View 4 RepliesI have access to the source code of a previously created app that work's as designed, but i am looking to update it for further enhance its ability. The change required may be simple in thought and also in design.Basically the app allows you to read in a data file a confirm the data file is in the correct format.Details fo the data file. All lines of the file are 120 characters long. If they are not then there will be an error returned. The fields within the lines have different properties and vaules and the validation on these fileds and lines work perfectly.
1. The first line of the file is always known as a descriptive ( header record ).
2. The next line will outline a detail record. The could be hundreds of these lines.
3. Finally there is a file total record.
A file could be four lines in total or 40000 lines in total. As mentioned the app works when there is one header and total record.I am looking to see if it can be modified.My intention is to merge multiple data files into a single file. There in lies the problem. There is a line in the code as per below.
Do While Not EOF(1)
As far as i can tell this means to go to the end of the file. When there are more than on set of data , there are errors messages generated because the code is looking only for one set of header and trailer records. As mentioned when there is one set of header total records , the apps will validate the file and return any error messages.What i think i need to do is insert another loop/s that say's read data between the header record and the trailer record , if there are any errors display it , then go to the next header / trailer records and display and errors , and continue to do so until you reach then EOF.

I'm trying to make a mastermind game program with visual basic. I started of creating the combination maker for the start of the game. Hoever, in my version i don't want any colors to repeat. I used the random function independently to get numbers from 1 to 6. Each number has a corresponding color. The problem, the values still repeat sometimes.
Here's my code for that part:
Randomize
a = Fix(Rnd * 6) + 1

How do I (programmatically) find out the key repeat delay and key repeat rate for a system?

I'll explain..I have two apps A and B, B is kind of a reminder application which runs in the background..but that is not important here, thing is when App B is open, it has a button which takes user to App A, I am doing that using Process.Start("A.exe") all good so far. Problem is I need to make sure that if any other instance of App A is running then I need to jump to that instance. I am able to check for the instance running using Process.GetProcesses() but I am not able to set focus to that running instance.

The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).

also if i try to re load the form that was created by the main process i will get exception saying you can't change one some that was created by another process

system.Diagnostics.Process.Start _ ("c:winamp.exe") if winamp for example is installed on another pc in another location i want to run it from my program but i want there to be sort of like a settings.txt file where you can edit the path to winamp and my program should first read the path set in the settings file and then open accordingly. how do i go about doing this?
btw it would be great if you could point me in the right direction for making a windows form where one can edit the settings file within my program without editing the settings file in notepad

This code should read the string "34,56,23,74,69" from a process's memory addresses (in this case notepad), right now it works but very slow and I think it even breaks somewhere. My problem is with the ReadProcessMemory function. I can't make it read an entire mbi.RegionSize into the buffer. I tried everything and now, it only reads 1 byte at a time until the mbi.RegionSize is finished then it checks if the text that was read contains the text I need to be found, then it goes to the next mbi.RegionSize. Now, even with notepad which is very small it still takes 10 seconds to find something and I intend to use it with a much bigger program, so it will take like forever. Another problem is that it only finds the string "34". If I put "34,5" it won't work.

I'm new to these forums but am really enjoying reading the various posts. I have a question regarding string to date converting. I have the following string from a file I need to convert to a valid DATE in VB, but I am unable to with the attempt's I have tried. The date is: "Thu Dec 13 10:00:06 2007" So I am assuming it is something like this in VB: "ddd MMM dd hh:mm:ss yyyy" The code I am using is the following to test against an array to see if the date is encountered, once it is I want it to convert it to a VB based Date.

I have the code below (found on forums) that should read the string "34,56,23,74,69" starting from the first address of another process till the end. However when I start the project I receive this error :"PInvoke restriction: cannot return variants." With Search Engine for example, the string is found, displayed and changed without any problems. Right now I have a subroutine that searches the string but only if I put the right memory address, and unfortunately the address changes almost every day.
