Thank you both .
It the 'indexof' function also not working .... it gives a true result may one time in 20 (when I know it is a true hit).
I think there may be a bug in vb.net. It doesn't matter what I do, it comes up with -1 all the time.
Did you try the code portion i added in my thread?
I tested it and it works fine...
obviously we can see the word AND is in the string JACK AND JILL.....
It makes me wonder what the ACTUAL strings are that you are comparing.
Maybe you could add them in a thread?
Its highly unlikely that the IndexOf method/function isnot working!
Its quite possible though that your installation of the development environment may have a corrupted file and possibly the next step would be to uninstall and re-install it again.
Still though, maybe you could save some time by adding your strings which your using in the comparision or even to upload the ACTUAL code block which is causing the offence?
Also, if your searching for a single character without specifying the number of consecutive characters to search, then the character must be in UNICODE, maybe that is of relavance?
Finally IndexOf is Zero based, so the FIRST character is position 0 then increases upwards, meaning it does not start with 1 but with zero.
Looking at the string "JACK AND JILL" and searching for a match of "AND" the code block I gave you states a match is found at charcter position 5, which taking it from a zero based index is ACTUALLY chracter 6 when starting from 1...
So maybe as a last resort you could subtract one from your start point (or start at zero anyway) and look for a match you KNOW exists in your string.
I have created a dll named myInterface.DLL that interfaces between my application and a 3rd party application. To do this I Added a reference to their Interop.3rdParty.dll and added an “Imports 3rdParty”. Everything works great. They released version 2 of the 3rd party app and added renamed their interops and name spaces. So What I am forced to do is create a new dll, myInterface_V2.DLL. This DLL is an exact copy of the myInterface.DLL with the exception of the what dll’s are referenced and the Imports directive changed to “Import CompanyName.3rdParty “ . Inside my DLL’s I have 3 forms and 2 Classes and as I stated above the only the only difference between my 2 dll’s is the “Imports” statement. So now my calling application checks to see what version of the 3rd party app the user has and calls the appropriate form in the appropriate DLL. So my question Without duplication the 3 forms and 2 classes is there a way to dynamically change the “Imports” statement, or can anyone suggest a way of doing this where I do not have so much duplicate code. I am hating the fact that every time I update the dll I have to duplicate it somewhere else. This is a vb.net dll and I am using VS2010 and a Windows 7 box.
I made 2 scripts under, the first for search all folders and subfolders (named "prive") in my R: Drive and the second for search security groups(begin by FR_DEPT ou LTGFR) on a folder.
I want to concatenate scripts for each "prive" folder, it could search if groups are affected.
Can you help me please?
Thanks in advance

i have created an application in vb.net to send email , with system.net.mail. But now i want to make possible for users to select multiple attachment , to remove one or some attachment and after to send with "send" button.
Can someone give me an idea just for begin , how can i do to manage multiple attachment before send process , (add or remove attachment ...). is there any control that i can use to keep attachment just like in a true email program.
Thank you !
p.s i'm using devexpress in my application , so if there is a control that can help me ?
Its as it says you can't directly run a class library project.
You need to create a WinForms / WPF or ASP.NET project and reference your class library and implement what is required to run the code.

A class library project creates a static or dynamic library, and contains classes and their associated methods and properties. In order to use these classes you need to create an executable which creates instances of the classes and calls their methods as appropriate. For a simple test of the classes you can just include them into your project.
One of these days I'm going to think of a really clever signature.
I am using visual studio 2008 vb.net and msexcel 2010. am continuously pass data to ms excel it will generate a xlLine Chart. It is working fine in my PC but not working in clinet pc. they also using excel 2010.

I've been at this on/off for about a week now. I put it to the side & move onto other things and now I'm back to it.
I have a datagridview (dgvScheduleInfo). In its properties I have the "ReadOnly" set to true. I have 6 columns (0-5). The last column ("Notes") I want to make editable if someone clicks on a "Edit Notes" button. Sounds simple enough.
I've used the following code to no avail:
dgvScheduleInfo.Columns(5).ReadOnly = False
dgvScheduleInfo.Columns("Notes").ReadOnly = False
The code above errors out with a "Object reference not set to an instance of an object." even though when I step through the code it shows "Notes" as the name.
I've tried hard-coding a value for testing purposes:
Hello: I'm working on a large database project that I currently have in VBA/Access 2007 and intend to put into VB.Net/Access 2007 as I think it might be a better idea but I'm not sure. This program is for a large law case where I will be required to deploy it by sending it out on disks to various other firms across the country. I'm a bit rusty with this so I want to know the best way to handle the solution. If all these other firms don't have Access, what other type of database should I use? What is the best practice for deployment?
Your users do not need to have Access installed; you'll need the JET/MDAC libraries, that's what VB needs to read/write Access-databases. If you need some of the functionality from Access, you could distribute the Access Runtime[^].
I'd recommend against using Access, unless it's a single-user database. Sql Server (Express) would be a more reliable way.
