View 5 RepliesI'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.
'declare 5 element array of prices
Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4}
Dim rateIncrease As Decimal
Dim isConverted As Boolean

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.
I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.

View 2 RepliesI want to read a text file(.txt) character by character into a database.There are 28 characters on each line and I want to read the first 16 into a column in a database and the rest in another column in the database.
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.

I've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...

View 1 RepliesIn my user control's paint handler I iterate over a collection of predefined Bitmap objects and draw them to the client area thusly:

The code works fine but starts to bog down when a dozen or so objects are added to the collection. My question is: Is there a way to speed this up? Would it be possible to use the Win32 bitblt function to replace DrawImageUnscaled? And if so how?

View 2 RepliesI add C# group too in this, because this is not VB problem but ExecuteNonQuery gives timeout. how to increase the time-out?Exact errormessage: ERROR [HYT00] [Microsoft][ODBC SQL Server Driver]Timeout expiredwe do have cms system and in that CMS I have created a IFRAME which calls this ASPX +VB code, which is in different physicall folder and it has managed Pipeline Classic. When I run this in Old application it works fine. But I copied the pages to the news server and created new application pool/website Call OldASPPAGES I get ODBC timeout on 'ExecuteNonQuery()' function below. Sometimes I works but 9 of the 10 cases I gettimeout. I checked the records and there are 247 records. But below you see there are 2 sql statements composed per Each loop. (update and insert)... 2 x 247 records = approx. 500 records.
But since the sql statement is concantenated so 1 call of ExecuteNonQuery, executue does do 500 SQL Statements.... I know this is GARBAGE, unacceptable.... But I inherited so for the moment I can't rewrite that.To the point:Below are the original statemenst: I have just added : conn.ConnectionTimeout = 240As you can see I've added 240 seconds, but I still get timeouts after approx. 30 secs... so this is not the right place.... question:- Why does this statement work in old ASP environment (without problem) and not in this environement in an IFRAME.
