I'm working on porting some classic VB6 code to C# and just stumbled across a usage of the PV function.I feels wrong including a reference to the Microsoft.VisualBasic Assembly. Is this something that is commonly done, or should I explore further options. The next idea that pops into my mind is exploring this PV function in Reflector.

I've been wondering about this for a while, but is there actually any free way to port VB.net apps to OS X and Linux? I've searched the web for this and couldn't find anything much.
View 5 RepliesI'm working on some legacy VB5/VB6 code and need to convert a ".bas" file to vb.net. i found several options
Compile the .bas file into a com dll and then reference and use it in my project. (For this I guess I would need vb5 or vb6 which I don't have at my disposal) Copy and paste the contents of the file in to a new module in vb.net and then try solving the errors one by one.The contents of the .bas file reference a particular dll. The .bas file has mostly declarations consts, types, sub's and functions.
What would be the most elegant way of redoing this in vb.net. Is it as simple as option 2.EDIT
I used VS2008 express and ran the code through the upgrade wizard it did the necessary conversion. and the .bas file was converted to .vb. I took that file and decided to rewrite other parts of the code, including some redoing of the converted .vb file. Other questions related to this one are here.
We are looking to port our existing classic ASP application to .NET, but we're unsure of what language to use for the new app. I personally would 'prefer' C#, as I'm more familiar and comfortable with that languages way of doing things, but, the original code is VBScript, so it would possibly be easier to port to VB.NET ... One possible situation I fear would be that, because the code is so similar between the two variants of VB, that we might end up getting stuck on something that is not similar between the two, even though it looks like it would work. A shift to a wholly different language might avoid that kind of situation. Does anyone have any practical examples of this kind of situation? Insights to illuminate the issue with? Do the potential benefits of a complete paradigm shift outweigh the gains from a high degree of 'copy-and-paste-ability' ?
View 9 RepliesI am porting a vb6 application to VB.net. One of the key forms has a large msflexgrid on it - about a 1000 columns and 50 rows. It has 2 header rows - the first header row has merged cells to form a main header and the second row has sub headings. There is no requirement for any data entry and it's unbound. The code does the work in deciding what to display (if anything) in each cell. It is solely used to display data in the form of a character and a coloured background and to display a tooltip text with more information when you mouse over it. Works beautifully in vb6. I'm trying to decide whether to:
a) use the vb6 msflexgrid in the .net version
b) use the datagridview - which at a first glance seems to have a problem merging the cells on the header row
c) build my own custom control to do the job
I've got a VB 6 application that I ported over to VS 2005. The application has a toolbar on it. When building it in VB 6, I created all the bitmaps for the toolbar. And they looked just fine.Now I have ported to VS 2005. The toolbar works just fine. But the images in the toolbar look "wrong". The best way to describe them is if you took each bitmap and squeezed it down to about 67% of it's size. So it is missing the detail it used to have. And the smalleer picture still takes up the same amount of space on the toolbar. It is just that each squeezed bitmap now looks like it has a thick, blank pictureframe around it.

I created an application for Windows XP, now it needs to run on Windows 7. I have had some issues to resolve, but rather small ones. I am now stumped on this one... Here is my code block

The code works perfectly for Windows XP, but the ftpRequest does not work in Windows 7 for renaming. That said, the code runs that entire sub becaues WriteToEventLog get's written, but seems to ignore the ftpRequest lines.
I need to update (well, rewrite really) a SMALL VB6 application which uses ADO to access a JET database, to a vb.net app in Visual Studio 2008. My research suggests that I should use LINQ, but it doesn't seem to be possible to connect to JET. If JET is now deprecated, what should I use? Or should I use ADO.NET without LINQ?
Please don't answer SQL Server! - this needs to be an app that end users can install easily in corporate or non-corporate environments, and must not require any ongoing technical maintenance. I started to install SQL Express, but stopped when it required at least 2 system updates, as that will be far too complex for this little app.
I make loads of programs in visual basic, but it happens that my friends that want to try some, have Windows XP or Vista, when I have Windows 7 on the computer where i create them.I tried to launch the application compiled on 7 on their PCs but it just doesn't work. Is there any way to port programs from Windows 7 to other version of Windows? Or just to find a way to make them run?
View 9 RepliesI've been asigned to a new project. I have to mantain an application wich was made in Visual Studio 2003 (VB.NET, Framework 1.1) and Crystal Reports wich came included with the IDE. The application is absolutely what we call "legacy code" :).Just to make the test, today I've tried to convert the application in Visual Studio 2010. The converter is offering me download SAP Crystal Reports, with no cost and no registration.The question is: Does anybody has experience with this components?. Is feasible to migrate an application as described to VS 2010?

this code was not done by me originally and there are some thigns here i dont quite understand i have altered it a bit from my coworkers code to suit my data and it works. but too slow. and when i have 4000+kb excel files it might freeze altogether. ( I have checked tho that when and after this transposer runs it will still be within the excel row limit, i had done calculations before and made a macro to automatically split excel files based on number of columns and rows to make sure this is so ). This code seems to start out fast then goes slower the longer it runs. at least this is what it seems liek to me.

I recently found this code (provided for third party use on another VB site), however,ll of my attempts to insert it into a class library have failed.I open a new class library and past the code in, and immediately get several errors pertaining to how certain objects can't be found. I find it it is crucial to use this code, unless someone can suggest to me another example of existing code that will do the same thing: make a restricted textbox who imputs can be restricted, that can handle pasting, shortcuts, text property setting, and script-entered text.

View 2 RepliesI realize this post is rather long, but I wanted to give all the information up front instead of people having to ask me for more information.At the end of the re-installation of Visual Studio 2008, there is this message:
"Microsoft SQL Publishing Wizard: [2] Error: Installation failed for component Microsoft SQL Publishing Wizard. MSI returned error code 1638" in the log file dd_error_vs_procore_90.txt.
I have searched on Google for this whole message and found some references to this error, but I have done what they said worked for them and it did not fix the problem for me.When I searched for just "MSI returned error code 1638", I got that it cannot install something because it is already installed:"Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel".In Add/Remove Programs I see these two programs:
Microsoft SQL Server Database Publishing Wizard 1.3
Microsoft SQL Server Database Publishing Wizard 1.4
Are these programs/versions what the error is refering to? Am I safe to remove them and depend on the similarly-named item which would be newly installed with Visual Studio 2008 - "Microsoft SQL Publishing Wizard"? I still use SQL Server 2000 and 2005 on my computer, as well as 2008. I had installed VS 2008 on my computer before without this problem and also have VS 2005 and 2010.
I'm using ASP.net 4.0 VB,I am using a session variable to add a user entered code into the url of each page. I can get the code to show up at the end of the page's URL that my textbox is on, but what do I add to every page to make sure that the session stays at the end of every URL that person visits during their session? This is the code from the page that the user enters their user code.

Session("IB") = IBTextBox.Text
Dim IB As String = Session("IB")

This is what I have in the page load of one of the other pages. What else do I add to make sure that variable is added to the URL of that page?

IB = Session("IB")

i am asking that can i use c# language to implement "actions" fired on "click side events" such as mouse over the reason for this stupid question is that i remember some syntax of registering functions for particular events of formview, which are call when the event occurs (yes there ispostback involved" is something like the above possible for client side events using c# or even vb.net
