 How to print the current form or a particular file by browsing the window simply by clicking on the button
|
|

You'r going to have to supply ALOT more detail than this. Printing the current form is no big deal, but what's with the "particular file by browsing the window simply by clicking on the button"? What are you talking about here.
Code: Printing a Windows Form (Visual Basic)[^] on MSDN.

Also you're going to have to let us know what version of VB you are using, for 6.0 printing the form is really simple (Me.printform), but in VB NET 2003 it's much more complicated. I had to do a project for a class that printed the form in 2003, utter chaos. I'll post the source later.

Here's what I came up with, it enables print preview, page setup, and printing in .NET 2003:

Hi there,
Actually,i'm designing a IQ test program that include a lot of pictures to be display all together at the same time.And it has a option button to select the answer for each question. At the end,I can calculate the result. After i finish the a question, then i can easily go to the next question just by scrolling. So, i need a form big enough to fit all the pictures.
I wonder if VB isn't the right software to use?Or i need to change to other programming language. Thank you, I'm really grateful if you can help me and thanks again.

VB Means VB6 or VB.Net . if vb.net then enable the scroll bar option in the form property and design your form as big as you want...
|
|
|
|
|
OOO...what is the different between VB6 and VB.NET. Can vb.net complie to an execute file(.exe)?
|
|
|
|
|
Of course it can! Well, all the .NET Framework managed code languages actually compiled to MSIL. When you double click the .EXE, the .NET Framework takes that and translates the MSIL into processor specific instructions on-the-fly.

I have found that Win32_ServerSession in WMI returns the details of users that have connected to a network share. This is exactly the information that I am after, except that Win32_ServerSession doesn't work with Windows 2000.
Are there any API calls, registry locations, or older WMI providers that may supply this information on Windows 2000 machines?
Thanks in advance,
Paul T.

if there are five more folder in the in miankey
subkey1.....subkey5
i would like to have solution in vb6

The solution is MUCH too long to post here. You'd have a better chance at looking at some existing examples, or maybe using an existing module. Google for "VB6 Registry" and you'll come up with tons of examples. Google Results[^]

Hi,
I have 2 windows form . both for startup based on some condition but i donno how to change startup form at run time. I just know that the form which has sub Main method can be used as startup only .
plz guide me in this regard .
|
|
|
|
|
Have you tried adding a Module to your code?
Then you can shift the "Sub Main" code into the module, evaluate the condition, then launch the appropriate form.
Regards,
Paul T.

Omnipass is software that comes with the APC biopod fingerprint scanner. This program can differenciate between password fields and none. This carries over to most software programs and the web. I recently completed a program that requires you to login with a password and i would like to login with the Omnipass software. But the Software does not recognize my form as having a password field on it. I just want to see if anyone knows what i can do to make omnipass recognize my program. Thank you

Since we can't possibly know abou the tens of thousands of controls and libraries out there, you're best bet is to ask Softex.

I've never heard of the product until you posted the question. Then it was a little matter of Googling. It looks like it's a pretty popular product for it's niche market. But that's your problem, it's a niche market product that doesn't have widespread use.

Well, we know less about this medical equipment than you do.
What sort of interface? Do they provide an API? What does their documentation say about writing software for it? Do they give examples? Do they have their own support forum? (That last question may be your best route for an answer)

Here is a datagridview on the winform, which connects to a dataconnector and a dataset.
Now if I edit the cell values and want to save the changes into the database.
How can I do?
Thanks!
|

I don't know if there's an 'automagic' way of doing it, but if you step through all the rows in the grid, you can check their properties to see which ones have been added or edited. From this, you can create database calls to update your database. I use SQL Server ( I notice most VB users seem to use Access ), and that means I can write stored procedures using OpenXML, which allows me to create an XML document that describes an arbitrary number of changes and/or new items, and then process them all in one database call. If you don't have that option, you can still build the SQL to perform the changes, just make sure either way that any text you pass in is cleaned to protect from injection attacks.

Sir,
i would like to ask whether is it the same in vb6,when there is shared function in vb.net such as Getsmstype(),Decodeunicode90()..etc
Can we get the shared function in vb6?
What is override,TP_PID?
i would like to decode received sms..
Thank you

I doubt it, but who knows ?

TP_PID looks like a type to me. override is not available in VB6, VB6 did not support object orientation at all ( in any meaningful way ). In VB.NET, you can write classes, and they can derive from base classes. For example a Ford class can have Car as a base class, which holds methods common to all cars. If Car has a method that Ford wants to replace or add to, it would override that method.
