Hi,
Anyone knows how to use login control and how to connect it with the SQl server 2005 and connect to the table within my application database. So it can match the values from the table I have already created in my database.

You cannot install it as part of your .MSI setup project. It has to be isntalled seperately. You'd normally have a Setup.exe that your user launches and this .EXE checks for the .NET Framework and installs it if necessary, then lanuches your app's .MSI setup. Google for ".net setup bootstrap[^]" for examples.

Hi
I have developed an application using WebBrowser control.
In this application the user visits web-sites in WebBrowser control.
Whichever sites he is visiting I am recording all sites along with PostData, Url and Frame information in the collection object.
I’ve kept option to replay the user’s visits. If user wants to see the pages he has visited then he can replay the websites using Replay button.
But I am facing the problems while replaying in following scenarios.
1.If user is visiting the pages and doing steps within same page, ie. He is navigating such that the page remains
same only the data in frames of the page changes. In this case during replay only the page is displayed
while the steps user has done are not displayed.
2.If user is downloading any file from website then while replay that download-file step is not replayed.
Please tell me what can be solution for these problems.

Hi guys,
I really need help...
I'm searching for a VB or VBScript code that can print PDF files... I've searched and tried lots of VB code available in the net but none of them works. Or maybe I just don't know how to run them.
Kindly help me about this issue... I'm not really a VB guy but I'm required to used this language. I'm also looking forward to study this language and your guidance will be a great help.
Please give a me functional code that you have tried.
Your help will be highly appreciated

You need some kind of component to do the printing for you. There is nothing in VB6 or VBScript that can do this on it own.

If you haven't been able get these to work, how are we going to explain it to you so you understand it?? We'll be telling you the exact same thing you've already seen.
monmagallanes wrote: Please give a me functional code that you have tried.
There's no chance of this happening. CP is here to help you with your own code, not write it for you. Besides, without the components to do the printing, like Acrobat Reader, any code anyone gives you is worthless.

I have this code (see below) that looks promising...
I run this whole command independently and it runs successfully but when I used it for my new code it displays an Compile Error: Variable Not defined at the following line:
AcroDDEFailed = False
txtAcrobatDDE.LinkMode = 0 <-----------------------ERROR
txtAcrobatDDE.LinkTopic = "acroview|control"
txtAcrobatDDE.LinkMode = 2
By the way, my code who call the function to print is the following:
Sub PrintAdobePDF(sFileName As String)
Dim PDFArray As Variant
ReDim PDFArray(0 To 0)
PDFArray(0) = sFileName
PrintPDFs PDFArray
End Sub
I also have Adobe Reader installed on my PC. And also, as i said earlier, the code below successfully printed a existing pdf file.
Please help me with this issue...

The error says that you don't have something called "txtAcrobatDDE" defined anywhere. From the example code you posted, I'm assuming this would be a textbox control named "txtAcrobatDDE".

hi. how can I convert a string to integer? I'm doing a program in VB were you are required to input a
mathematical formula in a single input box and value each of the integer. But when I use the Left command,
the formula of the textbox are converted into string type and won't compute the value as in the formula
indicated. I really need your help. thanks..

There is nothing built into VB.NET or the .NET Framework that's going to evaluate expressions typed into a textbox. You have to create your own expression parsing engine to break the input down into something you can do the math on, piece-by-piece. Google for "Reverse Polish Notation" for an intro to expression engines. There are certainly other implementations to do this, but RPN is good place to start.

Hi,
If U want to convert text in to integer then simply U can use it:-
<br />
dim s as string<br />
dim i as integer<br />
<br />
s="200"<br />
i=val(s) 'This function converts the string in integer<br />
<br />
<br />

Did you read the OP's question? He said the text box contains a "mathematical formula".

Have you considered looking at this[^] article to get an understanding on evaluating formulae in a textbox. I know it's in C#, but using a tool like Reflector it's relatively simple to revert the IL into VB.NET.

I'm doing a project entitled "SMS Environment for Bus Time Arrival". What it means is that a user can SMS to the server asking for what time will the bus arrive at that particular bus stop. I've done the SMS part but I do not know how to extract the bus information from the database and how to create the database. Hopefully someone will be able to help.
Mistreated.

Since you don't have a database, that's going to be pretty difficult.
Mistreated wrote: Hopefully someone will be able to help.
There isn't enough information to tell you much of anything other than gather the requirements for your database. What pieces of information are you going to track? How do these piece relate to each other?

If you are part of the SBS team, you will be provided the information on how to retrieve the information from their server.
If it is a school project, you wont be able to get the actual information from SBS. What you can do is mock the bus arrival information (DateTime, Bus number, ETA of certain bus stop) and put them in a database, if the main focus of the project is the SMS part, not the arrival prediction part.

Can you help me with the codes of how to extract the information from the database? Lets say i mock all the bus information such as the arrival time and the location of the bus stop.

Some ideas which may help !!!
Bus stop data: Stop name is not unique. There's probably 100's of 'High street' . Also there will be a bus stop on the other side of the road. Each stop must have unique ID.
Time tables : In most cases are not 'rich' enough and the published one's are full of cryptic codes like FO - Fridays only. Even worse will be the subscripts (1) - 'Only runs on market days'
Bus number: Every bus Co. will have a 1 service. So in even in your area there may be several same number buses. Make a Service number unique example FR001 - for the First service number 1.
Routes - You will need a route. Time tables mostly give 'Timing points' leaving out intermediate stops. Don't assume each Bus no 1 goes the same route. Think about school runs.
You will need to simplify this very complicated situation but highlight in your project where you have simplified and why..
So you should have a minimum of three relational tables Bus stop, Bus, Route.
Each query will take the form of "What is the next bus stopping at this bus stop" or "What is the time of the next number 1 at this bus-stop"
Hope this not to confusing.

What is the difference between typed and untyped data sets?
Which one is better to use?
I think I should use typed datasets. Am I right.
