I will do a program then save it and close it out but when I go back to open it it won't open. It just sits there. I'll click on Recent Projects and they won't open. I'll click on Open Project and select a existing file and it will just put it in Recent Projects but won't open it up.
View 2 RepliesThey are all working on my computer,but they are not working on any other computer(I tested it on about 10 computers). They are working when i start making it,but after they are not working. When i try to run it on other computer it is not opening(there is not any error message), or there is a crash report(application crashes). So they are working on beginning of programming, and after they aren't.
View 1 RepliesI am currently writing a program in VB 2008. Here is what the program is intended to do: I need it to have two forms of input, so I want it to open existing text files and create new ones. Once the user has selected what input to be taken (either a file is opened or a new one is made, guessing multiple forms need to be used here) the user will then take the text file either created or opened and then be able to click a button which will sort all the text in the text file into alphabetical order and then display the results to the screen. While this happens, I need the words in the file to be counted by a counter (so a loop i guess) that then displays on which line each word appears on. I then need this information to be displayed in a text box on screen.
View 2 Repliesfirst, what is the base minimum that windows needs open to run... ex. svchost.exe, explorer, etc.
Second. is there an easier way to close all programs except the ones i want to stay open, i want to keep the needed basics open and my program, which will open other programs, but i want to make sure nothing else is running so that things will go as smoothly and as fast as possible. I just don't want to manually check what processes need killed and place them in the program one by one, i want to kill all but a few.
Extra credit... stopping all unneeded windows services would be nice too, but that would probably be too long of a process to worry about, and not really worth it considering the benefit of speed it would give.

View 3 RepliesUsing the new Visual Basic 2005 Express Edition Beta.Created a project, form, controls, etc. Worked great. Love it, compiled perfectly.Saved everything, closed the program, went to bed.

I can open the code, it's all there, exactly as I left it, but cannot get back to the designer mode to (easily) add more controls to it!F7 just opens the code, right-click just gives me code option, not designer option.This is amazingly frustrating..
View 1 RepliesI want to open an existing VB class file, add a few properties and close it again.
Simple enough, I thought: Take the CodeDom, a VBCodeProvider, parse the code (using the Parse-method), then identify the location where I want my stuff added (doubtless using some nifty LINQ expressions), add a bit of code and then have it generated and here we go.
Now I see that Microsoft apparently added the Parse method only for the fun of it but never implemented it.
What's the story here? Can I only generate code from scratch? Is it not possible to load existing code?
I want to use my word add in to open an existing file, the code is:
currentDoc = app.Documents.Open(currentFile)
where currentFile is a string containing the path to the file I want to open, when ever this code runs, there are no errors, but I also cannot see the document
edit: the program first closes the 'currentFile', adds something to the package, then tries to open it again with the line above, when it closes the document the word application stays open with no document in it, but when it opens it again it is not seen in the application, but the document is open

I have a program that runs some data manipulation on a file when it is double-clicked and then displays this to the user.However, when I double click on the same file type of a different file it opens in a separate instance of my program instead of the same instance already running, i.e. some message that says would you like to reload file, YesNo, and then given the answer perform the action required.I have found some code to stop a second instance from opening, but this is inconvienient for the user to close out of the program everytime they want to view a new file.[code]

In my scheduling app I am exporting information to an excel file. When the first export runs it opens a new instance of an excel workbook. I have decided to save each schedule (AMRN, PMRN, AMTech, PMTech etc) to separate works sheets instead of appending the first worksheet. This way when the shedules need to be printed the whole workbook can be selected to print. When I try to open the existing workbook if it exist I get an error. Here is what I am trying to do.

I am sure this can be done, as Visual Studio is basically built this way. What I want to do is simply make a class that my other workmates can use. But rather than have it in a code form, I want to build it (partially), and then my workmate can add it into their programs (sort of, like the add reference for the .NET stuff).

View 1 RepliesWhen you've finished a program and you're trying to distribute it to the mass public. How is the best way to go about doing this? What sites would you post your program on and getting the word out that there is a new program on the block and it does xyz. This is directed to freeware so there wouldn't be any advertising.
Sorry for not explaining it very well the first time.
I have an application the contains several excel files bundled with it. I'm not opening the files and processing them within my application. These files contain a data-connection to reload all of the pivot-tables within each excel file. I have a 'link' on my form, that when clicked, it determines which file to open and calls a sub using filename and executing Process.Start(filename) for any excel file I want to open. I have no problems opening any one of the files and then exiting excel.
The problem is when I 'close' a file, but don't exit Excel; then try to open another file(clicking link on form)... it creates a new instance of Excel.
I know from experimenting that the fileopendialog form will 'reuse' an existing Excel instance, IF it does not already have a file open.
How can I do the same thing without using the fileopendialog?
I don't want the end-user to have access to the folders where these files live. That's why I have multiple 'links' on my form, one for each xls that already exists. I just want them to be able to click on a link and the xls file opens AND if they choose to merely 'close' a file and not exit... Don't create a new instance of Excel, but re-use the existing one.
I am trying to move my programs from VB6 to VB 2008 Express. My initial problen is with getting data from my Jet database. I've searched for samples but haven't been able to find anything to help me. I would like to be migrate the Jet database to the vb 2008 system.
View 3 RepliesI have a Windows Form Application which has been developed in vb.net 3.5. It is a charting program and shows stock market charts to users. Now I have made another program in vb.net (same .net version) and I want this program to interact with the one I made before. The new program is like a small scripting language. So for example: if I run a script then its output should be reflected in the other program. How can the two programs communicate ? Both will be running on same systems. No remote stuff. I mean passing arrays,strings or possibly structures.
Plus I have several functions which are written in first program. Is it possible for the other program which is an .exe also to call the functions of the other one if I make sub/function public or something. The reason is we can calls functions or subs if we include a dll. But can one exe calls functions/sub of another exe (if both program are in .net).
the only way I can get reading from an instrument is through proprietary software. even though it is connected with USB. the instrument - a Cary 500, with a GPIB interface.the problem is with instrument commands, like "reset" or "change wavelength" or "instrument reading" They reside inside a primitive Basic shell provided by the instrument software. I'm looking at expencive National Instruments, is there another solution with VS/NET?
