View 5 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.
I have come across to develop an application for Windows 7.My program has one setting file and one LogFiles folder under the same folder as EXE. User will change some setting from Program and the values will update in this file. If there is an error, error detail will log in Logfiles/ todaydate.txt file.(Later I discovered/learnt that I should not edit/write the files to Program Files/sub folders.)So, now I'm trying to move these two files to another location. After searching a few on Net and I got the following result.[code]When I make Setup project for my application, I have to put the Setting file under one of these location.And what I found was, I only has a choice of "User's Application Data Folder" which is equivalent to My.Computer.FileSystem.SpecialDirectories.CurrentUserApplicationData.If i put Setting.ini file under this folder in Setup project, it gave me an warning of "File 'Setting.ini' should not be installed into a User's Profile folder because it may not be available to all users."
View 4 RepliesI am trying to write a VB application that will talk with USB Printers. After seaching far and wide, I have come across a wiki that I think may be what I am looking for, but the examples are written in C, which is absolutely not my thing.I would like to use the functions SetupDiGetClassDevs, SetupDiEnumDevice Interfaces and SetupDiGetDeviceInterfaceDetail included in setupapi.dll to retrieve the devicename of the printer so I can then call CreateFile() from kernel32.dll to get a handle on the printer I would like to use. I'm not sure if the steps I've mentioned are the right way to retrieve the device name (hardcoding in a device name doesn't seem to work, so I'm assuming this is the only thing I can do). The main problem I am having with those functions is that I do not know how to call them. As I mentioned, I referenced a wiki, which can be found here, but I do not understand the parameters and structures etc.. that I need to pass in order for this to work. Can someone please explain the parameters (namely where to get the first parameter for SetupDiGetClass Devs), how to define the structures etc...If it matters, this is all the code I have for this task

View 1 RepliesSince VB 2005 express does not really install properly in windows 7, here is how to get it to install and make it work right. It's very simple.
1. Right click on the VB 2005 express installer file and click "Properties" in the menu.
2. Now click the "Compatibility" tab.
3. Check the box that says, "Run this program in compatibility mode for:"
4. Click the drop down menu and select "Windows Vista Service Pack 2. (I haven't tried service pack one.)
5. Now check the box that says "Run this program as an administrator" and click "Apply," then "OK"
6. Run the installer.
Wait until VB 2005 express has installed to do these next steps.
7. Make a desktop icon for VB 2005 Express
8. Right click on the VB 2005 express icon and click "Properties" in the menu.
9. Now click the "Compatibility" tab.
10. Check the box that says, "Run this program in compatibility mode for:"
11. Click the drop down menu and select "Windows Vista Service Pack 2. (I haven't tried service pack one.)
12. Now check the box that says "Run this program as an administrator" and click "Apply," then "OK"
VB 2005 Express should now run on you Windows 7 machine! (Yipee) Notice that it is necessary to repeat the same process for the installer file as well as the actual VB program becuase they are two different files and need to run in compatibility mode.

View 3 RepliesI will be googling this but in case I don't find it easily, here is my question - how do you install a windows service that you've developed on your own PC to a server? Is there an option to produce the package (I thought it was an msi file) which you can run on the server?
View 1 RepliesThe app Im working on is dunning on an embedded xp machine. It recieves input from the serial port from an industrial process, and then a backgroundworker class calculates and updates the single form GUI with the results from the process. Very simple.Now, the customer want to allow automatic download of log files by an USB memory. The process should work like this:
1)User plug in an usb memory
2)SHow a virtual keypad (touch screen) where the user enter a security code
3)If code ok, show a 3 choice screen, if not ok show error message and allow the user to try again.
4) If user choose the "export all" button, this choose form will close and i display another form with a progress bar that show how all files are copied to the usb memory. When this process is complete, I will display teh form that says "remove the usb memory and press ok to restart the application.
As you see here lots of forms are created and disposed based on user choices. My biggest issue here is that I have no clear design pattern to work from.For example.. should I have this "chain" in the main gui form, or should I let each form create the next form. For example on the "select action" form, when I press export, should this form create and show the "copy progress" form, or should all forms be created and destroyed from the main gui form?
Also, such an issue like with the password. I put it as a constant on the main form, to avoid "magic numbers" in the code. And then I ran into problem because the "keypad" form is created on another thread and I can't access the costant on the main form, so I got a cross thread exception.Everything starts when an USB memory is connected. And the OnConnected eventhandler is running on a different thread than the main UI thread. how to design this chain of window creation/deletion is greatly appreciated. I show all forms with the SHowDialog because I dont want the user to be able to close the form unless he/she presses a button. And not by accident press somewhere else.

View 3 RepliesI have created a Windows Application using VB dot Net. It has many Forms. The user shall be able to open many forms at a time. I want to provide a "Window" menu functionality to the existing application.

The functionality should be similar to any Word file's Window functionality.
Active window must be tick marked.
I'm creating a program to stop a particular windows service.This windows service was also written by me.The service will watch a folder and cut and paste the file to another location.The service was running OK.And I have another (TESTING) console application which will try to stop this service only. (I'm doing testing!)However, the app failed to stop the service.
Here is the code i use to stop the service.
VB.Net
' AutoMover is my windows service name.Dim controller As New ServiceController("AutoMover")controller.Stop()controller.WaitForStatus(ServiceControllerStatus.Stopped)controller.Start()
The debug line stop at WaitForStatus because the service didn't stop.Here is the Stop function from my windows service
VB.Net
Protected Overrides Sub OnStop() GC.Collect()End Sub
After a few seconds (may be 1 minutes or 2), there is an error message box pop up from window and said the following error msg.' Auto Move is my service Display Name.Could not stop the Auto Move service on Local Computer.Error 1053: The service did not respond to the start or control request in a timely fashion.If I click Stop from Services.msc, it stop successfully.

View 3 RepliesI write program for Windows CE that should work with Serial ports. I use object System.IO.Ports.SerialPort. Everything works well but when I close program and open it again, I receive error: Port is in use! At the end I write:
port.close()
port.dispose()
And If I add this:System.GC.collect() than everything begins to work But problem is that computer gets stuck when garbage collector is called for each port. If I tried to use collector somewhere else, it doesnt "collect" ports and they look like used if program starts again.
I am just wondering if you people will be able to help me make my application autload on windows startup (Like Windows Live Messenger does), I have been researching on the internet and I cannot find anything for it.
