i have a folder called xulrunner that needs to be initialized - i originaly had the folder under c:\ and used the following code to initialize it. Xpcom.Initialize("c:\xulrunner")This worked fine, but because i want it to get included with the install, i included the folder in the project, and when built it goes to a folder on my desktop, that haves the folder allong with the exe's etc
so i swapped the above code to Xpcom.Initialize(My.Application.Info.DirectoryPath & "\xulrunner")However that does not work.

View 3 RepliesI am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

View 4 RepliesI am trying to display the register contents in a textbox in hexadecimal. I would like to always display 4 characters. The register is 16 bits wide. I have 4 byte parameter variables (param_a_1 through param_a_4) for containing the incoming register value. Because of the way the packet is communicated into the VB app, I pick out the bytes I want displayed and convert them to a string for displaying. The values I get in are not always converted correctly
View 1 RepliesSearching this forum and google turn up things which seem too complicated(more then 4 lines of code), but maybe it needs to be that way.I have two text boxes.

At one point I got it to work but only for numeric characters.

View 13 RepliesWhat's the trailing ampersand on VB hexadecimal numbers for? I've read it forces conversion to an Int32 on the chance VB wants to try and store as an Int16. That makes sense to me. But the part I didn't get from the blurb was to always use the trailing ampersand for bitmasks, flags, enums, etc. Apparantly, it has something to do with overriding VB's fetish for using signed numbers for things internally, which can lead to weird results in comparisons.
So to get easy points, what are the rules for VB.Net hexadecimal numbers, with and without the trailing ampersand? Please include the specific usage in the case of bitmasks/flags and such, and how one would also use it to force signed vs. unsigned.

View 7 RepliesIn my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character. But when I iterate over the characters, the diacritic marks come out as separate characters (as I would expect since this is unicode)However, a u character is different than a u plus an accent for the purposes of this program and needs to be distinguished.
