Hi All,
I have the application developed in MS Dos Basic 3.0.
I want to convert or reverse engineering that application into .Net 2005 C#.
Kindly provide me suggestion or ways (any kind of parser is available).
thanks in advance.

The only choice you have is to analyze the source code of the app and completely rewrite it from scratch. There is NOTHING that will convert old DOS Basic code to anything in use today.

I've been writing a bunch of little apps exploring various controls, components, etc.I have two minor issues, wondering if anyone could help.
First, when I build the apps to run outside of vb express, they all seem to require internet access to run.If I don't create an exception in my firewall for each app they crash on execution.
Second, When using the FileSystemWatcher object, if I save a file from the internet to the watched directory, I get double File Created events.Is this normal?

Don't know what this is. You don't need internet access to run the app. It would probably depend on what controls you're using.

Yes, it is. The FSW depends entirely on HOW the application is doing the file work. In the case if IE, when it downloads a file, it's downloaded to a temp folder using a temp name, not the real filename. When the download is done, the file is copied to the actual destination folder (Creat event #1), then renamed to its real filename (Create event #2).

Thanks for answering.
Regarding question #1:
The apps in question aren't using any network or internet related controls.Just your basic combination of buttons,text boxes, notifyicon, etc.I guess I'll try a network sniffer and see what they're doing.
Regarding question #2:
If the FSW is only watching the destination folder, shouldn't the file created event in the temp folder be ignored?

That would be my next move.

It is being ignored. The FSW only watches the target folder. When it starts, it enumerates the files and their Created and Modified DateTimes, along with other things. Every once in a while it makes another list and compares the two.
When a new filename shows up or a file with the same name has a new Created time, it fires off the Create event.
If a file disappears off the list, Deleted event.
If a file has a new Modified DateTime, the Changed event.
Now, Renamed is a bit different. The FSW CAN detect a renamed file, but, for some reason, not in all cases. It depends on what the application is doing that is modifying the files. Either the Renamed event is going to fire, or the Created event will fire, maybe along with the Deleted event. It probably has to do with a timing issue when the FSW scans the target folder(s).

Hey all, I'm kind of new to VB so be gentle with me.
I'm trying to write an application that detects a mouse click on a video (target acquisition), working with still pics (jpeg etc.) worked great
but when I play a video (using MMcontrol) the clicks are not detected.
I'm using VB6 (thats what the U offers) and directx9 (on XPsp2)
Thanx in advance , have fun ya all.

I haven't used the MMControl in, what, 8 years. But, IIRC, it doesn't give any Click events for the video window, just the control bar.

Well thanks.
what i really need is a way to detect a click on the video, I don't care which
controller I use, if there is anything taht can make it work I'll take it.
thanks again.

Well, I don't know if it's possible, because I just about never touch DirectX, but if you have the capability to tell DirectX which window to draw in, you can use a PictureBox control as the target window, then handle the Click event of the PictureBox.

You haven't really given us a question to answer. All we can do is refer you to the BizTalk Developer Center[^].

You could move that to a background thread, but it's going to get slower the with more and more text. The RichTextBox wasn't designed to be a colorizer. It'll work, but not good. THe problem is that the user is still modifying text while you code is trying to modify it too. That's not easy to control. Depending on the method you chose to do the coloring and put the RTF back into the RTB, you can be overwriting the changes the user is making to the text, while your colorizing it. Since we know nothing of your code, it's really impossible to say anything other that refer you to an article like this one[^].

Hi,
I have a list of records. Those records have a field called Progress. There are 4 Progresses. 'Pending', 'Work In Progress' and 'Completed'.
If I sort by Progress in ASCENDING, then the order will be:
Completed
Pending
Work In Progress
If I sort by Progress in DESCENDING, then the order will be:
Work In Progress
Pending
Completed
I need PENDING to be at the top. So that all the records which are PENDING will be at the top and the rest can be sorted as normal. Any ideas how I can do this?
Thank you.

Add a new column to the DataTable in memory and set the value based off the Progress column. That way you can set Pending = 1, work in progress = 2, completed = 3. Then in your code take the dataview and sort it.
dim dv as DataView = dataTable.DefaultView
dv.Sort = "NewSortColumn"
Or you could just add a Sort column to your table in the database as well.
Or you could move the Process column into its own table and just stored the processid in your table you are returning.
Hope that helps.

Or sort based on len(Progress) bcos it has the least length.

That's a really bad idea. I'd fire you if you wrote code like that.
What if the status enums change? How about localization changes in the text of the enums??

Sorry , I didn't think on these effects.
Anyway, thank U very much.

Silly me .. I found the easiest and most reliable way of doing this..
Simply add another column in the Database called Progress Number. Pending will be 1, Work In Progress will be 2.. etc..
And then simply sort by "ProgressNumber"
Thank you guys for the help.

Hi,
I have a windows form and I want to print the contents of it. Is it possible to do this in vb.net
|
|
|
|
|
It is.
There is an article here[^] that gives one way to do it, and there is also an MS control that emulates the old VB6 "PrintForm" command in the Visual basic Power packs...

Hi,
Will this work with VB.net 2003. also I can't find the component. Can you help.
Thanks
|
|
|
|
|
It doesn't work with VB.Net 2003 because the code is written with VS 2005 and uses some of the newer language features such as generic collections.
You could just use the compiled component if you have someone who has VS2005 to compile it up for you or move your code to VS2005?
(The component is in the source code attached to the article)
