Is there a way from MDL (no native, C only) to pass a powerpoint file name to windows and display it in powerpoint?

Thanks in advance.

Curt

Hello, I need in my MDL app to make a message 'Press ENTER to continue or wait for 5s', but I can not find a way t:

1. catch user press
2. detect if console is a foreground window

This is what I tried without success (code normally works in console application):

      toolSubsystem_printf("Press ENTER to continue or wait for 5s...");

      HWND console_wnd = ::GetConsoleWindow();

      boost::timer tim;
      while ( tim.elapsed() < 5.0 )
      {
        if (
          ::GetForegroundWindow() == console_wnd &&   // does not work in USTN
          ::GetAsyncKeyState(VK_RETURN) == -32767 )   // does not work in USTN
        {
          toolSubsystem_printf("\r\n");
          break;
        }

        ::Sleep(0);
      }

How can I do that?

EDIT: I have also tried getc and toolSubsystem_getStdin but also without success (throws exception due to incpompatibility of FILE pointer)...

Hi,

I want to prevent the user from changing model and I can't find a way to prevent the change made from the View Groups toolbar.

The other ways, such as menu, can be prevented by returning INPUT_COMMAND_REJECT from the INPUT_COMMAND_FILTER callback.

But this callback isn't done, as far as I can see, if the model is changed from the toolbar.

Does anyone know how to prevent the model change in this specific case?

Thanks
Christian

I want to write a macro that covers our printing needs. Part of that macro will need to know which user configuration file is currently in use. Are there any "keyins" or other instructions that I should use to inquire the profile and return a result?

I am looking to set a global origin that finds a corner of a border that is a cell and sets the bottom left hand corner to 0,0.

Hello,

I tried to run myapp by opening MicroSation Developer Shell,  typing cd + path ofmy app then type bmake myapp,  however, I encoutered an error which is BMAKE: Call trace. Note: MicroStation and MicroStation SDK has the same version.

Respectfully yours,

Hello,

I got the source code below from link/forum and I want to run it. However, I don't know what are the steps in creating it into .mke file  or other files like from the delivered example of MicroStation SDK so that I can able to run it in MicroStation.

#include files

#include <mselems.h>
#include <mstypes.h>
#include <msscancrit.fdf>
#include <elementref.h>

Data Structure to Communicate between your Callback Function and the Scanner

// Structure we use to pass data to and from our callback function
typedef struct scancallback_
{
    int    nElements;

} ScanCallBackData;

Your Callback Function

// Scan callback function set by mdlScanCriteria_setElemRefCallback 
int ElementRefScanCallback (ElementRef, void *callbackArg, ScanCriteriaP)
{
    ScanCallBackData*	data	= (ScanCallBackData*)callbackArg;// We're doing nothing but count elements
    ++(data->nElements);
    return SUCCESS;
}

Scan Function

// The scanning function that does most of the work
int ScanForLinearElements (DgnModelRefP modelRef)
{
    UShort              typeMask [6];
    ScanCallBackData    data;
    data.nElements = 0;
    ScanCriteriaP	criteria = mdlScanCriteria_create ();
    mdlScanCriteria_setModel (criteria, modelRef);// Tell the scanner to call our function for each element found
    mdlScanCriteria_setReturnType (criteria, MSSCANCRIT_ITERATE_ELMREF, FALSE, TRUE);
    mdlScanCriteria_setElemRefCallback (criteria, ElementRefScanCallback, &data);// Tell the scanner we're interested only in certain types of element// See mselems.h for the TMSK0_ macros 
    memset (typeMask, 0, sizeof (typeMask));
    typeMask[0] = TMSK0_LINE | TMSK0_LINE_STRING;
    mdlScanCriteria_setElementTypeTest (criteria, typeMask, sizeof (typeMask));// Execute the scan
    mdlScanCriteria_scan (criteria, NULL, NULL, NULL);
    mdlScanCriteria_free (criteria);
    return data.nElements;
}

Hello,

From the delivered MDL Project examples of MicroStation SDK using C++, can I able to debug it or put breakpoint so that I can trace the code while running the program? Please advice how, thank you.

Hello,

with Bentley Geospatial Administrator was created xml file with information. Based on this xml file using Visual Studio 2010 I wrote a small application(Windows Form Application), which has one form with 1 text box and 2 comboBox. But how I could add my appllication to BentleyMap?

