I have created an application using biometric SDKs in VB.net 2005.
Noy I want to deploy it in windows 7 but setup is not working in windows 7. However, its working in XP and xp servers. Is there any way to create a setup for windows 7??

have you tried the setup by running in compatibility mode?
Right click the setup file, select properties, then the Compatibility tab............

Same problem I have faced few days ago. The problem was accessing registry. The Key i was looking for that is common in XP. SO I thought W7 would have that key. But W7 don't. There was no error handler. Then I add a try catch statement which solved that problem.
Ayesha.Hafeez:"I have created an application using biometric SDKs in VB.net 2005."
Try Create another app just having a simple form & try again in W7. If success your 1st app must have some error which are not handled.

Hello, this is Vikash Gohil.
I have a windows service that takes data from the database and does some processing on that data.
I have also added licencing functionality to the service so that people using it will require to register with us. Initially the service would run in trial period and would expire after 30 days.
Now I want the below functionality.
I want to add a User Interface in the Service which will popup when user clicks on SysTray icon of my service. This UI would allow user to Register service using a Licence file on trial period expiration.
And also when registeration form is open, i want the service to pause as i am using sleep command in my service, which will lock the UI if service is running.
Can someone provide me some idea how to do it.
Any help would be greatly appreciated.
Thanks in advance. Awaiting a reply soon.

You don't do this stuff in the Service. You do it in a seperate application that puts it's interface behind the tray icon and talks to the service through whatever interprocess communcation channel you like.

hiya im trying to make a game where a lable(at the moment) displays a value and the user has to drag numbers to add to that amount. I have four PB's 2 seperated by a +
sign and then the therd and fourth by an = sign basicly 1 + 2 = yada. in stead of the lable I want to display the value after the = sign
my idea is to seperate the value into it's tens and units but just cant think of how to do it.
if anyone can point me in the right direction I would be very greatful
sorry forgot to mention im using VS 2008
cheers

How about Sum.ToString()? Or is there more that you haven't mentioned?

You need to try something like this (assuming txtNumberToSplit contains the Number) ,
Dim strNumber As String = txtNumberToSplit.Text
lblOnes.Text = strNumber(strNumber.Length - 1)
lblTens.Text = strNumber(strNumber.Length - 2)
lblHundreds.Text = strNumber(strNumber.Length - 3)
lblThousands.Text = strNumber(strNumber.Length - 4)
lblTenThousands.Text = CInt(strNumber / 10000)
Hope this is what you were looking for.
Happy Coding.
This would be more robust
Dim strNumber As String = txtNumberToSplit.Text
If strNumber.Length > 0 Then lblOnes.Text = strNumber(strNumber.Length - 1) Else lblOnes.Text = 0
If strNumber.Length > 1 Then lblTens.Text = strNumber(strNumber.Length - 2) Else lblTens.Text = 0
If strNumber.Length > 2 Then lblHundreds.Text = strNumber(strNumber.Length - 3) Else lblHundreds.Text = 0
If strNumber.Length > 3 Then lblThousands.Text = strNumber(strNumber.Length - 4) Else lblThousands.Text = 0
lblTenThousands.Text = CInt(strNumber / 10000)

cheers all for the replys I forgot to update the thread
what I have done 3 fuctions but probley reduce them down to one:
Public Function Hundreds()
Dim H As Int16
H = CInt(My.Forms.Form1.lblValue.Text)
H = H \ 100
Return H
End Function
Public Function Tens()
Dim T As Int16
T = CInt(My.Forms.Form1.lblValue.Text)
T = (T Mod 100) \ 10
Return T
End Function
Public Function Units()
Dim U As Int16
U = CInt(My.Forms.Form1.lblValue.Text)
U = (U Mod 10)
Return U
End Function
thanks again for the replys

At the link below, there is an article on this site that provides code to install a program registration system, but the instructions on how to use the code is a bit vague. I posted a question following the article, but thought I may have a better chance of receiving help by posting here. Can anyone provide me with a better explanation on how to install this code into my project?
<a href="http://www.codeproject.com/KB/vb/registration.aspx">VB.NET 2003 User Registration Form (2.1)</a>
|
|
|
|
|
I haven't actually used this code, but reading the instructions, it seems quite clear to me. What is the problem you encounter?
|
|
|
|
|
Thanks for the response. My first thought was to interpet the instructions literally and add two forms to my project. This does not work 1) because the the project can not have two forms with the same name, and 2) the registration program has more the two forms.
I then added the registration project as an existing project to my project. There were actually three projects in the registration program so I left the "About" project out.
Once I set the registration project to be the startup project, the registration program does begin, however it gives me a registration program error, telling me that my computer date has been changed and will not continue. Once I disable that section of code, I can now see the registration menu.
I am now to the point that I need to learn how to have one project call a form in a second project. I will still need to circle back to the date issue because something is clearly wrong there.
Any help on the proper code to have the registration program call my original Form1 when the registratio "Continue" button is clicked would be appreciated.

