ATEM C# Macro control

i am working on a project in c#
i am trying to make a program that has 6 buttons.
each button needs to fire a macro on the ATEM.
i am stuck.

i have connected to the switcher. step one done.
i can not find a command to quary the switcher for a list of macros in the switcher.
i all so have not been able to set up a processes that works to implement the IBMDSwitcherMacroControl
i am failing at the callback....
i am not a great programmer, a beginner with c# in fact, i have a few things under my belt.
i under stand the steps but not the correct processes.

i have three days on this and am running out of time. this switcher goes out on the road again.
this is not something i have to get done before it leaves. i will just loose access to it for testing.

i am just trying to understand this thing well enough well i have the gear in the shop to work with.

if any one can shed some lite on this i would be thankful
for the help.

Hi John,
Like you I'm not a programmer but struggling to build a library so I can automate ATM from Windows PowerShell. (https://github.com/imorrish/atemlib which I branched from another project to get me started)
Just started trying to add macro support, so far to get existing macros ,I have deduced from the API...
public uint GetMacroCount()
{
this.Connect();
uint macroCount;
IBMDSwitcherMacroPool switcherMacroPool = (IBMDSwitcherMacroPool)this.switcher;
switcherMacroPool.GetMaxCount(out macroCount);
return macroCount;
}
public string GetMacro(uint index)
{
this.Connect();
string macroName;
IBMDSwitcherMacroPool switcherMacroPool = (IBMDSwitcherMacroPool)this.switcher;
switcherMacroPool.GetDescription(index, out macroName);
return macroName;
}
Don't have access to an ATEM to try this until the weekend but always complicated getting callback defined but basics for run should be...
public int RunMacro(uint index)
{
this.Connect();
IBMDSwitcherMacroControl switcherMacroControl = (IBMDSwitcherMacroControl)this.switcher;
switcherMacroControl.Run(index);

thank you,

i will dig in to this soon. i may not have time today.
but i will start on this ASAP

thanks again

Well, surprisingly that worked for me (gives me even more motivation to keep learning C#).
Difference might be that from PowerShell I'm running in single-threaded apartment (STA) but I know Winforms don't. It would pay to look at the BMD SDK C# sample application as to how they did the simple transition button.

What would be really nice if BMD provided a full c# class library exposing all functionality. No doubt I'm doing it all wrong and will probably have to rework once I know better (anyone want to help?).

Hi, wondering if anyone could help me with this. I would like to integrate the Macro control into a client I'm working on. The client will control a CasparCG server and an ATEM 2 M/E switcher we have in our studio. The only thing I really need to do on the ATEM 2 M/E is the code to run a macro. For what I understand I will need to first connect to the switcher and then the code to send the command to run the macro. I've already added InteropServices and BMDSwitcherAPI to the code but I do need helpwith making the connection to the switcher.

Just so you know, I am a beginner C# programmer . . . .

Here's the full code of the client

                int serverPort;
                String server;

                // Retrieve textbox values...
                server = servertextBox.Text;
                serverPort = Int32.Parse(porttextBox.Text);
                Console.WriteLine(serverPort);

                //Create a new connection object...
                con = new CasparCGConnection(server, serverPort);

                //...and establish a connection
                con.connect();
