how to integrate an application to already developed application
i mean to say,if i thought of updating an extra module for an application developed by other person.
i just have database and setup file
how to Update
Plz help................

That would depend entirely on the other application, if it exposes any interfaces or services, what API's you would have to use, database concerns, ... EVERYTHING depends on the capabilities exposed by the other app. Without knowing anything about it, it's impossible for us to tell you anything useful.

Thank U Fly for ur reply s
actually i want to copy an image and resize it to specified height and width

Google 'vb resize image'[^].
Once you have opened the image you can resize it, then you can save it in the new position.

Uhh... That message is comming from Visual Studio! Your application is shutting down the system, causing Visual Studio to give you this prompt because it's being told to close!
You didn't really trry to run your app outside of the debugger yet, have you?? You won't get that message if you try it.

Go to where you saved your project, then go to bin\debug folder and launch your application as you would normally, this will work. Visual Studio shows you this message because you are "Debugging" at the time your program tries to shut down your computer. So, stop debugging for a sec, and check out the exe file that Visual Studio has created for you. It shoult be somehwere like: \....\Visual Studio\Projects\YOUR-PROJECTNAME\bin\debug\YOURPROJECT.exe
hope this helps

how to set connection string after deploying the project
|
|
|
|
|
Store it in something like the app.config file?? Then you can modify it to what the user needs and load it when you need to using the Configuration and ConfigurationManager classes.

It's really just simple string manipulation. You have an options form in the setup where the user can enter the name of the server and instance and possibly the database name, then you use that information to build a new connection string, possibly test it, then save it to the app.config file using normal XML methods.

hello
i had developed windows application in vb.net and sqlserver.
used sqlserver provider
created an setup file
my doubt is,Is it compulsary to install sqlserver on the client machine to run the project and if yes how to get the database Name and sql server name
for connectionstring
Please Help me
|
|
|
|

No, you don't have to run SQL on the client machine, you can run it anywhere the client machine can get access to, like a centrally located SQL server for example.
But you developed an app that used SQL so you should be accounting for needing it when you deploy the application.
Your project should store the connection string in the apps xml config file so you can set it to what ever you want once the app is deployed, not hard coding the values in the app (sounds like what you did).

Hi friends,
I've a textbox and a button in my WinForm. Now, I want that, whatever the user enters in the textbox and clicks on the button, the entered text should be copied to a precreated text file "C:\test.txt". Note, that I am using Visual C# for this purpose. I searched google and MSDN, but my search ended up in futile. Please help me out with the appropriate code.
Hope to hear from you guys soon,

Well I can give you simple idea. I provide you source code you need to modify it. I am having some problem with my computer else I will do that proper code for you . just post you some my old exercise .
just put this function on the button click I mean where you want it will save . If you want to save automaticaly you just modify .
private void savingtext()
{
SaveFileDialog savetx = new SaveFileDialog();
savetx.DefaultExt = "rtf";
savetx.Filter = "Texto enrriquecido (*.rtf)|*.rtf";
savetx.FileName = "Log.rtf";
if (savetx.ShowDialog() == Windows.Forms.DialogResult.OK) {
textbox1.text.SaveFile(savetx.FileName);
}
}
Wisht it will help you

I'm sorry, but I just cannot believe how many people have asked the same question on so many different forums. There ARE MANY SOLUTIONS to your problem at hand that can be obtained from a Google search. And by many, I mean thousands of solutions.
Here is the code. I'm only doing this because I'm in a good mood today. Any other time, you'd be ^h%t out of luck.
Double-click on your button that you've added to the form and inside the event handler type:
File.AppendAllText(@"C:\Test.txt", textBox1.Text);
..That is ofcourse, assuming your TextBox control's design name is still textBox1.
Now, for this to work you need to include a 'using directive' in the top of your file like so:
using System.IO;
Hope this helps.
Jason.

When i use below code, it returns true and then i changed the condition to check m=1 then its returns false. I am little confused about booleans so please let me know the internal implementation about boolean.
Dim m As Boolean = 1
If m = -1 Then
MsgBox("true")
Else
MsgBox("false")
End If
I know that using "True" or "False" is best practise but for better understanding i need this
Thanks in advance
Regards
Azeem

A boolean can be either true or false. Best practice is not to use 1, -1,0 etc but use true and false as the actual values can be operating system dependant.

Once you set the Boolean = to 1 are you sure that it is staying at the value of 1 and not being altered to equal how VB internally stores a true or false value?
Why do you want to create a Boolean then assign it a number and compare it to a number?
|

Trying to locate a link that shows you why this happens, but what you are seeing is type conversion related. VB.NET stores false as a 0 and any other value as true, but that defaults to being stored as = -1.
So, when you assign the Boolean = 1 it gets converted internally to -1 because it is not a false value (0).
Try doing a few debug.prints and setting the Boolean to a few values and see what happens.
It looks to me like you do not have option strict turned on. If not, you should because it forces your code to be far more explicit and not allow type coercion (dynamic type conversion) like this.

0 = nothing = false, the rest is always true
A more proper boolean;
enum MyBool = {
true,
false,
EFileNotFound}
