We have developed an application using Visual Basic .NET as the front end and Microsoft Access as the back end. If we run the application on Windows XP we can write records to the database but when we run it on Vista it does not write records to the database.

View 6 RepliesI have and application written that works great on XP. It is VB.Net 2008, using .net 3.5. I install and Access database to the program file directory. In Vista, I get an error that is permissions related as even admins don't have default write permissions to the Program Files directory and access creates a .ldb file when in use. To solve this, I have had the users give themselves permission to the folder.
Is that the best solution? If not, where should data be stored in Vista and in Windows 7? Also, I have an update feature of my software that will download updates to the program files folder. Is this out, too?

Until recently I have been using net 2005 with distributing an app which uses an access database with getting data using recordsets
I decided it was time to upgrade so I got net 2010 & started using ADO.net with a dataadapter.
To my dismay I have found that my app will not run on all platforms, ie XP, Vista 32 & 64 bit, Windows 7 32 & 64 bit From another question I have been told
"If compiled to target AnyCPU, your program will fail to run in an x64 environment if it utilizes any ODBC database driver. In this case, you must compile it to x86. Therefore, x86 is safer than AnyCPU."
Which I have found to be correct I am not familiar with all the options to open a database & the respective code required to extract/change the database data. I also don't understand the implications of using x86 cpu instead of any CPU
MY net 2005 apps have been working fine for the last 6 years (until W7 64 bit), so I want to develop an app that has the same lifespan without having to make variations to the build for specific platforms
I would like the answers to the following:
1. is x86 the new standard for specifying cpu & works on all platforms?
2. why does W7 64 bit have a windows & windows x86 system folder
3. why does my installer when "any CPU" is specified install it in the x86 system folder (W7 64 bit, even though the app fails when trying to open the database as outlined above)
4. which method of opening an access database is preferred which works on all platforms with a common cpu specified?
am devoloping a simple program in vb.net but i wanna do it a cross platform almost (windows & linux) or if there is a vb.net to C++ code converter

View 2 Repliesi have created some shareware applications. I implemented the following mechanism for piracy protection. Before Windows Vista and Windows 7 i did write a dll file to the System32 folder with an encrypted license key. Also in the Registry under HKEY_LOCAL_MACHINE i inserted a registry key.
The problem is that with Windows Vista and Windows 7 due to the User Account Control (UAC) this is denied.
I want to ask : what other mechanism can be implemented ? Where should i store the encrypted key file and the registry key.
I want that the application can be installed for all users of a computer only once.
If i stored the key in the user's application data directory then another user could easily just install it under another user account. Also i do not want to put the key file in the application directory because that would be too obvious.
note that i create the registry key with my application and not with the installer.

View 5 Replieshow do you save data stored in an array of records (structure) to a text file using StreamWriter? I currently have
Private Sub btnSaveToFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveToFile.Click
Dim sw As New StreamWriter(New FileStream("EmployeeDetails.txt", FileMode.Create, FileAccess.Write))
For Each record As EmployeeType In employees
[code]....
but it doesn't work. My array is fixed and currently has 3 elements (for testing purposes). If I enter two records and add these to the structure I get the following data saved to the text file:
123,helen,66000
879,john,89975
0,,0
How do I stop unused elements of the array being included when writing to file? Should I use a dynamic array instead and if yes, how do you use dynamic arrays with structures?

The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data.
