I wrote a vb.net program that can view the documents It uses a reader and decompresses the sql blob to an outputStream and displays the document after a Response.Flush.We sent the code and databases to another group to host this website themselves. They can run the website but when they view the documents the documents open with a page full of small squares.
View 1 RepliesI have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.

View 6 RepliesI have been working on a checker game. So far I have code that allows all the white checkers to move properly. The only problem is that this code is about 5000 lines long. I am sure there is a quicker and easier way to do it.
Here is the code for one checker to move in all squares possible for it to go into:
elect Case str1
Case 1
If picCheckers1.Location.X < 271 And picCheckers1.Location.Y > 114 And Open5 = True Then
picCheckers1.Location = square5
str1 = 5
Open1 = True
[Code] .....
The case is the square that the checker is currently in. I also will attach a zip file of the game so that you can understand it more. There are no errors and everything is working fine but I am trying to find a quicker way to code that doesn't take another 5000 lines of code

I don't do much .Net programming, but I do have one that I maintain, so the answer to this may be obvious.
Setup:
Windows 7 Ultimate with All Language Packs Installed
Visual Studio 2008 Winforms VB.Net project.
I'm in the process of localizing this project, and when I'm making the Japanese version of the forms, the characters display as squares, though they render in my browser correctly. I'm guessing that this is because the default font does not have a glyph for those characters.So, my questions:
Are winforms UTF-8, or some other character encoding?
Is there a way to change the character encoding?
Should I change the font for the Japanese forms, or will Windows do it?
What's the general best practice here?
I want to know that I am copying the characters correctly into my forms, and I want to be able to test them.How can I do this?
Arial Unicode MS does have all the glyphs, but I wasn't using it, because it wasn't in the VS2008 list of fonts. I manually edited the font box to use it, but then Visual Studio throws the message, "Attempted to read or write protected memory. This is often an indication that other memory has been corrupted." I'm guessing that's because VS doesn't have permission to access that font for some reason. I go back to the default font, scary error message goes away.
Then, even when using Arial Unicode MS, the text renders as blocks in the forms titles.Same text renders correctly in labels.I think I want to use the default font, and let Windows handle it. I think I've read that everything from XP on will handle it. Windows 2000 won't, which is a shame, but what ever, I don't know what font I should use, and whatever font it is was excluded from VS.I don't know how to add it without getting lots of error messages about protected memory.Now the problem is, resizing the labels in the form, since the translated text is often larger.
Also, I don't have a support team to do this for me, but I could maybe install extra copies of Windows 7, and change to the Japanese language pack and try to run it.But that becomes a major pain.I thought I read that you could change the language while the application is running, but that doesn't seem to be true.MS docs talk about how to do this, but Windows 7 also tells you that you have to log out to change the language.MS Gothic seems to work, and it's part of VS 2008, but the title bar is still squares. That's really odd, since the same glyphs are in the winform.Is that because title bar fonts are set at a system level, and not the application level?

View 1 RepliesI am making a game based on "Simon" where the computer creates a sequence and the user then has to then replicate it. To create and show the sequence I am generating random numbers between 1 and 4 then based on what numbers come out I change the image in a picture box to simulate coloured squares lighting up. The problem however that I think I am having is that the loop I made is executing too fast as all I see when I run the program is the last light in the sequence. For example is the sequence generated was 2341 all I see light up is square 1. I have stepped into the program and it goes through everything correctly so the only thing I can think of is that it runs too fast to see? [code]
