How do I fill the comment and percent complete

[Steve_Block]

I'm using CVI. How can I fill in the comment and percent complete entries from my code?

Hi,

take a look at this Example shipped with NI:  ...TSFOLDER...\Examples\DisplayingProgressAndStatus\UsingCVI

I see this uses a UI message. This one works but I'm still trying to figure out how to create a custom control for this usage. I see the following from a help page:

http://zone.ni.com/devzone/cda/tut/p/id/4532

"Other messages can be sent by the programmer to update progress and status on the Operator Interface. When you post a message, you can send string data and/or numeric data with the message.

You can define your own events by using an event number that is greater than or equal to the value of the UIMsg_UserMessageBase constant (10000). There are two parts to using custom UIMessages:

· Posting the UIMessage
· Receiving and handling the UIMessage

"

How can I assign an event number to an activex control that I create on the server side?

HI Steve

I have added to the UI shipped with NI the ProgressText and a 10000+1 Message

See the attached Code

Works so far. Thanks. Here is my next question? How do I post information from TextExec to report back to the DLL?

HRESULT CVICALLBACK ApplicationMgr_OnUIMessageEvent (CAObjHandle caServerObjHandle,
                              void *caCallbackData,
                              TSUIObj_UIMessage  uiMsg,
                              VBOOL *cancel)
{  
    char lpcstrBuffer[256];
    char *pCharBuffer;
    enum TSEnum_UIMessageCodes eventCode = 0;
   
    TS_UIMessageGetEvent (uiMsg, NULL, &eventCode);

    if(eventCode >= TS_UIMsg_UserMessageBase) {
       4; // My break point
    }
   
    if (eventCode == TS_UIMsg_UserMessageBase+1)    
    {  
       
        TS_UIMessageGetStringData(uiMsg, NULL, &pCharBuffer);
        sprintf(lpcstrBuffer, "I Have received Message:%s\0", pCharBuffer);
        TS_EngineDisplayMessageBox (gMainWindow.engine, NULL, "USER Message", lpcstrBuffer,
                                TS_MsgBox_Custom, 0, 0, NULL);
        GetStringData(uiMsg, NULL, &pCharBuffer);

        // This is where I would like to try posting back to the DLL.

    }
    else if(eventCode == TS_UIMsg_ProgressText){
//      TS_UIMessageGetStringData(uiMsg, NULL, &pCharBuffer);
//      SetCtrlVal(gMainWindow.panel,MAINPANEL_STR_PROGESS ,pCharBuffer);
    }
    else if(eventCode == TS_UIMsg_ProgressPercent ){
        // DO YOUR STUFF HERE  
       
    }
        // IF MORE USE A Switch/Case

   
   
    return 0;
}

Hi,

Some years ago, i tried this with sending Messages to TS engine but this would not work well.

But now i do it with accessing the TS-Variables. Which is working well

Try this:

But I'm doing everything without using variables. What is the equivalent of TS_UIMessageGetStringData that posts data so the function TS_EngineGetUIMessage can read it? This function returns an object instead of a string. How do I extract the string from the object?

Hi,

Question?

 where do you do  in your sequene the polling  of UI Messages. ?
Thread? Execution? Callbacks?

Please post a sample 

Greetings Juergen

[Steve_Block]

I do it in the DLL with three lines of code.

   local_err = TS_SeqContextGetExecution(teststand_data->seqContextCVI, &errorInfo, &execution);
   local_err = TS_SeqContextGetThread (teststand_data->seqContextCVI, &errorInfo, &thread);
   local_err = TS_ThreadPostUIMessage(thread, &errorInfo, TS_UIMsg_UserMessageBase+2, 0, ".", VTRUE);

I need to figure out how to use TS_EngineGetUIMessage or the equivalent of TS_ThreadPostUIMessage which lets me read.

[Steve_Block]

How can I do this in .net?