Hi Freinds,

I am modifying the Linear elements along with Point Elements (Cell and Text). After matching with target elements by rotation and scaling the elements. It is lossing the Graphic Group and another GGroup will be assigning. So i have tried to implement by setting the GGroup by get/Set. My code  is given below:

mdlElmdscr_readToMaster(&msedSrcElmP, elmDetailsP->ulElmFilPos, elmDetailsP->dgnModelRef, FALSE, NULL); --- Reading

mdlElmdscr_getProperties  (NULL, &uintggNum, NULL, NULL, NULL, NULL, NULL, NULL, msedSrcElmP); -- GGroup

mdlElmdscr_duplicate (&msedNewElmP, msedSrcElmP);

  mdlVec_subtractPoint (&dpSubPt, &dpNewOrgPt, &dpOrgPt);
    
  mdlTMatrix_getIdentity (&tMatrixNew);
   
  mdlTMatrix_setTranslation (&tMatrixNew, &dpSubPt);

  mdlElmdscr_transform(msedNewElmP, &tMatrixNew); ---- after Transforming
    
  mdlElmdscr_rewrite (msedNewElmP, msedSrcElmP, ulCurFilPos); ---   

mdlElmdscr_setProperties  (msedNewElmP,NULL, &uintggNum, NULL, NULL, NULL, NULL, NULL, NULL); - updating the Original GGroup

  mdlElmdscr_rewrite (msedNewElmP, msedNewElmP, ulCurFilPos); - rewriting

Please suggest me to resolve this issue.

Thanks,

Hello

Can someone explain the code inside the red box below? 

Code above was from sir Yongan's example HelloWord. I tried to run the app but I don't know if it scans or what linear element it scan. Maybe if it possible like MVBA we can add message box what Linear element it scans for debugging purposes.

Best Regards,

Aldrin                                                                                

Hi Guys,

Please find the attached Image.

Fig1 : Red Element is the Flood Element Created using the Macro, Flood Element Z Coordinates remaining same for all the vertices as shown in the image(Rotate View).

How can i Assign the Elements Z Coordinates to the Flood Element ?

Requirement : Creating Sharing Edge.

Hello,

I encountered error when I entered bmake -a in MicroStation Dev Shell. See image below.

Using line of code below.

The ouput I want to do is to change the color of line and line string elements.

Hi,

I am getting a nested Cell's level ID using the code below. 

But this code fails because there is Smart Solid header which does not contain any level ID in the element information below.

So, it returns default level ID but this is wrong.

I don't want to test all element types and I think there must be a better way to find a nested Cell's level ID.

// Get level of a cell
void akElmdscr_getLevel
(
 MSElementDescr **edP,
 ULong *levelid
)
{
 *levelid = 0;

 #if defined (MSVERSION) && (MSVERSION >= 0x8b0)
 /*status = */mdlModify_elementDescr2(edP,ACTIVEMODEL,MODIFY_REQUEST_NOHEADERS, naElmfunc_getLevel,levelid,0);
 #else
 /*status = */mdlModify_elementDescr(edP,ACTIVEMODEL,MODIFY_REQUEST_NOHEADERS, naElmfunc_getLevel,levelid,0);
 #endif
}


/* Element function to get level of first element after the header */
int naElmfunc_getLevel
(
 MSElementUnion *elP, /* <=> element to be modified */
 UInt32 *level, /* => user parameter ( level of elmdscr ) */
 DgnModelRefP fileNum, /* => file # for current elem */
 MSElementDescr *elmDscrP, /* => element descr for elem */
 MSElementDescr **newDscrPP /* <= if replacing entire descr */
)
{
 if( mdlElement_getType(elP) != CELL_HEADER_ELM )
 {
 /* Get level of the element */
 mdlElement_getProperties (level, NULL, NULL, NULL, NULL, NULL, NULL, NULL, elP);
 return (MODIFY_STATUS_ABORT); /* Level got, abort process */
 }
 return (MODIFY_STATUS_NOCHANGE);
}

Hi,

On Luxology render screen, I see render result and then saving it using mdlImage_renderViewToRGB() to save the rendered image. But rendered image is darker then Luxology screen. I also tried mdlImage_saveViewToRGB() which gives the same result. When I tried mdlImage_saveView() it always returns MDLERR_CANNOTOPENFILE even file path is true and directory exist.

How can I set both results the same?

Luxology screen rendered image;

Image saved by mdlImage_renderViewToRGB() function;

Luxology screen view;

I store critical data as type 66 level 20 application data. I have a Bentley assigned signature. This works for ALL versions of MicroStation. I have included the V8 code. This does not work in an AutoCAD DWG file with any version of V8 from 2004 thru SS3. I set MS_DWGSAVEAPPLICATIONDATA=ON or MS_DWGSAVEAPPLICATIONDATA=1 but the application data is just not there. Please remember, this is a DWG question. This code works in DGN files and has for several years. Thank you for any help. I have customers that will drop Civil-3D and AutoCAD for design and use Splash if we can resolve this one issue. Also, the Startup record does not work in a DWG file. (P.S. I do not get any of my error dialogs.)

This code is pretty much straight out of the MDL examples of CIRCUIT AND APPLCELEM
