Yep theres nothing stopping them from doing that however i would say 90% of people would first run the program before copying it.
Does any body not know how to take a file of a cd-rw?!?! No offensive but i joined this site because i tought it gave help? I know there are goining to be porblems with the program but they can worked on!!! All i wanted to knwo was how to delete a file from a CD-RW in vb.net

Try to delete the file with the windows explorer or a command line! You will see, this ist NOT possible in this way. The only way is to create an ISO image and burn it to CD-RW. But this are basics in computer usage, I thought a developer should know some of the basics.

I already told you it cannot be done. Your installer is running off the CD, thereby LOCKING THE DISK FROM CHANGES. You cannot delete a file off the CD because you have to reburn the CD in order to do that, but, since there are open files on the CD (i.e.: your installer), the CD is blocked from being written to.

I have a licensing server setup. My apps gather information from various points in the system, combine it all into a "signature", and send it to my server. My server gives the OK if it's safe to run or not. My apps "phone home" every time they run, so you must have internet access to launch them.
No, you're not getting the details on how I do this because, obviously, I don't want those details out in the world.

Hi everyone,
I have created a setup project in VS 2005 for my application which is on VB.NET with SQL Server 2005 database. I have created the setup project with merge modules of crystal report ( as my application also has crystal reporting feature).
Now I want to deploy this on another PC, but that PC doesnot have SQL Server installed on it.
So do I need to install SQL server on my client PC for this, or any merge modules available for SQL server which can be added while creating the setup project?
Please suggest me how to go ahead with this. As time is very short, I need some quick solution, It will be highly appreciated.
Thanks
R.S.

Yes, or the user has to provide an SQL Server instance somewhere for your database to go.

Not that I know of. The SQL Server 2005 installation is entirely seperate and would have to run outside of your apps installer. Are you using the full SQL Server installation of can you use SQL Server 2005 Express instead?

I am using SQL Server 2005 Express.
Please suggest me what to do? Shall I go ahead with separate installation of SQL Server 2005 Express?
|
|
|
|
|
SQL 2005 Express has to be installed seperately. There is no merge module for it.
|
|
|
|

SQL Server Express should be installed separately. There is no merge module.

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.

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!
