Find "phoneMakeCall" function infomation in MSDN library.

[Anonymous]

I was unable to find that function in the MSDN library. I found more, but they were .NET functions.

I am interested in the same functionality as the tel: protocol. Does anyone know what the parameter is that I can send to cprog.exe so it knows what number I want to dial (if it's possible). And if there is a way to make the phone automatically dial that number would be great.

The tel: protocol is really kind of weak for applications outside of IE. Having to launch a blank window is a horrible user experience.

Thanks in advance,

Hi there

Try this link:
http://smartdevices.microsoftdev.com/Learn/Articles/622.aspx

Discribed is a away to use the TAPI through p/Invoke.
It was a bit of hard work, but after only 1/2 a Day i made my first phonecall to a telephonenumber, stored in my App's database.

Generally i found out, that http://smartdevices.microsoftdev.com is a good starting point for searching information (and of course this forum ;-))

Hi

Thx for the link, It helped me a lot. I didn't get the VB.NET part of the sample code (Downloaded) to work when I was calling a phone number. It seems that the phone is not converted correctly. The SMS part of the VB sample works ok although.

The CS sample work OK, I could make a phone call in minuts, using the sample code.

So if I can't find the reason for the error in the VB sample, I must stick to the CS code.

Details for .Net developers:

The PhoneMakeCall function is not the tricky part of this.
For .net newcomers it's P/Invoke that makes this a little more difficult,
than just using a dll.

1. You have to create a Class (for Example: Phone) that hold the functionality. Because we are using P/Invoke, don't forget using System.Runtime.InteropServices!

2. In your new created Phone Class declare 2 statics, that help us with the option of Prompting before making a call, one of them will fill the dwFlags part of our Infostructure:

private static long PMCF_DEFAULT = 0x00000001;
private static long PMCF_PROMPTBEFORECALLING = 0x00000002;

3. Now to define the allready by yrj mentioned PhoneMakeCallInfo structure. it should look like this:

private struct PhoneMakeCallInfo
{
public IntPtr cbSize;//size of struct
public IntPtr dwFlags;//prompt or not
public IntPtr pszDestAddress;//pointer to CharArray with
//Phone number
public IntPtr pszAppName;//nothing
public IntPtr pszCalledParty;//nothing
public IntPtr pszComment;//nothing
}

4. The import of the Phone.dll function should be no problem:

[DllImport("phone.dll")]
private static extern IntPtr PhoneMakeCall(ref PhoneMakeCallInfo ppmci);

5. Now you have to create a fucntion that instantiates a PhoneMakeCall infoStructure and call the newly Invoked PhoneMakeCall-function.

Now, have fun!
