It looks like:
ViewCallback::SetMotionFunction(ViewMotionCallback);
may be the solution...

[CONNECT C++] Determine Cursor Screen Position
If I've got a IViewMonitor set up, does the ViewportP or ViewportP::ViewInfo contain any information about the current cursor location that I can retrieve. I'm attempting to monitor new elements being created with SystemCallback::SetElmDscrToFileFunction(), and I'd like to know the cursor location for some view decorations. I guess I might be able to grab the cursor location (somehow) inside the SetElmDscrToFileFunction() callback, but was wondering if that information is already available to me as part of the IViewMonitor/Viewport/ViewInfo structs. I'm not inside a tool, so I don't have access to a Motion/NoMotion function.

RE: removing proxyelements from Microstation files
Hello all and thank you for your responses,
A little more info - we are trying to convert files from an early Microstation version (08.11.05.17) with an EED plug-in (Bentley Elementary Electrical Diagrams 08.11.00.19) in a large amount of files and thus are trying to do so automatically.
In Microstation we have succeeded to save the MS_DWGSAVEAPPLICATIONDATA = 0, yet when using EED it comes back and the purpose is lost .
Any suggestions?

RE: removing proxyelements from Microstation files
Ido,
My thoughts are you have a new (product based) question related to loss of information during a conversion that would be best asked to the appropriate product support team community first as a new post. If, the question is not able to be addressed and you are able to program to work-around/work past an issue providing a sample of what you currently have (dgn file, screen capt) showing what is expected and what is wrong (dgn and/or screen capt) we will be glad to provide any programming input and guidance we can.

[CONNECT C++] IViewManager::LoadSpriteFromRsrc replacement attempt
Since LoadSpriteFromRsrc() isn't yet available (as of Update 4), I thought I would try to defined a class that would let me load an Icon and use it for view decoration purposes. The Help File states that one can implement the ISprite interface:
"applications can implement this interface on other objects that are able to supply an icon resource."
So I came up with the following class:
struct MySprite : public ISprite
{
DEFINE_BENTLEY_REF_COUNTED_MEMBERS
private:
HICON m_oIcon {0};
public:
MySprite()
{
DEFINE_BENTLEY_REF_COUNTED_MEMBER_INIT
int iconID = 10003; /* IDI_ICON2; */
HINSTANCE myDll = GetModuleHandleW(L"srs_featureOperations");
m_oIcon = (HICON)LoadImage(myDll, MAKEINTRESOURCE(iconID), IMAGE_ICON, 0, 0, LR_DEFAULTCOLOR); //
}
~MySprite()
{
// release memory form LoadImage()
DeleteObject(m_oIcon);
}
void MakeClassAbstract()
{
}
void GetHotSpot(Point2dP hotspot)
{
ICONINFO ii;
GetIconInfo( m_oIcon, &ii );
hotspot->x = ii.xHotspot;
hotspot->y = ii.yHotspot;
return;
}
void GetSize(Point2dP size)
{
ICONINFO ii {0};
BITMAPINFO bmInf;
if ( GetIconInfo( m_oIcon, &ii ) )
{
if (ii.hbmColor) // ' Icon has color plane
{
if (GetObject(ii.hbmColor, sizeof(BITMAPINFO), &bmInf))
{
size->x = bmInf.bmiHeader.biWidth;
size->y = bmInf.bmiHeader.biHeight;
//BitDepth = BMInf.bmBitsPixel
}
DeleteObject(ii.hbmColor);
}
else // ' Icon has no colour plane, image data stored in mask
{
if (GetObject(ii.hbmMask, sizeof(BITMAPINFO), &bmInf))
{
size->x = bmInf.bmiHeader.biWidth;
size->y = bmInf.bmiHeader.biHeight / 2; // monochrome icon contains image and XOR mask in the hbmMask
//BitDepth = 1
}
DeleteObject(ii.hbmMask);
}
}
return;
}
bool GetUseAlpha()
{
return false;
}
};
MySprite m_oSprite;
So, when I try to use my "sprite" (m_oSprite) in my IViewDecoration::_DrawDecoration(), MicroStation immediately crashes. This leads me to believe that I have not correctly implemented ISprite class. I tested my class by calling m_oSprite.GetSize() and returned values that were correct, so I know the icon was successfully read from the DLL. Are there other requirements?

RE: [V8i SS2 VBA] tag element code
Hi All,
My text got chopped from my post, so I am writing it again here. In my above post, I wrote this code and it has some quirkiness to it. Could someone have a look and see if I did anything bad. I can live with the quirk, but I worry that I might corrupt the file if I am doing something wrong. The quirk is that when I use the code to add tagname the first time, the element the tag element goes with won't Undo. That is you can't undo it with the Microstation undo feature. On subsequent uses of the tagname, the undo works. I've included my test project and a seed file.
Thanks,
Minion

RE: [V8i SS2 VBA] tag element code
I see two problems...
[quote user="minion"]
Set td = GetTagSet.TagDefinitions.Add(TagName, msdTagTypeCharacter) td.IsConstant = True
[/quote]
You've defined a tag as constant, but without giving it a default value. The tag value is empty.
[quote user="minion"]
TagMyElement someline, "testTagName", "TestTagValue"
[/quote]
- In your _DataPoint event, you attach the tag to the element (successfully). However, since the tag definition is constant, you can't assign the value and the tag remains blank.
- Remove CommandState.StartDefaultCommand from that _DataPoint event to resume normal MicroStation behaviour.

