldn't care at all about the job. The job may get hung up in the queue for various reasons, including being about 20th in line to print, none of which are the responsibility of your app to report. It may be an hour before the job actually makes it to paper, even if theres nothing wrong. Those conditions are left up to the printing system to report to the user, not your app. Normally...
What is your app doing that you feel the need to know if the doc printed or not?

Thanks Dave,
My application is printing checks. Before printing check number is saved to database. If print fails at any reason (Paper Jam,Paper Out,Not connected...etc) i nedd to update database with default check number "000000". Thats why i need print staus of check.
Dave, Can you please give me idea to get the status.Please
Thanks,
Sri

You'd have to get the information using the classes in the System.Printing[^] namespace. This is oknly available in .NET 3.0 and above.
If you're using .NET 2.0 and below, you'd either have to use WMI and the System.Management namespace to do something like this, or implement printing directly to the printer without going through the print spooler. You can find an example of that here[^].
