Since VB6 is a dead language and support for it is waning fast, this[^] is about the best anyone can do for examples.

You have my sympathies. I know all too well what it's like to be forced to do things today, the way the industry did it 10 years ago. Big Grin | :-D

VB.NET and designing of Patch Files

9-Oct-07 4:42

You'll have to explain this a bit more.

The PropertyGrid will only show the properties of an instantiated object. This means you'd have to load the assembly, give the user a list of possible classes to use, create an instance of that class, then bind the PropertyGrid to it.

Hi All

Am new to this subject of Patch files. i have Built Windows Applications and they work fine. Now one of my Clients want to add a Functionality to the Existing Windows Application that i have design before. So i thought of a Patch File but now i have never built something like that before. So basically i need a Tutorial or an Article or Advice on how to build Patchfiles if its the right way to go. if there is another solution, i will greatly Apreciate it

Thanks

Re: VB.NET and designing of Patch Files

depends on what needs to be done and how big you'r programme is

but for almost every programme you can follow the following procedure:
just code the additional functionality into the original project then build and at client side you can just replace the exe and dll files (perhaps with a batch file) and the functionality will be implemented into the application.
if you don't use class projects in you don't need to replace dll's (you probably will not have any)
if all you change is a form then replacing the exe file will be enough

If my help was helpfull let me know, if not let me know why.

Form Control

I have frmMainPage on my project which control everything. Also I have some button on frmMainPage when I click btnMember a form will be loaded on panel2 on frmMainPage( like callfrmMember. I have alredy done this with DAVE's help)

Now frmMember is loaded on frmMainPage in panel2.

Question1: At that moment if I click btnAddNewBook then a Message will be come like msgbox("Please Close Existing Form before you want to open another window") not the frmMainPage.

Question2: on frmMember i have a btnShowDetails when I will click this button then frmMemberDetails will load on frmMainPage on Panel2

Thank You

Are you asking how to do this? Check if your currentForm is Nothing. If it is not, then you put up your message.

Not enough information. What form is Panel2 on?? Is frmMember one of your "control" forms?? Is that also in Panel2?? Why not just have the frmMember form expand and provide all the details instaed of loading a second form to do essentially the same thing.

textbox name txtBarcode, when user will put 11 character then automatically it will call a function getbarcodeDetails(txtBarcode.text)

How will i do it?

lots of ways...
one of them is to get the length of the text with len function (vb6 and vb.net support) if the legnth was equal to 11 so it calls the function.

A.E.K

Sarfaraj Ahmed8-Oct-07 23:47

8-Oct-07 23:47

thanks for ur reply
if txtBarcode.text.length = 11 then
msgbox("Length is 11")
end if

so do i need to write down the code under txtBarcode?

thanks

Dear friends,

I am going to develop a mobile application(related with Camera) in .net.

If we take a picture of the product then it should store the name available in the barcode as its file name.

I dont have any prior experiance on this.. Could you people suggest how can I move forward.

Please help me ASAP

Thanks

Regards

Azeem

I'm not shure I'm getting this

you want to take a picture of a product
in that picture is a barcode
and on the barcode is a name?

and you want to extract that name and use it as a file name

if so that will be next to impossible since it would require you to write code that can read text from a picture.

if the barcode itself is the name and the pic is only of the barcode you can do this but then you will need to know the 'encoding' of the barcode.
--> if this is the case just search the net for 'barcode + vb.net' you should find plenty of examples on how to do this

If my help was helpfull let me know, if not let me know why.

Yes u r right.

But which way I want to go to achieve this. I dont have any idea about. but I have a knowledge in .NET. But new to mobile development.

Thank you for ur timely reply.

The first possibility you have guessed is right but small modification that name of the picture is not inside the barcode but which is at the top of the barcode so I just need to edit it and save it as file name.

Azeem

Tom Deketelaere8-Oct-07 23:06

8-Oct-07 23:06

the problem still remains the same you still need to extract text from an image wich is as far as I know almost impossible to do (if it's typed text it might be possible but still very very difficult) and even if you get it working I doubt it will work perfectly.

My suggestion would be to look into alternate naming for the file but without more specification what you'r programe needs to do and what technolagies you use I can't be more specific

If my help was helpfull let me know, if not let me know why.

thank you very much.

My objective is develop the mobile application which should capture a picutre and save into a particular folder and its name should be the name available in that picture.

This application should run in Win Pocket PC 2003 software. I wish to develop

in Microssoft .NET(I dont know what other tools I need for this like mobile emulator)

We will look into the naming of the file later on or we can make it as a typed file name.

Please help me to start... If I get a way then I will move forward..

Please tell me if you need any other clarifications

Thank you for ur support

Azeem

well if you'r new to mobile development the first thing you'll need to do is learn the framework a bit (the links provide a few post earlier should help with that)
so create a few (small) projects to get the hang of it
after that you will need to see how you can tap into the camera of the pocket pc (can't help you much there never done it before) once you can do that it's simply a matter of taking the pic and saving it.
what you'll need to install (as far as I know by heart):
the mobile framework for visual studio
some sort of syncronisation (forgive my spelling) programme (I always used activesync)
the mobile emulator is handy for testing during development but I suggest you test it with the hardware too from time to time since somethimes there is a differance in positioning the controls (this is a bit trial and error) unless that has been fixed (been a while since I programmed for mobile devices)

that's all (I think)

If my help was helpfull let me know, if not let me know why.
