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.

View 1 RepliesI 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()

The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.
