what is the easiest way to step through a string in this manner... I want to have my program look for one keyword and then another.. in otherwords it needs to find "hello56" and THEN find the word "bob" there are so many places the word "bob" is but I need to locate the "bob" thats after "hello56" Hope this example is clear.

Using F8 to step through all of the code, it gets to this sub, highlites Dim fs and then hit F8 again it just pops up the form, no message boxes - nothing. Other notes: EventList does exist in stated directory.
Any ideas why it wouldn't complete the sub? the first debug line after hit the f8 is: A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll but the file is there

how to read a string in pieces.
Let's say the string is 800 characters long. I want to read 100 of them each time. How do I accomplish this?
Am writing code using VB.net 2005 and am attempting to launch a 3rd party console application and capture stdout and stderr strings. Am able to do this but I find that if I want to capture both stdout and stderr strings I have to wait for the process to terminate before I can retrieve any output data. If I remove the stderr read I can capture the stdout data as its being emitted. Thus it appears that the stderr read "blocks" reading of stdout.[code]Does anyone have any suggestions on how to "un block" the reading of the stderr strings?

View 5 Repliesim trying to read "calculator" from calc.exe, now i found the mem adress where the value resides but i have a few problems
1) how many bytes should i read? im not just talking about calculator string but potentially any length string, i get different results with 4/8 bytes but same from 8 - 32 bytes
2) when i read i get a long value 27866486557179971 but how to convert that into a string
EDIT: ok by staring at the return value long enough i discovered that when i convert it to hex it spells "calc" backwards, same for all other strings, i could build a working converter based on that knowledge but now what bugs me is where is "ulator" or the rest of the string, the most i can get is always 4 letters
EDIT2: oh nm that, by moving memory adress a step further i get the next letter along with 3 previous ones and still backwards but i can work with that
ok so now next step would be making a search function for which i need to find out the range of memory to scan, anybody know how to do that?
I can retreive all items in my notepad but when I am adding them up in my listbox, and trying to print them in the console. I can only display two strings. I don't know why. My string is a combination of a name, space & score. ex: "luke 300". That is the pattern of all strings per line in my text file. I am separating the name and the score using space as the indicator. When ever a space is found, string before and after the space is retrieved and added to the listbox
Here is my
scorelist = New ArrayList
reader1 = My.Computer.FileSystem.OpenTextFileReader(My.Application.Info.DirectoryPath & "scores.txt")

Any example code for reading and writing strings to and from a ControlLogix Processor?
View 6 RepliesAll I am doing is reading each txt file I find in a directory and finding certain strings in the text then counting how many I find in each file and then once each file has its separate counts it send it to a sql database. I have most of it done, but I cant seem to get the count to separate each file so my problem now is that it counts the first file but when it counts the next file it adds to the first file and so on through all the files

There is a lot more to the file reading code, but it's proprietary and this is the part that keeps crashing. It runs fine loading the first two files, but when I try to open a third file, it crashes with EXC_BAD_ACCESS at the input.read((char*)names, numStringBytes); line. I don't see any reason that this should crash. I'm writing the binary files in VB.NET using the below code:

Dim stringBytes() As Byte = encoding.GetBytes("++string")

have been experimenting with new algorithms for some existing classes, do it by copy and pasting code into newly created classes, adding the references then trying to adapt the unit tests till thy pass.Am stuck in a case where the code in the newly created class makes a call to another class (shared by the newly created class and the existing working class) and the IDE won't allow me to step into the code, showing "external code" on the call stack and mysteriously stopping on a non-breakpointed line in the code it wouldn't step into...a line that immediately precedes an error-generating line which i'm trying to trace and debug. In addition the working existing class makes the same call with no error and the IDE allows normal stepping into it

Having a bit of a headache with stepping through a program.
I changed the Keyboard to VB6 in Tools > Options with the same result.
He's what happens.
* I put a break point on Line2. The app stops there and so far so good. * I press F8 or F10 or F11 (tried everything) and the app returns an error on line8 instead of stepping to Line3.
The error is obvious, but I want to step through my program 1 at a time.

