I have just installed vista 64 bit on a new system and put visual studio 2008 on then tried opening an old project of mine. When the project loads it reads from a mdb file and just fills a few comboboxes but when i run it in vista it doesnt read it but in xp which i have on a laptop it does read it.
View 4 RepliesI have an old app, a VB5 front end with access 97 databases all works Ok using the ...program files... folders in XP but I now have a user on Vista and we have problems opening up, and I am braced for problems saving and closing down, if we ever get there.
I sent him a c# applet which found the users folder using string Dpath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
I have moved the data and all settings files to a folder C:Users[Username]AppDataLocal[My app Name][My app data Path]
The start up routine checks a settings file uses the path in the settings to re-attach the front end database to a backend database, test to see if the database uses replication and set the default data path for the rest of the app. we are failing somewhere in here I am sure. I have checked and there are no updateable files in program files
Have I got the wrong path or is there something else I should be looking for?
I have an vs2008 version of the app which is using a similar location but a SQL server database- no problems
i compile my form with the below code when i run it on vista work fine without any problem but when i try to run in on XP cant run... that happened with any XP machine.[code]when i run my exe to other Vista machines work fine... but on xp NO.
View 1 RepliesI am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.
I have a program that can save user's input into a text file and load it back, but whenever I try to open the file and exit without selecting the file I get an error.(if i select the file and open it i don't get any errors).
This is the code that handles text file loading:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
OpenFileDialog1.InitialDirectory = "C:"
OpenFileDialog1.Filter = "Text Files ONLY (*.txt) | *.txt"
OpenFileDialog1.ShowDialog()

The error is :"FileNotFoundException was unhandled. Could not find file at xxx". also I would like to know how to make it so that the initial file name for file saving is today's date. I do not get any errors when I try to save the file.
I need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.

View 9 RepliesI'm having a slight problem getting my program to load a save file when double clicking the save file.I'm using the Command$() to get the command line argument. I can open a save file by dragging it onto the exe. But not by double clicking the save file (after it's associated with the exe).I though dragging and dropping a file on a program and double clicking the file would open it in the same way, but I guess not.So in short how does file association work and how do I get the file path set to a var when the program loads.

I've created a simple dll with VB.NET for a web application, which opens a SaveDialog and write some ASCII-signs to a txt-file. It is working fine in XP.

In other directories I get a permission error.I've red, thatI can give e.g. admin-permission to allow writing a file, but I can give this permission only to an exe-file.

Ok, I'm trying to tackle this topic again. I have searched for setting file associations in the registry, and I only find references to adding the association the ClassesRoot, which, in Vista 64, throws an Access Denied exception.I would like to know if it is possible to set the association somewhere other than classesroot in the registry. Or, if it must be set in HKCR, then the proper way to temporarily elevate the application to perform the registry change.
What should happen is user clicks a button in my program to add the file associations, a Vista security dialog pops up prompting the user to confirm the operation or enter administrative username and password, user confirms, application sets the file associations, then drops back down to regular security.

I have a program that writes unhandled exception detail to a log file stored in the same directory as the program itself. I am wondering how I can have keep the file in the same location, and not have to worry about a file write access. With Vistas User Access Control enabled, the file is not accessible unless the program is run as an administrator, which I don't need it to be for anything else. The file does not exist all of the time, it only exists after an error occurs. Users are encouraged to email the file to me and then delete the file. Thus the file should only exist if their is a error that the user has not emailed. I really want to keep it in the same directory as the program itself, or within a subdirectory of the programs directory, since the portable version is exactly the same program executable and I would like to keep it that way. I am not sure how to go about setting the file security, set it when I create the file if the file doesn't exist, prompting for Administrator privileges to create it with the security. I was also thinking that I could just set the entire folder containing the program executable when it is installed, and then it would be able to create the file without having to have administrator privileges.
View 1 RepliesI'm making a cleaning program and one of the things it does is cleans the recycle bin. How do I do it for Xp, Vista, and 7? I'm on Visual Basic 2010. Also, how do I make it so that it automatically finds the username and uses it when the program deletes a folder. Right now I have it so that you need to enter your username in a textbox and then it uses that for the directories. I know it's something with SystemInformation.UserName.

View 14 RepliesI am using VB.net 2005 and I have a timer running on form1 that communicates modbus with a relay io board. There should be constant uninterrupted communication between the two devices and that is working until I open the data logging form2 and import data from a large sequential text file. While I am parsing data, the timer from form1 stops communicating with the modbus device. Once the data is done, the timer of form1 resumes communication with the modbus device. Is there some other method I could use to make sure the modbus communication is never interrupted.? Is there a command I can periodically run from form2 while the data is being parsed that will keep the timer on form1running?
View 2 RepliesThe following function copies a file from Source & Path to Dest & Path, normally setting file attributes to normal before copying.Yet, a user of my app has reported it to fail when copying readonly files, returning a permissions-related error. The user is however running the code as administrator, and the error happens - quite strangely - on the SetLastWriteTimeUtc line.Although the code reports that the file attributes are set to normal, windows explorer shows that they are set to read only.
