ASP.NET - Concatenate String Memory Leak?
Jun 16, 2012I am supporting an application, which uses lots of String concatenations and I believe this is the cause of a memory leak which eventually causes an OutOfMemory exception. Please have a look at the code below:
Public Sub ConcatenateString() As String Dim Test1 As String
Test1 = "Hello"
Test1=Test1 & "my"
Test1=Test1 & "name"
[code]....
I believe there are nine Strings in memory at line ten as String is an immutable object, but only one reference to the String Test1 that contains: "Hello my name is Joe Blogs what is yours?". My question is; are all of these Strings picked up by the garbage collector when they go out of scope? i.e. when the sub routine finishes running. I seem to have a memory leak and am thinking that I should really be using a StringBuilder object.

View 4 RepliesUse The ToString Method And A Counter To Concatenate A File Name Into A String Variable From The Image.FromFile Method?
Dec 18, 2010I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

Concatenate A Equation And Answer To Text Box?
Mar 22, 2011In our school theres a programming class and the teachers gone for the week and the sub is starting to get very frustrated, so I offered to help in any way i can. I have never programmed Visual Basic but I have programmed Ms-Dos, Javascript, HTML, *.vbs, *.ahk, *.gml, and a variety of other languages.
The class is going to build a program that calculate how many rabbits are born in a family. So when they click the button it shows in a text box the actual equation and then the answer after the equal sign that where i assume concatenation comes in.Here's the code I've thrown together for when the buttons pressed:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim RabitAmount As Integer
Dim ShowEquation As String

I got the equation to answer it self and show in the text box but it won't show the equation?

Dynamically Concatenate Public Variables?
Mar 10, 2012This seems basic but here's my problem. I am trying to build my connect string as a public variable that will connect to either an express version of SQL Server or a non-express version. The app.config defines it as being express or not and is modified to the user's choosing when it is deployed using the a firstRun routine.
The problem is that even though I'm modifying the value of the variable SQLexpress when the app is initiated which in turn should modify the value of the variable g_strConnectionString it doesn't. The value of g_strConnectionString will always take on the initial value of SQLexpress. I know I can define 2 separate variables for the connection string but I'd prefer not to have to change all of the references throughout each of the various programs in this system as they all have the same issue.
So in the following load event I've traced it and when it sets globals.SQLexpress = "", I then look at the value of g_strConnectionString and it still contains "SQLEXPRESS". It seems I need to somehow force vb to refresh this variable after it's been changed.

Concatenate Multiple Files Into One Large File
Aug 16, 2009[Code] each file is about 30 kilobytes in size, and they contain raw hardware statistical information in a comma-deliminted format. I want to do the following with these files as my end-result.
NEWFILE.CVS contains the contents in this format:
metric_group_001 metric_group_002 metric_group_003 metric_group_004 etc.
I don't want APPEND, I want to concatenate the contents of these files into one large master file. I am able to do this MANUALLY, but I need to have a DYNAMIC method of doing this because of the number of files will change depending on the test we are doing with the hardware. This is the code I am using to do this process manually and it does work, but I need a DYNAMIC method in place. [Code]
