I see all sorts of controls out there to create PDF files. Are there any available that allow you to view PDF files from within a VB app? Also, is there one that will allow you to create thumbnails from the individual pages?
Thanks,
Jeff

Greetings, fellow Columbus developer...
Are you talking about VB or VB.NET? Either way, the easiest way I can think of to view a PDF file is using the Internet control, or just spawning Internet Explorer to view the PDF. As long as the client has the Acrobat Reader plug-in to IE installed, they can view the PDF.

Hi
i've made a connection object with ConnectionString that looks like: "Data Source= C:\...."
the problem is that when i an installation of that program it looks for the database file in the specific location that i wrote in the connection string.
how can i make the connection string so it'll turn to the database in the same directory where the app's EXE is located?

Hi,,
If you use VB6 use App.Path to get the EXE folder.
<br />
"DataSource=" & App.Path & "\FileName.mdb;......."<br />
|
|
|
|
|
|
Dim strPath As String = Application.StartupPath & "\db4.mdb"<br />
Dim Connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strPath
Application.StartupPath being the app's path ( like App.Path in vb6 )
hope it helps.

I am currently implementing an interface that will launch applications based on document information stored in an application I am building. I am trying to support all the popular applications (Notepad, WordPad, Word, Excel, Access, Powerpoint, Project, IE, Adobe AcrobatReader, Winzip, Visio, and FrontPage).
I am using the CreateObject method to instantiate an object for a given application.
set AppObj = CreateObject("<appname>.Application")
Unfortunately, I can't find the proper application references for some of the applications I'm trying to launch. For example:
Set AppObj = CreateObject("project.application") does not work.
Additionally, I need to be able to determine the "Open" method required for each application. For example:
Set AppObject = CreateObject("Access.Application")
AppObject.Visible = True
AppObject.OpenCurrentDatabase fpath
Where can I find this information? Currently, I have the correct definitions for Word, Excel, Access, PowerPoint, and FrontPage. The others however, are a mystery.

If I read what your doing correctly, all your are trying to do is launch an arbitrary application. In that case, all you have to do is start the application using the Shell.
But, for some reason, you are using the automation front ends for these applications. But you don't specify why that is. The flaw in your plan is not obvious, but simple. Most applications don't expose a usable automation front end; Notepad, Wordpad, and WinZip being examples.
Think about it... What is Notepad? Nothing but a TextBox control with a small interface wrapped around it. Wordpad is just an interface wrapped around a RichTextBox control.
In order to help out with this we're probably going to need a bit more information about what you are trying to do and why.

Thanks for the reply.
Yes, I agree with respect to the simple applications (notepad, wordpad). I just listed them all because they are all on my list of common applications used by our users.
However, with respect to MS Project and WinZip, I assumed that these Microsoft products would have some form of object model interface.
The reason I don't want to use the shell, is that there will be instances whereby I will want to control aspects of the application launch that are not readily available through a Shell call. For example, I might want to auto-populate some tagged fields in Word.
Any ideas where I can find the object interfaces for these types of applications (not the simple ones ... but Third Party and Microsoft non-office apps).
Thanks,

Huh?

Well, Word has a COM automation interface, so that won't be too hard.
I'd really like to see the day when all applications have automation interfaces.

Sorry ... I assumed WinZip was a MS product, since that is where I downloaded my last version.
Yes, Word has what I need and it would be nice. Maybe XP and it's XML layer will solve the truly integrated office components problem; however, it is my understanding that it is still a few years away.

Hi.
I would like to know how to link a context menu to a control...
Actually, it's easy to do it with a control like a textbox (in properties, go to ContextMenu and choose your context menu ). But in my case I use an OCX control that does not have contextmenu in properties...
How can I do?
thx!!

Put in a KeyPress handler for the edit control, and add the following code:
<br />
if (KeyAscii) = 13 then ' Enter Key<br />
SendKeys "{TAB}"<br />
Endif<br />
This will trap the Enter key, and send a "Tab" to the form. Need to ensure that next control in the tab order is the next control youwant to go to....
Just out of interest - are you sure this is what you want to do? Not really standard windows behaviour, and precludes the use of enter as OK...

I have a MDI application that has several child forms. On different child forms, I have to open a dialog form that asks for user input and then update that form. The problem that I am having is that when the dialog box is displayed and the user clicks on another window (ex IE, Word, etc) and then returns to my app, when they close the dialog form the window that they were just on gets the focus rather than my MDI app. How do I fix that?
Thanks,
Brian

I'm currently trying to write an application that needs to interface with a 3rd party vb app by automatically 'reading' the text from one of its textboxes into an array in my app.
I do not have access to any of the source code of the 3rd party app and therefore need a method of automatically reading the textbox data from a 'user' perspective.
Can anyone let me know if this is possible, and if so point me in the right direction?
Cheers
Grazza

I have been tasked to maintain a very useful VB6/SQL2000 application that has third party controls (e.g. TrueDB grid, Crystal 8.5), and link to windows applications (Word2000, PMW) looking to have an intranet presence.
I like some advice on what options exist for porting/rewrite, including weighing the cost vs benefits of non .NET solutions that is compliant to our existing mixed .NET/Win32/IIS5.x environment.
In regards to .NET, we will continue to use Framework 1.0 and I understand the conversion tool does not cater for third party controls. Also if we migrate to .NET, webforms appear to be the more suitable implementation and I am concerned about loss of functionality, especially in links to office applications.
To add further complexity to my situation, the organisation has just began to use its acquired Plumtree portal (not yet .NET friendly), and will therefore need some consideration as to whether the next version of this software should be a portal application (gadget is the term they use).
Has anyone seen a good article I should be reading that discuss experience of other pioneers in this field? I would welcome little pearlets of experience even if there is no complete advice or solution for me. By the way, please do not advise me to use a consultancy firm, I do not want to be outsourced as yet

Hello, I've written a service that is using serial communication and ADO.
It is installed on about 20 different computers, and works mostly very well.
In some cases I found a problem. The service is automatically started and is normally working OK at reboot.
On these problem computers it does not start, says error "cannot be started, Could not connect to the Service Controller" and in the event log I get event ID 7000 and 7009.
When I start manually from SCM it fails the first time, and works the second time after a second or two. This is every time!!!
Now I had made an extra service with only one task: make sure the main service is running, checking every minute. With this I thought I could work around the problem.
But not!!!
Now at reboot it first fails to start the "Pilot service" and succeed to start the main service!
This is like 2 tries and fail first and succeed second time...
I have checked the computer at energy saving and so on, nothing is at sleep any time...
Anybody recognize this behaviour?
Please let me know before I go nuts...
