Hello,
I have an application within which I have created a virtual port on which I need to load a Windows Standard 33600 bps modem.
How can I do this through my code or some command line instructions ?
I can not use the Add Hardware Wizard for this job.
regards,
Abhiroop

You could probably use the UpdateDriverForPlugAndPlayDevices[^] function to load the driver by specifying an INF file.

Well, you may download the source code and have a look at it.

I suggested you to have a look at the source code (and eventually modify it in order to play choosen clip).

Hi
I have developed an application in VB6 that uses GMFBridge to have a seamless playback of any number of files in the hardisk. I developed this as a playout solution for a local TV station. What it does is that i have created 2 graphs which are loaded with video files and simultaneosly added those 2 into the bridge and as soon as the first graph finishes the second graphs begins to play and when the second graph begins another file is loaded to the first graph and again as soon as the second graph finish then the fist starts to play and this goes on...by doing this only 2 graphs( two video files ) are loaded into the memory at any given time so by swapping with different files you could play any no. of files in your harddisk. You just need a modification with the code available in GDCL site. Try it. reply me if you have any questions and note that i could only support u in vb6,vb.net or C# and a strict no no for VC++.

Hi
I am trying the samething for a local TV station and GMFBridge is doing almost the thing I wanted but my TV station also has a PCR where they want to play any file in the list randomly as well as list in a sequence. I did try alot but there is some problem in audio is left. When the video changes there are 3 initial pauses in the newer clip audio and by that time it plays well in terms of video. This is the only problem I am left. I just need support in VB only. Please help me.

Hi,
Its been a pleasure to know that someone still uses vb6 and gmfbridge.dll to build video applications.
But  sadly, i would not recommend you to use gmfbridge.dll any further bcz its not at all a stable component. At somepoint your application will certainly crash.
Further more, you will not get support anywhere from internet let alone from its author.
Instead, I would suggest you 2 options i.e either you can develop your own directshow component(you can learn by modifying the GMFbridge.dll source code itself in VC++) or you can go for any third party SDK components from medialooks.
But the second option has its own disadvantages too, bcz i can't assure you a 100% success by using a third party SDK for your unique requirement but you will certainly get someone to help you from these SDK guys so much so that over time your application will get more stable and can add more features as these SDKs get upgraded.
Further more, please be aware that these video based applications are always an expensive propositions. Only a handfull of expert developers are out there in the WORLD who can develop video based apps in a stable and more developer friendly way and no open source component alternatives are available. Infact, who will take pain and hard-work for years without being paid simply to spread knowledge to everyone ?. Of-course, there is VCL player but this player doesn't use Direcshow framework for playing video files and also its activex counter part is not at all developer friendly and no one is using its as far as i know. And if at all someone wants VCL player Framework to create/develop apps, then he MUST learn C++ thoroughly and MUST know the intricate details of how a pixel is lit from a file called "Titanic.avi" 
As far as iam concerned, i have gone to the maximum extend of GMFbridge.dll and failed miserably. Even to this day my mails to its author are still not replied. So if you want any advise(experineced)
in using a third party SDK then pls feel free to contact me at this mail id:manutechalpy308atgmaildotcom. Iam very much interested to know your requirement and will help you as much as i can.

How to link a radio button to a command button to get an answer in the edit box?
example: a 3 radio buttons (10% discount, 5% penalty and 10% penalty) if supposing i will chose the first radio button (10% penalty) how to write the code so that by clicking the command button (compute) a result will be displayed in the edit box and wo with the other radio buttons?
Im new in c++
Thank you so much.

I'm assuming you're using MFC.
Make sure the radio buttons belong to the same group.
You can do this by setting the group property of the first radio button to true.
And the rest of the radio button must follow the first in order.
Now associate an int variable with the first radio button by right clicking on it and selecting "Add Variable".
Similarly associate an int variable with the edit box.
In the button click handler, first call UpdateData.
This will update the UI selection to the variables just added.
Check the value of the radio button variable to determine the option selected.
It will be 0 for first, 1 for second and so on.
Do your calculation and set the result to the variable associated with the edit box.
Finally call UpdateData(FALSE) to set the variables back to the UI.

Superman has given a very good explanation on how to implement this problem. Go Ahead and do the implementation. i am sure it is not a difficult task to complete. When you are stuck there are people to help you.
On selecting the radio button you can pass the value to the function in the command button which does the calculation and display the result in the textbox.

thanks for the reply... my problem is that i dont have a sample code on how to pass the value of the function to the command button. If i tried to use if else statement the system will say syntax error
here is my sample code:
UpdateData();
if
m_button1.Select = true
m_edit2 = 0;
else
m_edit2 = m_edit1 * .9;
UpdateData(false);
i cant connect to the radio button...please help me...
thank you and i will wait for a reply.

Create a Global variable. assign the value and then pass the value to the command button. and why are you using an if-else statement for this?

hehehe...that's the reason why i posted this query because i only have little knowledge on c++. I am still on the process of studying this language. Please sir give me website to where i can look for sample codes on c++. I really need samples very badly...
thank you again.

Search radio button in Code Project. there are lots of examples.
Check this link for example on Radio Button [^]

Lose the calls to UpdateData(). They are completely unnecessary and only add to your confusion. You can easily have a CButton member variable associated with each radio button, and can call the button's GetCheck() method to see if it is checked or not.
BTW, when pasting code snippets, see #5 here. As it is, your code will not compile.

What is this supposed to mean? What is a "command button?"

How to limit the size of dockable pane
|
|
|
|
|
|
If you're talking about MFC, then look at the CalcDynamicLayout and CalcFixedLayout virtual functions of the CControlBar class - look at how CDialogBar handles it.
If you're talking about a .NET/C# thing... then this is the wrong forum.
If you can't tell the difference, then you may need more local help.
Good luck,
Iain.

Hi
Thanks for your reply.
I was talking about mfc.
I am using a CDockablePane Derived class to show a shell tree control. I enabled docking in the left side of mainframe window. I want to limit its horizontal size, so that part of list view area should always be visible. I tried to use CalcFixedLayout() after its creation in mainframe, but nothing happened. Can you tell me how to use it exactly.
thanks
