insert statement kills my opencursorWithID

John Schenk — Wed, 30 Nov 2016 15:28:39 GMT

Hello, I have a table with MSLINK data, I query my table by using mdlDB_openCursorWithID(CursorId, query) and loop through my data I use mdlDB_processSQL(insert statement) to insert rows into my table. The first insert works fine, but upon the next fetch, the mdlDB_fetchRowByID returns the status of -100. If I comment out my mdlDB_processSQL(insert statement) the cursor again queries through the complete table again.

is it not possible to use the mdlDB_processSQL function within a cursor loop? If not, what would be the alternate method? If so, why would this be erroring? I can cut and paste the insert statement and manually I'm successful with entering the data.

Thanks in advance,

John Schenk

[MS Connect U14 MDL/C++] Replacement for referenceFile.h functions AllowActivation(), Activate() and ReleaseWriteLock()

Tom Torell — Tue, 02 Feb 2021 11:36:09 GMT

Hi,

migrating an old V8i MDL application I'm missing the functions AllowActivation(), Activate() and ReleaseWriteLock() formerly defined in referenceFile.h:

I can't find new versions of these functions e.g. in DgnAttachment.h

Any ideas?

How to get information like copyright, product name, product version on a DLL generated using bmake

Devender Choudhary — Wed, 20 Jan 2021 14:09:41 GMT

Product: Microstation Connect Edition Update 15 and SDK

I have generated a native MDL Application(containing .ma and DLL) build on c++ using the MicroStation SDK's bmake tool. When I look at the details tab on the property page of the DLL, the information like product name, product version, file version, Copyright, etc fields are empty. How to get this information on the DLL?

I came across the generateAssemblyInfocpp.mki file from the mki folder. I was able to generate a file assemblyinfo.cpp using the mki file, this assemblyinfo.cpp file generated contains all the information which I need on the DLL's property page. If this is the process, then how to use the generated assemblyinfo.cpp to get the required?

[CONNECT C++] mdlElementTemplate_getElementParam() replacement

Tom Torell — Mon, 18 Jan 2021 09:45:44 GMT

Hi, I have V8i MDL code using

mdlElementTemplate_getElementParam() and

mdlElementTemplate_getNumElementParams()

Looking for a replacement of these functions, I searched the Connect 10 Update 14 SDK and found:

ElementTemplateParamsHelper::GetEntryCount (UInt32& numEntries, ECN::IECInstanceCR etInstance, ElementParameterType param);

ElementTemplateParamsHelper::GetElementColor(UInt32& color, DgnModelRefP modelRef, ECN::IECInstanceCR etInstance, UInt index=0);

How do I fill the input parameter ECN::IECInstanceCR etInstance?

[CONNECT U10 MDL] No title in a Dialog-ToolBox - DialogBoxDemo Example

Tom Torell — Mon, 03 Dec 2018 13:59:13 GMT

Hi,

actually I'm migrating a V8i-MDL to Connect and had a problem, that my old Dialog Toolbox has an empty title.

I installed

ms10100023en_updt10.exe and
mssdk10100032en.msi

I was wondering, why this little flaw also is shown in the DialogBoxDemo Example delivered with the SDK?

Now I found the solution, that in my code, as well in the provided example, the title is defined in the wrong place:

It was defined in the DialogBoxRsc structure instead of the DItem_ToolBoxRsc structure, contained by the DialogBox.

This corrected code (part of dlogdemo.r) works for me now:

        {IconCmd,           ICONCMDID_DialogDemo4},

I hope this information is helpful for the community an Bentley too.

[CONNECT U10 MDL] mdlBspline_extractCurve() is missing

Tom Torell — Thu, 08 Nov 2018 10:49:08 GMT

Hi,

actually I'm migrating a V8i-MDL to Connect.

Linking my MDL App with mdlbltin.lib, results in a LNK2019 error, Symbol "__imp_mdlBspline_extractCurve" is missing.

This function is contained in msbspline.fdf, so compiling works fine, but mdlBspline_extractCurve() seems not to be compiled into Microstation. It is missing in the ustation.dll, when I open this file with the Visual Studio Dependency Walker.

I have to stroke a Bspline-Curve contained in an element descriptor. In my V8i-MDL I did this calling mdlBspline_extractCurve() first, filling in a MSBsplineCurve structure, and then call mdlBspline_evaluateCurve() to stroke the curve.

How is this task solved on Connect?

Tom

Automated Transverse features

Lars Karlsson — Thu, 29 Jan 2015 19:33:42 GMT

How can I create "batter ticks" (slope tick marks) in IR? I've seen other Civil software doing this automatically.
With IR Generate Transverse Features command it takes me a whole day to do it in my current project (30 km).

[V8i SS3 MDL] Setting the cursor position in Microstation with MDL

Tom Torell — Thu, 15 May 2014 15:17:04 GMT

Hi,

does anyone have an idea, how to SET the cursor position in Microstation via. MDL? I can receive the position with mdlSystem_getCursorPosition().

I want to control the cursor position in a scenario, where the graphical input is coming from a different source as a Microstation window (like a digitizing tablet). Actually I paint a transient element as a "pseudo cursor", but this is not satisfying to the user. I must have control over the real Microstation cursor, while the user is placing a linestring and this primitive command is in dynamic view.

Thank you in advance
Tom
