So how did you get it to open the drawings?

I moved the open part outside the dialog call, like you said.  I got all the information I needed when closing the dialog, stored it in a global array, and use it outside of the dialog.  Then I used the 'open' method on the 'DocumentManager' (document collection) with the name of the file, and the bool value set to true, so it opens it as read only.

After a test, it doesn't work correctly if I cancel the dialog, so I'm going to have to change something, but that is not my main concern right now.  Right now it is the plotting that I can't seem to figure anything out on.  I'm reading the ARX help files, but they are not helping.  :ugly:

I seem to be not using my 'PlotEngine' correctly.

My search continues.......

You're using the DocumentCollection's Open method...could you post the relevant snip of code please.

Sure.  'PlottingArray' holds all the info for my plotting right now.
Code: [Select]
try {
tempDoc = DocCol.Open(PlottingArray[i,0], true);
using (DocumentLock DocLock = tempDoc.LockDocument()) {
if (string.Compare("Model", LayoutManager.Current.CurrentLayout) == 0) {
IsModel = true;
}
else IsModel = false;
if (PlottingArray[i,5] != null) LastPlot = true;
StdScaleType ScaleType = (StdScaleType) Enum.Parse(typeof(StdScaleType), PlottingArray[i,4], false);
MyPlottingPart(PlottingArray[i,1], PlottingArray[i,2], PlottingArray[i,3], ScaleType, IsModel, LastPlot);
}
}
catch (System.Exception ex){
MessageBox.Show(ex.ToString());
}
finally {
if (tempDoc != null) tempDoc.CloseAndDiscard();
}

It is defined in the main program portion of the code that is called by the command name.  If you want I can post that whole portion, but didn't think it was needed....... well I will post it, as it is almost all posted above.
Code: [Select]
using AcadApp = Autodesk.AutoCAD.ApplicationServices.Application;
DocumentCollection DocCol = AcadApp.DocumentManager;
Code: [Select]
[CommandMethod("MyPlot", CommandFlags.Session)]
public void MethodCall () {
DialogResult dr;
using (MyPlot modalForm = new MyPlot()) {
dr = Autodesk.AutoCAD.ApplicationServices.Application.ShowModalDialog(modalForm);
}
if (dr == DialogResult.OK) {
bool IsModel;
bool LastPlot = false;
Document tempDoc = null;
DocumentCollection DocCol = AcadApp.DocumentManager;
for (int i = 0; i < (PlottingArray.Length / 6); ++i) {
if (PlottingArray[i,1] != null) {
try {
tempDoc = DocCol.Open(PlottingArray[i,0], true);
using (DocumentLock DocLock = tempDoc.LockDocument()) {
if (string.Compare("Model", LayoutManager.Current.CurrentLayout) == 0) {
IsModel = true;
}
else IsModel = false;
if (PlottingArray[i,5] != null) LastPlot = true;
StdScaleType ScaleType = (StdScaleType) Enum.Parse(typeof(StdScaleType), PlottingArray[i,4], false);
MyPlottingPart(PlottingArray[i,1], PlottingArray[i,2], PlottingArray[i,3], ScaleType, IsModel, LastPlot);
}
}
catch (System.Exception ex){
MessageBox.Show(ex.ToString());
}
finally {
if (tempDoc != null) tempDoc.CloseAndDiscard();
}
}
}
}
}

Edit:  I had to lock the document while trying to plot it.  Before I locked it, it wouldn't work at all.

Tim,

Immediately after this line:
Code: [Select]
tempDoc = DocCol.Open(PlottingArray[i,0], true);

can you put in a MessageBox call and spit up the the name of MdiActiveDocument please?

It showed the name of the drawing I selected to plot, not the one it was called from.  It even plotted it.  :-)

What happened when you didn't lock it?

The reason I ask is this. I tried using your open approach first and it wouldn't work because the Open method is asynchronous - meaning the line of code executes, then it trucks on and doesn't wait for the drawing to finish opening. So this approach went out the door very quickly. I then settled on COM to open the drgs, but always wanted a better way. Then Alexander Rivilis posted a bit of code here on using P/INVOKE to get access to a synchronous open method.

I don't lock the drawing to plot though, whereas you do...

When I didn't lock the drawings, it would act like it was plotting, but then nothing would show up at the plotter.  I mean the window for the plot progress dialog would show, but it wouldn't ACTUALLY plot anything.  Once I added in the dock locking, it plots.  I don't understand it really, just reading in the ARX files made me think it would work.

Actually, after looking through my plot function, I do in fact lock the document to plot it...sorry.

I'm still intrigued as to why your open is working though........hmmmm......

Thats fine with me.  I'm still learning, so questioning why I do things is not bad for me.  It makes me think why I did it that way.  :-)

I can post the whole thing.  I will just use a file instead of the code window though.  I'm on '06 and using .Net 1.1.  I had to change the ext to 'txt', so I think you can just change it back.
