C# Signature:

[DllImport("coredll.dll", SetLastError=true)]
    extern static int SipShowIM(int dwFlag);

VB Signature:

Declare Function SipShowIM Lib "coredll.dll" (ByVal dwFlag As Short) As Short

User-Defined Types:

None.

Alternative Managed API:

There's the InputPanel control.

-

Samples:

private void ShowSIP (bool showIt)

{

    inputPanel.Enabled = showIt;

}

private void ToggleSIP ()

{

    inputPanel.Enabled = !inputPanel.Enabled;

}

Notes:

Main benefit of using this over the InputPanel is that there is no control to instantiate in the form initialization process. The main drawback is that you do not have access to the InputPanel.Bounds property. C++ TRUE indicates success. When this function fails, it returns an HRESULT error code.

Tips & Tricks:

Please add some!

Sample Code:

const int SIPF_ON = 1;

const int SIPF_OFF = 0;

public int ShowSIP(Boolean ShowIt)

{

    SipShowIM( ShowIt ? SIPF_ON : SIPF_OFF);

}
