QuickCAM SDK ConnectCamera2
under what circumstances will the call to the API fail? what are the common cause for this to happen? thanks.
I am definitely sure that i have my QuickCAM installed on my Windows 2000 Adv Srv. But calls to this API fails for some reason (ie. return 0).
Any idea?

I'm working on a VB.net app which requires drag and drop between a ListView control and a Treeview control. The problem is that the selected node in the treeview control doesn't seem to change when I'm hovering over them with the item dragged.
I can't even seem to make this happen programmatically since I can't find a way to get the tree node that the cursor is hovering over (no e.Node in mouseover event 
How can I make this work?
Also, I can't select a nodes by right clicking on them. I need this to display a popup menu specific to each node.
Please please help.

Sorry, can't help you there. I'm familiar with these controls in vb6 but haven't reach that far it .net . Have you tried looking in MSDN?

I looked in MSDN and found the member function GetNodeAt(Drawing.Point) of the treeview control.
Sorry to have bugged you people. 
Should have looked there first.

Hi,
I don't know if this is the correct forum, but let's try...
I have some componente written in VB.Net that is called by ASP pages.
All of them works fine except for one that gives me the "class doesn't support automation" error message. The only help that I've got was "try to contact the application vendor"...
Running it interactively, I have another error message that I'm trying to work around ("The root transaction wanted to commit, but transaction aborted"), but this is a ContextUtil problem.
All the components have the same imports and inherits clauses and same properties in the packages. Any clue?
Thanks in advance,
Molina.

Does anyone know a way to capture a process? What I need to do is when a link is executed capture the link from the process. If possible, to then stop the process before it is fully executed.
I am running a utility which detects for links to other documents ete..I am using this utility to detect links in a certain program which cannot be found programatically through VBA( believe me i've tried! ). So the only other way I can think of is to execute the link, capture the process hopefully with the link and stop it before it fully executes.
Any ideas????
Kind Regards,
Rhys.

hi,
i am using listview control in vb6.
i want to trap event for double clicking on a listview row or item and then open a form. how do i go about it?
|

Hi,
Place the listbox control on your form and give it a name. Then double click the listbox and you will be taken into the code window. At the top of the events window you have 2 drop down boxes; the right hand list is the events list. If you click on this list you will see that below "Click" is "DblClick". You now have the double click event for your list box.
With regards to opening a form there are numerous ways, this simplist being "Form1.Show". You should do a bit of reading of books as there are many ways of doing this depending on your purpose....
Kind Regards,
Rhys.

Rishabh,
Before you go around branding people "idiots" perhaps you should find out what kind of an idiot you are talking to...A+, MCP, MCAD. It was a genuine mistake that I mis-read your post and your attitude towards my mistake clearly shows your intellect; as a result I shall not post the answer you require.
I shall however point you in the direction of some website which might help you in your request; I do not see why I should answer your problem.

And please leave your childish comments for the teletubbies forums. 
Kind Regards,
Rhys.

Hello,
Is it possible to programatically change a folders properties? For example, I have a DFS folder which is currently active on a particular server, I want to be able to change the active server to another without opening up the Properties dialog box. Can this be done in VB6?
Or as another example,
I have a folder "C:\Test" which is not currently shared. Can I programatically change the folders properties so that it is now shared(providing I pass all the correct info) without using the Properties dialog?
My reason is we run on Win2K machines with some 'lockeddown' machines. Certain tabs in the Properties are not viewable to the 'lockeddown' user but I would like to change some settings every now... any ideas or help is appreciated.

