i'm new to the VB programing world, actually to programming world in general, so before i start i have a question. I've heard that to run programs created in VB you need to have NET Framework on your comp, is this true?Cause i found somewhere on the web that you have a exe in your Debugging folder, and i tried running it on my friends comp which is without framework and it worked. Don't know if this was some error or something, and if there will be problems if i run them like this, so i wanted to ask professionals,
I am trying to make an application using vb2008, and I'm facing a problem. I have a command button, and I want it to generate a new groupbox each time it's clicked. So here's the problem: when the user clicks the button, the previous groupbox disappears, which is sth I don't want to happen. Also, I wonder how I can use each of the controls included in the groupbox, while I can't name them or something...

I am trying to create a program which loads a Excel file (03) with various worksheets, and the user can update them.I think it should use the Tab system on vb (08 express) and have each worksheet on each tab.On the tab, it should list the first 8 cells.
i know this may soiund a bit of a n00bish question or 1 that pops out every now and then, but i am havin trouble trying to round off nubers.basically i ahev this label where a value i s inputted by the system after it goes thruogh user inputting so:1)user inputs somehting (* by somethingh)2) user input (* by something )etc etc.val(label1.text) = the additon of all those user inputs---to make life easier lets ust say user input1 = user input 2 k sometimes the val of label1 becomes a decimal point like 3453453.666777 etc when this happens i just want to round up to 2 decimal places i have looked on msdn for help which gave me:
Im trying to build an activeX control to be used in excel using VB08 Xpress addition. I have found instructions to create a Class Library Project, then add a user control. Under Build there is only one option, Build "Project Name", no options, no nothing. The build creates a .dll file not an ocx (which I was expecting?)
The problem is that when I compile the control I get a .dll file that I cant register as a activeX control, therefore I cant use it in excel. Ive tried to create stupidly simple activeX controls, ie one label that says "Hello World", still no luck. When I try and register the .dll file, it doest work, therefore no dice with excel.
The strange thing is that within VB08 Xpress I can use the control in any Windows Form Application I create.
I have a datagridview that I'm populating from a SProc. The data coms back fine and is presenting in the DGV without any trouble, but I don't like the order the data is being returned in.A long solution might be to modify the SProc to return the data in a different order, but I prefer to handle this on the UI for simplicity. Also, I know the user can re-order but that presents a specific poblem in the way the columns are structured.Is there a way to programmatically change the order at runtime?Here's the ode I have on the UI. If you need to see the adapter class also, please let me know and I'll present it, too.

I just joined this forum as I've been looking for a nice and serious VB forum for a long time
I'm having troubles making a program to search a text file line by line for a specific string.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim objReader As New System.IO.StreamReader("C: est.txt")
[Code]...
as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.
now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost
for a "Readnextline" command or something like that?

I am trying to translate some VB codes to C++. And I am not quite sure what this line does.
IIf (n& 1=1, 0.0005, -0.0005)
I know what IIf(logic, true_value, false_value) does, and I guess the & operator is supposed to concat two strings. But I am not sure what the intention of using "n & 1 =1".

I am using Microsoft.Web.Administration to create NEW websites programatically. How do i change all ID's starting from zero? Currently i have about 100 websites and they are ordered like following:
1, 2, 4, 18, 200, 1234, 232324, 2455344 etc. etc. And i want them ordered like this: 1, 2, 3, 4, 5, 6, 7, ... etc. up to 100.This question doesn't have to refer IIS and the Administration class directly. I just need to change the id like you change the values into database or array/arraylist or generic list.
Means the value with 1234 should be 6 if six is not already taken or 18 should be 3 etc.
Dim myDelims As String() = New String() {"<beginning of record>"} Dim split1 As String() = temp_string.Split(myDelims, StringSplitOptions.None) For Each s As String In split1 If InStr(s, lot__no) Then
for some reason, the first s in split1 is giving a value of "". there's nothing in it.why is it starting ONE before the first element?
This is for vb.net I've been working to develop a system which involves computation.What I've been trying to develop in my program is, I have a textbox where user will enter a numeric value,there is a button and a label below and in the first place the label should be set to zero. Everytime you enter a numeric value in the textbox and click the button it should add the value in the label and should save the value in the label so even if you exit the program whatever the last value displayed in the label should remain the same when run the program again,I believe it requires a database to save the value.Basically its like with payment system which saves the total amount of all payments made.
This is how should it works,say for example,if you will enter 1,2,3 it should save the sum value which is 6 in the label even if you close the program and when you run it again and enter another value it should add to the current value which is 6.
In C, Pascal, and C++ it is possible to use the FormatMessage function to retrieve a "friendly" error message that corresponds to a COM HRESULT error code. This question contains sample code that demonstrates the C++ approach. Of course it would be possible to build a managed C++ assembly to perform this function for C# and VB.NET code, but I'm wondering: is there a way to translate COM error codes using the .NET system libraries?
I need to be able to write data to a binary file. No problem - I have a test app I've knocked up that reads and writes to them fine, however the format uses C0 and C1 control codes, and I have no idea how to write them properly. The SOH, ENQ, DLE, NUL type of thing. I'd post some but they are non-printing. I know what they mean and what they do but have no idea how to write them.Basically we are writing our own system that generates test data files for import by another program. My files that I write have the correct number of fields and correct value and formats but because I can't get the tags to write they data is imported incorrectly. I've spent days reading up on it but can't find what I'm looking for.Not dealt with binary data files in VB before so this is all new.
