Hi,

I am trying to call a map from a web application developed in C# in Visual Studio.Net. I have added a reference to dstxInterop.dll, that is included in the C# examples of the development kit for DataStageTx 7.5, to my solution and added the code below:

private void RunDSTXMap()
{
try
{
MFactoryClass imFactory = new MFactoryClass();
imFactory.InitializeAPI(null);

// Load the Map
string sMapPath = ConfigurationManager.AppSettings.ToString();
MMap map = imFactory.MapLoadFile(sMapPath);
map.Run();
string responseMessage = map.GetTextProperty(MConstants.MPIP_OBJECT_ERROR_MSG, 0);
int resuleCode = map.GetIntegerProperty(MConstants.MPIP_OBJECT_ERROR_CODE, 0);
string mapName = map.GetTextProperty(MConstants.MPIP_MAP_MAP_NAME, 0);

....more code here....
}
catch (Exception ex)
{
throw ex;
}
}

However I can't get passed the .InitializeAPI() line and I don't know why!
I keep getting the error message "Initialize Mercator API failed". Can anyone tell me what I am doing wrong?

Thanks

Some quick things to check:

• You need to have your Mercator installation directory (commonly refered to as MERCHOME) in your system path in order to find other needed Mercator DLLs.
• You need to make sure the path to your compiled map (MMC) is correct.
• If your MMC uses the Resource Registry, the MRN/MRC files used must also be found.

What are MRN/MRC files?

I can get the map working from the Command Line Server ok surely the Command Line Server call into the same API's?

.MRN/.MRC are the resource registry files that contain parameters used at run time for executable map .mmc

Where are they located?

I have the SDK for DataStageTx 7.5 installed plus I have the Design Studio installed for DataStageTx 8.0. When I search both C:\Ascential\DataStageTx_7.5 and C:\Ascential\DataStageTx_8.0 the only .mrn/.mrc files found are empty.mrn and testmaps.mrn in this folder C:\Ascential\DataStageTX_8.0\examples\general\rsrcreg

Don't have a clue why this falls over on .InitailizeAPI call no matter what code I run.