View 4 RepliesI have a VB6 object that is wrapped by a .NET class. As far as I recall it is possible to step through a VB6 object (compiled as a library) by simply running the VB6 library and inserting a breakpoint at the desired location.However this does not appear to be working in my case. I have attempted to recompile the VB6 object and re-reference it in my .NET project but this doesn't appear to have helped. there a way to insert Debugger.Launch() equivalent into a VB6 project?

View 2 RepliesProblem: The excutable of the vb program crashes when trying to run but when I step through the program inside of visual studio it runs successfully.
Details: The program performs a winscp.com transfer from a ftp server and then takes the downloaded file and extracts the data from it before sending it to a webpage. The program also decrypts a des3 encrypted file which holds the login details for the sftp server and the webpage.
My Thoughts: I was thinking this could be something to do with the excutable jumping ahead of the slower transfer and decrypt functions thus causing a "file not found" exception to be produced and the program to exit. Lending to this if I slowly (aka spend 10+ seconds stepping through the code) move through the code it works just fine.
As requested Crash Messages:(I capture everything in exceptions and exit properly so no "crash" is reported but the error I get in my logs is as follows:)
1st run with standard test case:Could not find file 'C:UsersAdministratorDesktop..ILC2INFOENC.txt'
2nd run standard case (the file above was not deleted by my cleanup function either as it could not be found)Could not find file 'C:UsersAdministratorDesktop..ILCNETSL10663.csv'
Background:The first file that is found missing is the encrypted login information file while the second file is the winscp.com downloaded csv file.
I've seen this in two different places & can't quite figure it out. I can think of at least two possibilities but don't have a lot of confidence in either.When stepping thru code I encounter the following:
If x = True Then
y = New ContextMenu
Me.ContextMenu = y
[code]....
x is False. The debugger stops on the If & I press F11 to evaluate it. The Debugger then advances to Me.y.MenuItems.Add(z), which is *not* the next statement that should execute. Nor does it appear as if it does execute as, when I press F11 again, the Debugger exits the Sub, as it should. But why highlight it as if it will execute?This is even more confusing in the next example:
If Not Me.FindForm Is Nothing Then
If Not TypeOf Me Is A AndAlso Not TypeOf Me Is B Then
Me.x = "OFF"
End If
[code]....
Me.FindForm is a Form, so it's not Nothing. Me is type A so the 2nd If is False. The Debugger stops on the 1st If, I press F11 & it advances to the 2nd If, as it should. Then I press F11 again & it advances to FatalException in the Catch block. What? Did the attempt to evaluate the TypeOf Me cause an error? It shouldn't, and it doesn't seem as if it did as F11 again exits the Sub rather than stepping into FatalException. So why did it stop there?
My first thought was that the intermediate code got out of step with the displayed source code. I've seen that in other IDE's with interactive debuggers, but usually because those allow you to run the Debugger without re-compiling the code. Not so with VS-so that seems unlikely.My second thought is that it's stopping there because those are the last 'executable' statements in the Sub. But that doesn't really make sense as, in other Subs, it will stop on the End Sub.
I have a data point with a y-value of 1 being plotted, the MS Chart control will use increments of 0.2 on the y-axis. How can I force it to not use a decimal, keeping in mind I will have values of >100 so I can't just force an increment of 1 on the y-axis?
View 1 RepliesI have created a DLL that contains basic functions used in my projects. With the DLL I:Compiled it as a Release Moved the .dll file to another folder Deleted the .pdb files in the binRelease folder When I add the reference of this DLL to my projects and I debug my code, I step through line-by-line and when it comes to a function from my DLL, it actually opens up the source files of my DLL and debugs line-by-line in the DLL source code.
This is REALLY annoying for my purposes and I have tried many things now to disable the debugger stepping into my DLL code. I did a text search in the DLL file and found it stores the path of the project folder.
So far the only thing that's worked is moving/renaming the folder where the DLL project source files are. But everytime I re-build the DLL, once again I would have to move/rename the folder again as it's updated the location of the source.
