Is there a way to generate a sine wave sound with a particular frequency?

use int.TryParse to turn your string into a number, and ToString to turn the result back into a string.

Does google not work where you are ? I gave you all the keywords you needed to find what you wanted.
dim i as int
if int.tryparse(textbox1.text, i out) then
i += 27
textbox2.text = i.tostring()
end if

This is my select statement
Dim mySelectQuery As String = "Select id,ClosedDate,Status,RecvdDate,SUrgent,EValue,GroupName,owner,CallDesc From vwHeat where recvddate >='" & startDate & "' and GroupName ='" & ListBox1.SelectedItem & "'"
In my database,some data in CallDesc in not in the same line eg.
My name is Rigard.
My surname is Mossi.
I write all the above data in a .cvs file.
I want this to appear as :
My name is Rigard. My surname is Mossi. in one line.
But when it get to my .csv file, it writes "My name is Rigard" in one line and "My surname is Mossi in the nest line"
How can I make this to be in one line in my .csv file?

By removing the Environment.Newline that's obviously contained in the string in your database.

Neither do we. What do you mean by "it dont do well"? What is it supposed to do and what is it doing that's wrong?

Hello,
I have 2 applications. In application 1 have a developed a simple setup wizard where the user has to enter some details. After they click next to continue and enter some more details. After they have done that, they will click finish. And Application 1 will call the setup of application 2 to install application 2
Application 2 will execute this line to install application 2
returnType = Shell("C:\Application2\setup.exe", AppWinStyle.NormalFocus, True)
The problem I have is that I will have 2 deployments, with the same name (setup). I wonder if it would be possible to merge these together, to make 1 setup.
I hope you can understand,
Many thanks in advance,
Steve

No, you can't combine 2 .EXE's into one.

What do you mean by this? You'll have to files with the same name is what? An .MSI installation you're making?

Hi guys,
I'm using DataTable, DataRow, and DataColumn on my DataGrid, and i wonder how can i programmatically set the width of a certain column on my grid.
Any code on workin on these three?(Data/Table,Row,Column) to set the width of a certain column?
Thanks in advance...

A datatable is a construct that contains data, NOT formatting information. You set the widths on your DataGrid itself.
Are you using it in ASP.NET, or in Winforms ?

As far as I can see, you've posted way too much code, and no question ?

I am extracting data from SQL Server to .csv file using VB .net. Some data in the database are separated by enter eg. They used an application to enter the data so when they entered in a list box the pressed enter to go in to a new line.
So, when I extract the data to .csv file, the data after enter they appear in a new cell and not in the same cell as the rest.
How can I remove the ENTER space using vb .net?
|

Either the code that produces the CSV file is incorrect, or the code using the file is. If the file is created and read correctly, a newline is perfectly valid inside the data of a field.
A field value should be quoted when it contains a newline. Example CSV data:
Id; Info; Time
1; Hello there; 2006-09-26 18:36:20
2; "This
is
a
perfectly
valid
CSV
file"; 2006-09-28 09:51:12
Note that the values in a 'comma separated value' file often is not separated by commas at all...
---
b { font-weight: normal; }
|
|
|
|
|
Look into the String.Trim[^] method to remove any whitespace characters from the beginning and end of a string before you write the data out to the CSV file.

How do i change the size of all the controls in the VB.Net 7.0 application
I need your help.
|
|
|
|
|
Do you mean at design time or run time ? I'll assume run time. If you set the anchor property on your controls, they will resize with your form. Otherwise, you can set the X, Y, Width and Height properties on the controls manually, if you need to ( you usually don't ).

How to add buttons in GIF format from net to application
I need your help.
|
|
|
|
|
Do you mean animated GIFs ? To do that, you need to download or write code that animates GIFs, there is an article on this site, but in C#, I think.
To load a standard GIF, Bitmap.FromFile will work fine.
