C# - Language Choices When Porting A Classic Asp App To .NET
Sep 7, 2010
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' ?

wondering if someone can help me some small issues I am having with building my first project.
1.I have comboboxes that allow users to enter their own choices in and then their choices are displayed into the gridview.
the problem I am having is this is allowing me to duplicate choices. for example:when I run debug to try my boxes, I can type in Johnathan into the combobox as many times as I want to and it adds is to the combobox list..so now I got 10 johnathans in my combo box.and then to make things worse, when I hit the button I made to send choices to display..it causes duplicated choices to show up in the display.What I figure is that it is easier for me to just prevent duplicates in combobox.
2.Lets say on one of 10 comboboxes I got...lets say someone skips the box and doesnt make a choice...my grid will then display the last choice made.. (man o man)for example:John chose in his boxes and is displayed on gridview: Combobox1 (john) Combo2 (5:00 PM) combo3 (waiting)now lets say I come up to the computer and in Combobox1(Dcurvez) Combo2( i skipped and didnt enter a choice) and Combobox3(In Progess)
The display will put Dcurvez....5:00 PM.....In Progress because I didnt make a choice in the time combobox..it put in the last choice (Johns) as 5:00 PM Can someone in very simple terms tell me how to fix this problem?? I am using visual studio 2008 and vb/vb.net as language this is not a webpage, btw. it is for in shop computer just.

In my winform app in VB.NET I want to use the localization option. But i have a few questions/problems. I'm using a menu strip to select an other language. But it seems that is doesn't change my menustip text to my selected language. It does change my labels, buttons, and textboxes but menu strips don't seem to change when I choose another language. Also is it possible to get those resx files such as MyForm.fr-FR.resx compiled so it isn't an external file outside my app? Or to get those files in an Language folder at the same location of my app, so i don't have all those fr-FR & nl-Nl folders in the same location as my program?

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'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.

I have 2 comboboxes, textbox and a cmdbutton. When the user makes a selection in one combobox I want it to filter the choices in the second combobox. Then when the user clicks the button it passes the values from the comboboxes to a stored procedure and populates a datagridview. I am using VB.net 2005 and sql server 2005.

I have two combo boxes, and four buttons. When the user clicks "Add" on the first combo box, it adds a new item to the combo box with "New" and then lets the user rename that item to something else. That "new" item has to have an array of "answers" that go along with that item in the list. What I'm having trouble figuring out is assigning "answers" to the second combobox for each item in the first combobox and changing the second combobox when selecting an item in the first combobox.
EXAMPLE:
Item 1 - Combobox1
- Item 1 - Combobox2
- Item 2 - Combobox2

I 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'm trying to display a random messagebox that displays a message associated with a character. the character image displays and the user clicks a button to guess the character if it is correct, one of three messages should randomly appear that is associated with that character (there are 4 characters, so there are 12 possible messages total. 3 for each character) but as it stands now, the picture box on the form displays the character name so the user doesn't have to guess which button to push. i need to remove the name from beneath the picture so only the buttons have the name and the user is forced to guess and i don't have the messages randomly popping up. only a messabebox that says correct i added a message box in the code but i can't figure out how to randomly get the messages associated with the characters to appear?

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 am currently programming in Visual Studio 2010 within VB.NET and am using DevExpress v10.2, specifically WinForms. In the DevExpress GridControl at runtime you can click on the right side of the column header and choose which values in the column you want to show. For example if your table contained:
Name1 Checked
Name2 Unchecked
Name3 Unchecked
Name4 Checked
Then if you click on the right side of the checkbox's header you can choose checked (or unchecked) and it would display only the data that is checked (or unchecked). In this case with checked you would have:
Name1 Checked
Name4 Checked
I was wondering if there was some way to override the names so instead of letting me choose checked or unchecked I could override it with 'owned' and 'rented' or 'active' and 'inactive' based on what the checkbox represents in that specific column.

how to save the users radio buttons choices to load into a file. I have a button which controls the If statements to determine the price of the configuration. I was wanting to save these choices that the user made. I thought I could do this by altering the If statements but I don't know if thats the right way. I've got 3 different groupboxes with 3 options in each.
Heres a part of the code for the IF statements:
Private Sub UpdateConfig_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UpdateConfig.Click
If Choice1Option1.Checked = True And Choice2Option1.Checked = True And Choice3Option1.Checked = True Then
PriceShow.Text = Prices(0, 1)
TextBoxProcessor.Text = Choice1Option1.Text
