I am new to vb.net and need some help, I am trying to write a program for multiplication. I need to use the next method from an object of type random to produce two positive one-digit integers, that should display a question like "How much is 6 times 7?" and type the answer in a textbox.
I want to check the answer and display a message in a label of either "correct" then ask another math question, or "Try again" in the same label and try the same math question again.
I would appreciate any help with this, I know this may not seem like a very tough task, but being new to this makes it difficult for me.
thanks, John

Despite the fact that someone has done your homework for you, you should really look over the code, work out how it works, and in future, try to do your own work and post specific questions when you get stuck.

Hello,
I am developing database application using SQL Server. I need to use customized date format on client System. I don't want to chage the date format manually. Is there any way to chage the System Data format when I run my application via VB.NET
Thanx in Advance
|
|
|
|
|

I have done this but i want to change the system date as we change the system date through control panel--> Regional sttings---> date--> customize date.
its a manual way to change the system(PC) date but i want to change date formate through VB.NET code

Okay - All the extra information about SQL Server obviously threw me off course.
You will need to change some system registry settings. The following link tells you about settings that affect the display of the date: http://perso.wanadoo.fr/tmcd2/Country.htm#Date[^]
Be careful with this. Unless you are providing an alternative interface to the Windows Control Panel (and from what you've said you probably are not) you need to let the user know that your application will change the display date across the whole system. They will get very irritated if they find out your application is changing their date format against their wishes. If an application did this to me I would describe it as malware.

This is not recommended at all. One problem you'll run into is that normal users don't have to rights to change the system data format, even by poking into the regsitry. Another is if your code DOES manage to change the data format, your application must put it back when you're done. But what if your app crashes? Now the user must put the format back by hand.

If ur question is how to deploy a VB.NET application with sql Server then first you have to create a deployment project for your application. In deployemnt you have to add a file like DB.txt. this file must contain information about sql server name and databse name like "ServerName=ABC" and "DBName=BCD" and also userid and password if necessary. so you have to write the code to read this file and set these parameters in database connection. now you have to build the deployment prject . this 'll create setup.exe and some other files.
Now run this setup.exe on othere machine .this 'll install your application and now you have to install .NET framework and sql server on that machine.attach database to sql server
Now open the target folder of your application installed and open the file DB.txt and change the name of sql server if name is different to yours.
you can download .NET frmaework from microsoft.com (free) and also search the detail of topic "deployment project" from MSDN.
I think it'll help. if this help do tell me