Hi !!!
My app, in VB6, is creating a thread to launch a batch file and waiting on this thread to be finished.
Here is the code :
Dim l_lRet As Long
Dim l_lCreationFlags As Long
Dim l_recStartupInfo As STARTUPINFO
Dim l_recProcInfo As PROCESS_INFORMATION
Dim l_recProcAttr As SECURITY_ATTRIBUTES
Dim l_recThreadAttr As SECURITY_ATTRIBUTES
l_recProcAttr.nLength = Len(l_recProcAttr)
l_recThreadAttr.nLength = Len(l_recThreadAttr)
l_recStartupInfo.cb = Len(l_recStartupInfo)
l_recStartupInfo.dwFlags = STARTF_USESHOWWINDOW
l_recStartupInfo.wShowWindow = SW_NORMAL
l_lCreationFlags = HIGH_PRIORITY_CLASS
If CreateProcess(vbNullString, "C:\MyBatch.bat", l_recProcAttr, l_recThreadAttr, False, l_lCreationFlags, 0&, "C:\", l_recStartupInfo, l_recProcInfo) Then
'Wait
WaitForSingleObject l_recProcInfo.hProcess, INFINITE
l_lRet = CloseHandle(l_recProcInfo.hProcess)
End If
My problem is that in the batch file, I lose all environnement variables (Path, SystemRoot), and I have no idea why, because in MSDN, it says that the new process should use the environnement variables from the creator of the process.
Anyone could help me on this point ?
Thank you !

HI,
I have a problem of trying to store URL and retrieving it. I am currently working on a web browser. However I want to be able to control what URL is to be stored using the web browser so as to facilitate offline browsing and faster loading time if I visit the URL again.
Another problem is how am I able to retrieve the stored URL? Does anyone know how to do in visual basic or there is a close reference to it. Thank you.

Sure. It's called Internet Explorer.

Thank you for your answer.
However, what i mean by close reference to it is something that I could see the code and is written in visual basic.

I'm not sure if it's what you want, but maybe the GetSetting and SaveSetting functions are useful? they save info in the registry - very useful for options dialogs etc.
Hope it helps

I am trying to write a windows application in vb.NET that behaves in a similar way to the email selection in Outlook. I am currently doing this by displaying my data read-only in a data grid, but have run into problems with the double-click event not being recognised by the grid apart from on the row header (which I don't want to display). Is there any way that the double-click event can be picked up on the data grid? Any suggestions would be gratefully received.

Does anyone know how I can override the Background Painting of a Textbox in VB.NET? I am currently hooking into the OnPaint / OnPaintBackground but it doesn't have any effect. Basically, I want a Gradient background instead of a Solid Color.

Hello All,
I wrote a com object to suck all the information and process in the dll including submission into database.
My code is:
Dim myobj As New clsMyObj
with myobj
.name = CStr(FirstName) and so on
.ConnectionString = strConnection
.mySubmission
end with
mySubmission calls the function and submit to the database.
What I gathered is that my dll is breaking because of the difference of the datatype.
My question is any way I can check the status of the myobj if the data process is not been submit? If yes How?
I can check the database state by :
Dim myconnection, stat
myconnection = As New ADODB.Connection
If myconnection .State Then
stat = true
else
stat = false
end if
Any thoughts please??
Most greatful.

QUESTION 1: how to choose between VB.NET/C#/VC.NET?
With all due respect, VB.NET seems to have it all:
a. better code samples and documentation... too many examples: DMO/ADO/... I wouldnt want to waste time with C++ trying to figure out some API that couldnt have been so easy to program if proper documentation is available (and in many cases, such docs is available, but to VB and C# only)!
b. speed - not slower than VC.NET isnt it (since all compile to IL)?
c. best dialog editor
d. ease of use (and now it's multithreaded + object oriented)
e. most likely to attract a large user base?
VC seems like an obsolete tool. well, a low level dev tool perhaps (where u want to create buffer overflow). And VB.NET seems like to be the tool that get the job done and done fast.
QUESTION 2: according to code project and code guru forums membership statistics, it seems VC6 is still a much more popular/dominant development tool. but perhaps this is because codeguru and codeproject are both C++ sites?
QUESTION 3: any good sites for VB/VB.NET forums? downloads/tutorials?
What do u think? Correct me if i'm wrong since I do wish to pick the right tool for future development projects.

b C# is as quick
c. C# uses the same dialog editor
d. C# does all that with a decent syntax to boot
e. C# will attract all comers, where VB is for IT Journalists and managers.
f. C# is designed for .NET, where VB is bodged for backwards compatability
