Replace Function Runs Out Of Memory?
Apr 18, 2012
I don't use VB.Net very much, still mostly do VB6, but I am doing this project in .Net. I have a huge string of data, 168 Mb that I stream in from a file to a string variable. Then I have to perform a number of replacements on it before using the data to compile statistics. Because of the nature of the data, I can't break this up into smaller strings.
The problem is that I get a system out of memory error after a few replacements.
I've used both Replace(x,y,z) and X.Replace(y,z). The second one gets a little farther in the code before it crashes, but they both crash.
When I run it in the IDE, the IDE is using about 130 Mb of RAM, the Exe of the app is running about 350 Mb, and one svchost.exe runs about 300 Mb
Other than that there are no major RAM uses going on. The PC has an i7 980x cpu with 12 GB of RAM.

I have a database with about 180,000 records. I'm trying to attach a pdf file to each of those records. Each pdf is about 250 kb in size. However, after about a minute my program starts taking about about a GB of memory and I have to stop it. I tried doing it so the reference to each linq object is removed once it's updated but that doeow can I make it clear the reference?
Private Sub uploadPDFs(ByVal args() As String)
Dim indexFiles = (From indexFile In dataContext.IndexFiles
Where indexFile.PDFContent = Nothing

I'm running VB2008 on Windows 7; I've written out a ver simple piece of code:
Option
Explicit
On
Module
[code]....
When I run or debug the code, it asks for the First Number and then just completes the running of the program without asking for the second number and uses some random number. The console.readline() doesn't work either, the console window just disappears.

I have a VB .NET String. How can I search that string for a character string and replace it with another string?
For example:
Dim rValue As
String = sproc.ExecuteScalar()
' rValue now has the XML string <indracio fire height=23, width - 6>
/* This is the string that I want to search. Replace the words "indracio fire" with the word "lucion time"
How can I search this string for the words "indracio fire" , and replace with the word "lucion time" ?

I have this relatively short function, triggered when the mouse is moved over a picturebox. When being called, it slowly increases the RAM and PF usage of the program which never recovers.[code]I just wanted to report back and say that I did solve this issue (more or less).I added a manual garbage collection call at the end of the loop and it kept the resources usage under control. It did seem to slightly slow the response time, but it's worth it to avoid the program hogging multiple GBs of RAM.

I am trying to perform calculations on Regex substrings. I would like to do something like (see $2)
lblResult.Text = reg_exp.Replace(txtInput.Text, "$1" & "$2" * 0.039 & "$3" & "$4" & "$5")
I can only do this like:
For Each RxMatch In reg_exp.Matches(Me.txtInput.Text)
Me.lblResult.Text = Me.lblResult.Text & _
RxMatch.Groups.Item(1).ToString & _
Math.Round(CDbl(RxMatch.Groups.Item(2).ToString) * 0.03937, 4) & _

I am using a software that grasp information from web-sites. But I want to something on those information. For doing that, it allows me make a VB script. Actually I have never studied any Vb code. But i found a solution for my project. The data from that website is for exmp. "1.02.30" I want to change first dot into semi colon and the second dot into comma, namely "1:20,30". I found replace function and it works if i want to do "1:20:30" that. But I have to change first dot into semi colon and the second dot into comma.

I am writing a program and I have the Read Function all written out. I need to have the write function. I think is I copied and pasted from the Read function I wrote.
I was able to Mass edit This:
Reader.Position = (&H)
NumericUpDown281.Value = Reader.ReadInt16()
Reader.Position = (&H)
NumericUpDown280.Value = Reader.ReadInt16()
Reader.Position = (&H)
[Code] .....
And there is at least 370 NumericUpDown's. Is there any way to search/find/replace all in one instead of typing:
Find what: NumericUpDown320.Value = writer.WriteInt16()
Replace with: writer.WriteInt16(NumericUpDown320.Value)
Each individually?
The write function will only write properly this way:
writer.Position = (&H)
writer.WriteInt16(NumericUpDown66.Value)
And not this way:
writer.Position = (&H)
NumericUpDown319.Value = writer.WriteInt16()

I have that code running into a windows service and the service seem to have a memory leak, something is wrong for sure. After looking at the whole code, I think it might be inside one of these function but I cannot seem to find where it could be.

I have a VB Function (in Visual Studio 2008 with .NET 3.5) that opens up a connection to an Oracle database and queries the database for information. Apparently after some trial and error, I discovered when the SQL statement is being processed and filling the dataset, it apparently is taking up too much memory trying to complete the task. I'm running into System.OutofMemory exceptions and other unpleasantness.I'm wondering, is there some sort of program out there to measure memory consumption of your SQL code that is being processed in a Visual Studio application?
