I am trying to upgrade the btrieve code written by Jim Kyle in the early 90's to VB.NET and am running into a problem with unioned structures. The old C code is as follows:
typedef struct {
union {
struct {
PGPTR PgSeq; // 00 - page number
[code]....
One issue I am running into is that VB.NET doesnt like two struct variables with the same name (Usage). What am I missing to group the overlapping fields with a unique struct name as is done in the C example (v5 and v6)?

View 2 RepliesI am converting a VB6 program to VB express and am having a couple of problems. One of them is a difference in String use. "Result=string$(32,0)" doesn't compile and I tried the trim function, but when I cannot use the "0" with the trim function the program shuts down with the error "Argument 'Start' is not a valid value." I need to replace the "Result=string$(32,0)" with a valid vb express line.

I have 16 student machines who can not access the windows live login during the school hours due to filtering restrictions. They need to register Visual Basic 2008 Express Edition within 30 days or the product becomes useless. The registration process wants them to login to access the keys. Is there an alternative way to obtain the keys as a group, rather than one-by-one?Everything I've found redirects to the 2010 version, but the 2008 version works with our textbooks.

View 2 RepliesIs there an easy way to display the rgb code of system colors in VB2008?
That is, I am looking for some code that will retrieve the names of the colors that are used in the system colors and display their rgb codes (and maybe show a sample), so I could display, for example, what the rgb code for "control" is.
This timer code is for VB6 and worked fine, It's to change the timer seconds into minutes, I'm not sure how to make this work for 2008 though.

View 1 RepliesI have been tasked with upgrading a large web application from .net 1.1 to 3.5. I have converted it using Visual Studio 2008, and it compiles ok. Should I be expecting everything to work correctly straight off? And if not can anyone suggest what are the major pitfalls I should be looking out for. Should I be taking the time to write and carry out a full test for the entire system, or is that overkill?
View 2 RepliesWe are upgrading a VB6 project to VB.NET. I ran it though an upgrade utility (Artinsoft). I guess the question is where is the GUI. In VB6, there is a form designe and Object mode. That does not exist in vb.net correct???
It looks like during the upgrade the entire GUI, the forms, the buttons, they are all gone. None of that was upgraded. So does the entire GUI have to be recreated in asp.net or something?
I'm writing some VB2008 code to control four 7-seg LEDs I bought from Velleman. They came with some example code in VB 5.0, and with instructions telling me to input 5 bytes at a time in the format Chr$() & Chr$() & etc. for the rest of the 5 bytes. When I try to do this using VB2008, it rejects the $ sign, so I've tried it using the Chr() format, which VB2008 allows. However, it doesn't work. Is Chr() the new version of Chr$() or are they different entities? In sending data to the LEDs, I'm using LiveComPort.WriteLine() as my command. (My serial port is called LiveComPort) I also tried it with LiveComPort.Write() asthe command. I know that my serial port and the LEDs are working, because they respond to the demo program provided by Velleman.

I would like to rewrite the code in VB 2008 (or download open source code) to transfer everything to VB 2008. But rather than just putting a picture control on a form as I did before under VB6, I would like to learn and adopt some new technology while continuing to use classic Windows form coding. WPF technology (see [URL] is way over my head.
I recently upgraded an application that creates several report files, that are read by an older VB6 application that i cannot upgrade. I've gotten everything working (faster than i expected) except the new FilePut. I'm saving the ubound of an array, which is a UDT, Then saving the array itself(which again, is a UDT)No matter what I do, the file is about 7 b larger, and doesnt want to read in at all in VB6. For example, I put an 32 bit integer into the file, say 4000, VB6 reads it as 3948395 or so, it seems its padding the file at the beginning or something.
And Yes, i've tried microsofts ArrayIsDynamic function, but it seems to have made no difference at all.
