I want to load a file into this do loop, do i need to write the directory it is in? Also .Net is trying to correct me to write RaiseEvent instead of Load, however when i do this i am told i need an identifier, how do i identify a visual basic form?

Now once I start retrieving more than 10000 records from the table, the loop takes long time to load values into generic class. Is there any way that I can get rid of loop? Can I do something like the following with the generic class?

I have a text file that has a list of image files. I am trying using a loop to load these files onto a webbrowser control and then print them. The code is as following:

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

I'm currently developing an editor for an AFL management sim.I want to be able to load three or four multidimensional arrays to the program, then save them to the same file. I tried the tutorial on here but got completely muddled up. Why can't it be easy like in VB6 When it was like 10 lines of code tops!
View 5 RepliesBefore I begin I would like to mention that I am not a noob in VB, it's just I've never had to do anything this complex before. Basically what I want is to have a program that you can load a txt file in, have it copy key words, and paste it in a textbox so I can use it later on. So in this text file, there is a bunch of info, but I am only needing a certain part. Here is an example of a text file (actually a .dat file, but is easily read):

In a VS2010 solution I have a license.licx file that contains:
DataDynamics.ActiveReports.ActiveReport, ActiveReports6, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff
DataDynamics.ActiveReports.Web.WebViewer, ActiveReports.Web, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff
DataDynamics.ActiveReports.Export.Pdf.PdfExport, ActiveReports.PdfExport, Version=6.1.2814.0, Culture=neutral,
[code]....
If I build the solution on a machine that HAS a license for ActiveReport then everything is fine. If I build the solution on a machine that DOESN'T have a license for ActiveReport I get:
Error 1 'Could not load file or assembly 'ActiveReports6,
Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff'
or one of its dependencies. Operation is not supported. (Exception
from HRESULT: 0x80131515)' LC
On the machine that DOESN'T have a license for ActiveReport if I remove the above lines from the license.licx file then everything builds fine. I always thought that if the license couldn't be found then the unlicensed version will be used but it wouldn't kill the build. How do I get this solution to build on any machine whether it has a license or doesn't?

I want my app to load a .exe file specified by the user, crypt it then save the crypted .exe file on a path also specified by the user. I need some guidance on this. First of all, I am currently using IO.filestream to store the .exe file.

I tried outputting it to a .txt for examination and it was a bunch of tokens as one would expect. Here is the statements:

I have an issue where I need to load a fixed-length file. Process some of the fields, generate a few others, and finally output a new file. The difficult part is that the file is of part numbers and some of the products are superceded by other products (which can also be superceded). What I need to do is follow the superceded trail to get information I need to replace some of the fields in the row I am looking at. So how can I best handle about 200000 lines from a file and the need to move up and down within the given products? I thought about using a collection to hold the data or a dataset, but I just don't think this is the right way.[code]....
