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

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}

dear frenz,
i need to store the name of the parent node of the node selected in a treeview
i have used the following code:
parent = TreeView1.SelectedNode.Parent.Parent.Name.ToString()
but this gives the o/p as "TreeNode: 1203"
whereas i only want the o/p as "1203"
where 1203 is the parent node of the selected node.
treeview node level 0= 1203
treeview node level 2= selected node.
plz help asap.

You are getting but this gives the o/p as "TreeNode: 1203" because that is the name of the node.
try using parent = Treeview1.SelectedNode.Parent.Text;

Okay, here's a weird, nit-picky question:
I've added a new toy to the tools collection in my text editor. It changes contractions back to their "formal" form: "It's" to "It is" and so forth. So...
Is there a word for this process? "Expand" a contraction, maybe? "Replace" a Contraction? I'm trying to figure out the proper text for the menu item.
|
|
|
|

Well the antonym for contraction would be expansion - but I like the idea of altering con-traction and changing it to dis-traction - there's a certain logic there