RE: [V8i SS2 VBA] tag element code
Thanks for the tips Jon.
I've set .IsConstant to false and I've set a default value in the Tag Definition.
I noticed that if I click on the undo a number of times, maybe four or five times, it does undo. Perhaps there is something it is undoing that I am not aware of. I think it's okay now. I will just play with it more.

RE: [CONNECT C++] PersistentElementRef raison d'être
Jon,
You are looking at the published API, which as you know hides more that it exposes.
Rest assured the actual implementation of PersistentElementRef does all sorts of important, persistent-element-specific stuff.
MakeClassAbstract() is inserted by the tools which generate the published API in order to prevent users from accidentally instantiating objects of classes which should not be trivially instantiated.
Regards,
Paul

RE: [CONNECT C++] PersistentElementRef raison d'être
Hi Jon,
Since Transient was already an established item/term; PeristentElementRefs are used for specific cases where an ElementRef is highly likely to incur some remaining changes. e.g. _OnElementAdded (linkage and or dependency changes may still occur) or certain Transaction specific operations are in process where performing otherwise normal ElementRef operations at that point it time would not be desired.
HTH,

Something like

I use NamedView to create the saved views with MS CE.

[CONNECT C++] Converting old hidden line removal code using mdlView_findNamedElmdscr.
I'm porting some C++ drawing creation code where one of the usual operations is to create named views in model and then those views are attached into separate drawing file. One option is to have setting to specify that views is hidden line view, where instead of using the saved views directly from the model, the views are processed to hidden line files and those are used with drawing. The old hidden line removal code uses mdlView_findNamedElmdscr, which is removed from CONNECT. How can this be converted to CONNECT? The CE version needs to behave exactly like V8i version.
Below is simplified version of V8i code to provide idea what the code is doing.
int view_number = 7, buffer_size; ULong buffer[50]; UShort typemask[8], levelmask[8]; MSElementDescr *eldP; UInt32 filePos; DgnModelRefP hln_file; mdlView_findNamedElmdscr(&eldP, &filePos, viewName, NULL, mdlModelRef_getActive()); // Attach named view to viewport 8 if (!mdlView_isActive(view_number)) mdlView_turnOn(view_number); mdlView_attachNamed(viewName, NULL, view_number); mdlWorkDgn_createFile(&hln_file, fileName, DGNFILE_FORMAT_V8, ACTIVEMODEL, SEED_CopyDefaultData, NULL, NULL, TRUE); // Scan design file header information, to be copied into the memset(typemask, 0, sizeof(typemask)); typemask[0] = TMSK0_DGNFIL_HEADER; typemask[4] = TMSK4_MICROSTATION_ELM; memset(levelmask, 0xffff, sizeof(levelmask)); buffer_size = sizeof(buffer) / sizeof(ULong); // Returns a buffer of filePositions of elements that are // of type defined in the typemask buffer and are on a level // defined in the levelmask buffer. dppDrawing_findElementsOfTypeOnLevel(typemask, levelmask, buffer, buffer_size, &nr_found); // Write design file header information into hidden line output file for (i = 0; i < nr_found; i++) { mdlElmdscr_read(&eldP, buffer[i], MASTERFILE, FALSE, NULL); mdlWorkDgn_write(eldP, -1, hln_file); mdlElmdscr_freeAll(&eldP); } // Write saved view information mdlElmdscr_read(&eldP, filePos, MASTERFILE, FALSE, NULL); mdlWorkDgn_write(eldP, -1, hln_file); mdlElmdscr_freeAll(&eldP); // Start hidden line removal // Filemask is set to include master file and all reference files mdlView_hiddenLineRemoval3(preFunction, visibleFunction, invisibleFunction, view_number, modelRefListP, 0.0, TRUE, FALSE, FALSE, TRUE, FALSE, TRUE, TRUE, TRUE, TRUE); // Close hidden line file mdlWorkDgn_saveChanges(hln_file); mdlWorkDgn_closeFile(hln_file); // Close view 8 mdlView_turnOff(view_number);

RE: [CONNECT C++] Converting old hidden line removal code using mdlView_findNamedElmdscr.
The problem is not about finding named view, but writing the saved view to hidden line file. That is, replacing code like below where removed function mdlView_findNamedElmdscr is used to get saved view filePos and mdlElmdscr_read and
mdlWorkDgn_write are used to save it to work file.
UInt32 filePos; MSElementDescr *eldP; mdlView_findNamedElmdscr(&eldP, &filePos, viewName, NULL, mdlModelRef_getActive()); mdlElmdscr_read(&eldP, filePos, MASTERFILE, FALSE, NULL); mdlWorkDgn_write(eldP, -1, hln_file);