I have not read said article, however:
- you can freely choose the names of all Controls you use; it is bad practice to keep the names suggested by Visual Designer (such as Form1 and Button1) as these are not functional names within your application domain.
- I see no need to have two projects here, the whole idea is to combine the article's code with yours in a single project.
I suggest you get more acquainted with VB and study the article and its code.

Thanks for your insights. I could rename the forms that have identical names and move them all into my program, but I am confused by doing this. First vb.net has a feature for adding existing projects into the users project (I suspect it is there for a reason). Second, the Registration program clearly has three projects of its own, including files such as Reference and AssemblyInfo which would (I believe) cause problems if renamed or modified. And lastly the Article's instructions clearly state to "set the Form1 (in the registration code) as the startup project". This last piece of information tells me that all of these files should remain as projects.
So back to my question, how does one call a form in a different project?

as long as your solution holds multiple EXE projects, you won't succeed.
if all but one project create DLL files, then all the code can call all other code as if it were one big project, provided you:
- add an appropriate reference to the calling project;
- add an appropriate Imports statetement to the calling project.
Protection code should be integrated in the code it is supposed to protect.
FWIW: if the above is new to you, I don't think your code needs copy protection or license scheming.

Please pick up a book, statements such as

are extremely inaccurate and embarrassing to say the least.
This is not your fault, but you have made it abundantly clear that you do not have a clear and concise knowledge on the fundamental basics of the language to proceed at all.

Hey I never claimed to be a wiz at VB and if I have written something here that has embarrased you, then you've got a problem I am not embarrased to say the I am learning, that I do not know everything, and to ask for help.

While I can appreciate that English may perhaps not be your first language, I still can point out the lack of basic fundamental understanding of visual basic. Your questions are extremely rudimentary & illogical. This is in no way an insult, but you are attempting to complete a task that is above the scope of your intelligence as a programmer. You must learn the basics before attempting to continue. We can give you all the answers in the world, but it won't do you any good as you won't be able to understand them.

Well as it turns out English is my first language and I have a good command of it in both written and verbal form.
You are not a helpful individaul, you are simply mean spirited.
I do not need to ask you what the "A" in EllittA stand for, your behavior has demonstrated what you are.

With respects, between the both of us you are the only one issuing insults.
I kindly remind you that in my original post, I merely demonstrated the fact that you stated that completely erroneous statements and issued a general lack of understanding for the utmost basic concepts of visual basic.
A prime example is stating the the project you downloaded contained 'multiple projects' citing 'references' and 'assemblyinfo' as projects.
This is entirely incorrect.
My advice was simply to begin to understand those basic concepts otherwise you will never be able to completely understand any of the complex concepts or utilize the language, and your potential or skill to its maximum level. If you take this post as insult then I wish you the best of luck selling your software, I'm sure you will be the next Bill Gates.

Peter, I'll try to take a closer look at it and help you out. Unfortunately, I'm away from my desk today and have got no time for looking at it. I will do so tomorrow if you haven't solved the problem by then...

I do appreciate your help. I have also been away from my computer while traving on business.

Hi Peter
I've spent around an hour now trying to incorporate the code into a testapplication, and the result was so/so. It's because I'm running VS2008 and the code is written for VS2003, so slight modifications are needed. I'm confident I could get it to work in another half hour or so and that I would be able to guide you through the incorporation process if needed.
BUT: I will STRONGLY advise you against using this code. I haven't gone through all of it, but what I have seen is poorly organized and poorly written. In several places, for instance he is declaring variables without type (defaults to object), which affects performance of course, plus he's relying heavily on implicit conversion (typical for old VB6 programmers that haven't learnt .NET properly).
As for the security, I'm not sure, but the poor programming I've seen leads me to believe that there could very well be security flaws. One thing is sure: Unless you obfuscate your exe file after using it, it's useless. Then all code (including this licensing code) can easily be decompiled and circumvented.
The author claims he has written the code in 5 hours, and I can certainly believe that.
I've done a similar (but probably a little more complex) system for own my software, and it took me one or two months to perfect.
I would advise you to go for a commercial solution where the licensing logic is encapsuled in an obfuscated dll you can simply reference from your application. They're quite expensive, but compared to writing it all yourself, it's not really worth complaining about.
