Link To A Small Zip File With An Existing VB
Sep 23, 2010
Below is a link to a small zip file with an existing VB (2005 I think) program. [URL] This programs detects if the OS is Locked. I want to make a small edit, and have found the required code for the edit, but I have been unsuccessful at attempting to implement the code. As I said this program only detects windows locks and unlocks. What I want to do, is set it to run an exe when I lock my computer. Doesn't matter what the exe is, just a very basic program.
I however have not been able to find where I need to insert this code. The zip file contains about 6-8 files, I thought I found the if statement where I needed to drop the code but even when I added it to every if that seemed probably I couldn't get any result. what if statement the code I need to add should go into. honestly all I need, I can handle the code past finding that.

I have a workbook (Workbook1) that runs through some steps using visual basic, which ends up opening another workbook Workbook2). Once Workbook 2 is opened, I need to copy a section of data from it, into Workbook1 int a specific worksheet. I was able to do this by recording a macro, but the challange is, the name of Workbook 1, and Workbook 2, will vary by User. When I created the macro it uses the files as they are currently named. The section of code is below.

Is it possible to use VB code to code an application that can merge Hex data from a small (50kb) .dat file with the hex data from another small (50kb) file? This would require designating specific offsets, which I can pre-program, but If I could have user input this would be preferred.
Example.
Hex_1.dat
00 00 00 00 00 11 11 11 11 11 (Offset = 5)
Hex_2.dat
22 22 22 22 22 33 33 33 33 33 (To offset = 5)
Result file
Result.dat
11 11 11 11 11 22 22 22 22 22

i have a small program to get text from a DAT file. the program gets all the text and puts it into a rich text box (rtb1) then I click a button (btnformat) to split the text in the dat file into indexes so that I can output the indexes that I want to an excel file. This program works when I use small amounts of data but if I use say 800 lines of text the program crashes/ can't handle the volume of data and just stalls.

I have a large wikipedia dump that I want to cut into different files (1 file for each article). I wrote a VB App to do it for me, but it was quite slow and crapped out after a few hours of cutting. Im currently splitting the file into smaller 50mb chunks using another app but thats taking a long time (20-30 minutes for each chunk). I should be able to cut each of these up individually if I do this.
Does anyone have any suggestions of a way to cut this file up quicker?

What I'm trying to do is write a small program that copies a file from a USB to another directory so a program already installed on the computer can load this data.Usually copying files from one directory into another wouldn't be an issue.
[Code]...
If possible i would also like to change the code i have written so it just loads January2009.txt from the "root directory" of the USB rather than having to specify H: because if i put the USB in someone elses computer this could change to G: and then it wouldn't work.

I have a small database program that gets data from csv file, I created a function that formats the font color of textboxes based on dates and values.
CODE:
I place this in text changed event and I have a problem implementing it, because the date conversion will not take place until the data is loaded. The second part works but not the first(Date) part.
I can create a button and use its click event to format the text boxes just fine, however i wanted the text boxes to be formatted on the fly . The problem is no matter where i call the function the date conversion wont work.

I know how to write and read files but I can't seem to add 1 to an existing file.
This file currently contains "10" but when I click a button I want it to +1 to that number.
I've tried a.WriteLine(+= 1) but it gives me an Expression Expected erorr which I don't get how to fix or what's wrong with it.
If anyone can help me fix or give another code that +1 to the existing numbere.

I'm looking for a way to (easily, by preference ;)) create a download link to a file on a separate file server.The situation is as follows: the application I'm developing (asp.net 2.0 in vb.net but I have a similar issue in c#, either solution works for me) will be run internally for a company.As is good practice, the file storage and web application are on two separate servers.I basically need to be able to create a download link to a file, the only available URL i have to access the file is servernamefolder1folder2folder3file.txt (can be any sort of file)[code]Which doesn't work for obvious reasons. It used to be set up to write that file to the application path itself and that worked perfectly, but it isn't good practice and that's why I'm changing it (or trying to).I read solutions about creating a download page and then having a table in your DB which holds the links and returns the proper web URL for download but the time constraint I am faced with unfortunately doesn't allow me to develop that.
Assuming I can provide a string with the full filepath to the file like the above, what is the easiest way to just create a link that, when clicked, downloads the document? I have 0 admin rights in this environment. That really isn't helping me. Let's assume I am given the correct link like above and have the appropriate file access rights and such.The above example does work in IE, but not in Firefox and Chrome. IE converts it to a file://servername/... link which does what it's supposed to, but FF and Chrome both actively decided that this is unsafe and have disabled it from their browsers.

Im creating a login system that allows staff to clock in using a 5 digit code. Staff members can also use the "add an employee" function to add a new employee to the Random File.The problem is, everytime i try to create a new employee and hit the save button, the new record writes over the existing records, one by one, everytime the programme is stopped and started up again.
My Question is: How can i get the new record to be saved, without deleting existing records,
Here is the save buttons click method:FileOpen(fileNumber, "C:employee.dat", OpenMode.Random, OpenAccess.Write) 'open the file with Write Access
myEmployee.name = txtNewName.Text 'adds the name
myEmployee.id = txtNewID.Text 'adds the ID
FilePut(fileNumber, myEmployee, n) 'save to the file
FileClose(fileNumber)
