View 2 RepliesI have a program written in VB.NET which stops a service that uses file x, modifies x, and restarts the service.
I have modified my code for testing so that it just reads in the file as a string and immediately writes it back out.
Shell("net stop " & SERVICE_NAME, , True)
Dim myReader As System.IO.StreamReader
myReader = My.Computer.FileSystem.OpenTextFileReader(x)
fileString = myReader.ReadToEnd()
[Code]....
The stopping of the service is no problem, and modifying the file is no problem, but when the service starts it stops immediately because, as best I can guess, the file is in use. Even when I try to start the service manually, it stops immediately. However, I found that I can open file x, click save without modifying anything, close the file, and start the service and everything works correctly.
If I comment out the writing part, everything works fine.
Also, the file I'm modifying has a .conf file extension. I don't know if this is relevant.
I am using a number of localised form resource files in order to store translation strings. In addition to the standard component captions and text values, I am storing localised messagebox strings for things like autosave notifications.However, when opening the form again, the additional messagebox strings have been removed from all the form resource files.Is it not possible to store additional strings in these files? Or is there a workaround?
View 2 RepliesI'm going to be using a text file to record and save values, line by line, and then pull these values out again upon restarting the application. Almost like a save file of sorts, just for some basic numeric variables.Getting the information in and out won't be too much of an issue, however I am wondering if there is a way that during the installation of this application, I could specify a place to create and save this text file, for eg:
c:ProgramFilesPOSxstocklevels.text
I have VS8 Professional, so I do have the Setup Wizard tool, which may allow me to attach files.
I have an exe which I am wanting to deploy to my userbase.

View 5 RepliesIm using a keyboard hook in an application to capture 'hotkeys' pressed.The idéa is that if the user of the computer presses ctrl + alt + 1 then Sendkeys.Send("string of text") should execute and the string is sent to the focused window.
However - the user still is physically pressing ctrl + alt which disturbs the string being sent in sendkeys.
Is there a way to programatically release/disable ctrl and alt keys in the code just before sendkeys, and enable it again after sendkeys.Or - is there a better way of sending the string of text without having to disturb the keyboard?

View 2 RepliesI've been trying to send a test-version of my program to the person who has instructed me to create it.Now, the problem is, every method I try seems to fail, either by crashing on start-up or saying it requires Visual Studio to be installed.I've tried giving him the '.exe' from Debug, Release and it just crashed the moment you start it up. (And Windows automatically starts looking for a solution but of course finds none.)
And if I use the "Publish" function and put it in an install, that's when it says it requires Visual Studio to be installed.Is it so difficult to distribute something made in Visual Studio? :< I'm probably overlooking the obvious here..
Well, I've searched numerous threads and I'm stumped. Though my VB.net experience is newb status.I'm interacting with Excel Workbooks/worksheets with:
Imports Excel = Microsoft.Office.Interop.Excel
Now I'm fairly adept with getting data from the excel sheet with no problem.But each and every time I quit my widows form, or execute a new command_button click to repeat an operation, in the task manager, excel.exe then opens up a new instance.Releasing the the Excel COM object seems to offer a bit of head scratching.I realize that you can get your form to activate and retrieve data from whatever spreadsheet has been directed to be opened, but I can't seem to put it back and close it correctly.I have read about the Marshal. release object methods and garbage collection with no luck so far.Do I need to import another liberary that completes this operation? I would asssume this would be taken care of as apart of the:
Imports Excel = Microsoft.Office.Interop.Excel
close excel instances opened up by my windows form? Somethig like this:
Dim xlApp As Excel.Application
Dim xlWorkBook As Excel.Workbook
Dim xlWorkSheet As Excel.Worksheet
[code]....
(so that it is no longer looked at as "read only" when the spread sheet is opened up from directly from excel)As A minor work around, I've teminated it from the task Bar with proc.kill() but this does not help because my ultimate goal is to just simply realease the excel sheet when my windows form is finished getting its data.This following code does not seem to work.
releaseObject(xlApp)
releaseObject(xlWorkBook)
releaseObject(xlWorkSheet)
I wrote an application in my free time that helps people create certain files when they want to create a custom level for some game. The application of course is completely free, I made it for fun and to help the community. That community has now requested that I also release the source code of my application, in case I stop being interested and they ever want to fix some bugs (this has happened loads of times in the past in the same community, there are loads of good applications out there with some small annoying bugs where the creator has gone missing and the source is unavailable).
Therefore I would like to release my full source code, but not before consulting here how exactly I should do it..I could of course just zip up the entire Project folder and upload it, but I feel that is probably not the best way to go about it..

I need to refer to some strings using an "indirect string" in the registry. It should be in this form:
@filename,resource
MSDN: "If the resource value is zero or greater, the number becomes the index of the string in the binary file. If the number is negative, it becomes a resource ID."How can I find out either of these numbers for my resources that only have names in VB? I also need the ID/index for the exe's icon.
I have some questions about mysql database; I have set up columns and rows on mysql database and I would like to make mysql connection for a test before I would release the project in the near future, but my doubts is that how would I be able to keep mysql admin username and password details secure in the project without anyone could find out??Secondly, I don't want anyone to crack my project to get the details, which it will put me and other clients at risks.

View 2 Replieswhen i add a few resource files and add them in go to debug i get this error
View 9 RepliesI recently picked up the VS.net 2008 Trial, looking to possibly buy it. I added a splash form, and not even the default code works. First, I got the error "'My' is not defined". I went under my project, clicked the resources tab, and it asked me to create a resources file. So I did. Now, 'My' is defined, however 'My.Application' does not work. I'm assuming I simply have to add Application as a resource, just as I did with My.Resource. I'm not sure how to do this, and I apologize if this has been asked before. I did do a search but it yielded no results. 'My' was a bit too vague and returned no results, 'not defined' was a bit too vague and returned a bunch of results
