Optimized Code For A Class Wrote?
Apr 5, 2008Whenever I decide to make a utility in VB.NET, I always end up writing a class like this one. I'm using it in an Explorer-like listview, and while I know it works, I have no idea (or experience) with coding for minimal overhead, speed, and precision. So I would like to know what I can do to optimize it.

.net - VB6 Code Upgrade?
Apr 20, 2012Possible Duplicate: Best Strategy for moving from VB6 to .NET Conversion tool comparisons for visual basic 6.0 Is there a good tool anyone can recommend to convert a commercial VB6 application into a VB.NET application. I have discovered some free ones and some commercial one's, but can't find any reviews and opinions of developers who have tried and failed or tried and succeeded.
What are the complexities involved? I know that .NET uses managed code and multi threaded apartments etc whereas VB6 is based on COM.

IDE :: Setup Project Upgrade Code?
Oct 22, 2009I have an application which has been deployed in a setup programme, but have lost the original project setup code.The new versions setup project has a different 'Upgrade code' GUI in the setup project and therefore when you try and upgrade the product it throws an error saying that a later version of the product is installed!
Is there any way for me to retrieve the Upgrade Code from an installed version of the program so that I can amend the new installer to match the old program.The program has to be installed to 350+ desktops via active directory, so no answers with silly shortcuts that only work for a single PC please people.

Loop - Sub - Wrote Only To Temporarily Fill The Database In During Run Time
May 1, 2009I have a sub that i wrote only to temporarily fill the database in during run time to be able to test a few other functions that i wrote as well ... weird thing is by the way i wrote it it should only look 100 times... but by the unique ID in the database and the information it pulls back into my list box it loops 700 times before actually stopping the loop ...
Public Sub Fill_LeftOvers()
Dim x As Integer = 0
conn.Open()
[CODE]...
Now i used step debugging and sure enough it only loops 100 times during stepping but in the database it looped like crazy ... i have also tried while x < 100 instead of the do loop but it did the same thing ... i know this may be considered a double post i mistakenly posted originally in the PHP forums earlier today ...

How Is Upgrade To SQL
Feb 13, 2009I have written an address book and for its database, I used Access to create a .mdb database and store my data programmatically into this .mdb file.However, the problem is that when reading and saving data to this kind of database I have to use Jet 4.0 which is NOT available on 64-bit systems and I have to compile my application as 32-bit in order to run on all systems.I just want to know how is upgrade to SQL?I never used SQL, can I create a stand-alone database file using SQL like Access and create tables/fields so I can modify it programmatically?I also need the database file to be independent and don't need any special requirements to run on target systems, like the .mdb file I've created in Access!
View 1 RepliesNullReferenceException In .NET After Upgrade To 4.0?
Jul 25, 2011I have a VB.NET solution that I just upgraded. It was originally in .NET 1.1, I upgraded to .NET 2.0 and verified that it would build and run correctly. Then I upgraded from 2.0 to 4.0. It is still building with no errors, but when I try to run I am getting a NullReferenceException in Global.asax.vb. The really weird thing is, the line that is throwing the exception is this:
Dim dt As System.Data.DataTable I am not trying to use the variable, just declare it. Further down a Function is called that returns a DataTable and sets the variable, but I don't even get to that line. It is throwing the NullReferenceException on the Dim line. Has anyone run across this before? Is this some issue with upgrading?
[Code]...
I did a Rebuild Solution before posting. This is a web application and the only files I see in the bin folder are the dll files I am referencing. I'm not sure what else I should clean up.

View 2 Replies.net - Upgrade Software From VisualBasic 5 To 8?
Jan 23, 2012I've given a VisualBasic Software, written in VB5. Now the whole thing should run under Windows 7, so it needs to be converted to VB8 or VB9. It seems that most of the API of VB changed a lot in these years, so for me it seems quite impossible to run just a few code upgrades and everything is fine...
The biggest Problem are Forms. There are a lot of Forms in this Software, which are declared inside .frm files and begin always like this:

It seems for me that this Stuff was generated with an UI-Layouter, so none self written code is in there.Is it possible to run this code in VB8/9 or even rewrite it that VB8/9 understands it? I'm currently very pesimistic and think that the whole software needs to rewritten...

If anyone has any incite to correct this issue then that would be great as i have not found a way around these errors!
Control The Upgrade Through A Program?
Dec 15, 2010I've written a VB.Net program and it's deployed all across the U.S. When I make changes or bug fixes and want to get a new version out to my clients, I'm wondering if there is an automated way of upgrading the clients. I cannot use Click-Once deployment, I have over 7,000 users and want to control the upgrade through a program. Is there a tool in the toolbox for automating this process?
In VB6, I used the INet control, is there an equivelent to this in .Net?
Mdb Error Due To Office Upgrade?
Sep 28, 2011I have been supporting vb.net application which worked fine with office 2003 but when one of my client upgraded to the office 2007.then we got a error like this after a bit of research ,i found that
"One possibility is that the file is corrupt (Access databases have a tendency to do that -- see
Article #2190 for a way to compact / repair the database through code). A more common reason is that you are trying to connect to an Access 97 database with Access 2000 or better drivers, or vice-versa. Make sure the server has the most recent MDAC (MDAC Download Page) and the most recent JET drivers (see Article #2342). Also, try upgrading your database to a more recent format (Access 2000 or better)."
may be my case is similar.the applicattion is working fine with the other users ,only the user who upgraded to office has got the problem.
Resizing Form After Upgrade?
Mar 4, 2011I have a windows forms program that I upgraded from VB 2005 to VB2010. When the program was on VB 2005 the form would resize to any monitor resolution. But since I upgraded the program to VB 2010 some of my controls are off the screen when I run my program on a 1024 x 768 screen resolution. Why is it doing that?

Oct 30, 2009I have a big application which is really working succesfully written in VB.Net version 2005 I am wanting to upgrade this to VS2008/2010 early next year. All versions used would be the fully paid for versions
I am totally clueless about what this upgrade would entail. I cannot afford to re-write the entire application as it is critical to our business.Can I take my code across without too much hassle? And then slowly "re-write" the code to take full use of the new features. Would i need to attend some sort of "new features" course? Or is the accompanying documentation good enough to get by.
