TaskDialog user input

[dwightduronidavy]

Dear all,

The following application macro (for Revit 2024) does not allow the user to input using the TaskDialog function. 
I would appreciate a resolution concerning this matter.

Hi @dwightduronidavy ：

Taskdialog just a prompt text window , if you want to get user input paramater value , can use the ` Microsoft.VisualBasic.Interaction.InputBox` API top make this style like the picture.

this dll reference import from `Microsoft.VisualBasic.dll`

and i edit you code , also have some problem.

1. you function not use in startUp

2. the activeDocuemnt patameter can get quicky.

```

Thank you so very much!
Would it be at all possible for you to paste the entire macro code here?
I am fairly new to RevitAPI..

[scgq425]

Hi @dwightduronidavy :

 i just add tow row target to create window to get the user input .

do you want to check or debug you code to done this function? 

1. the input window about :

```

string degreeStr = Microsoft.VisualBasic.Interaction.InputBox("input value" , "Rotate","0");

```

2.  Get ActiveDocument

```

  UIDocument uidoc =  Application.ActiveUIDocument;

```

in Revit macro this is vaild . 

just use Appliication can direction get .

Hi @dwightduronidavy 

Kindly follow below steps.

1. Add Microsoft.VisualBasic reference to the project
   
2. Call Input Box Method and pass the parameters.

// Prompt the user for the rotation angle
string angleInput = Microsoft.VisualBasic.Interaction.InputBox("Enter the angle (in degrees) to rotate the model:","Rotate Model File About Internal Origin","0");​

Complete Code for Reference (Errors Resolved)

        public void RotateModelFileAboutIO()	
		{
			UIDocument uidoc = this.Application.ActiveUIDocument;
			Document doc = uidoc.Document;
			
			// Prompt the user for the rotation angle
			string angleInput = Microsoft.VisualBasic.Interaction.InputBox("Enter the angle (in degrees) to rotate the model:", "Rotate Model File About Internal Origin", "0");
			
			double rotationAngleDegrees;
			
			if (!double.TryParse(angleInput, out rotationAngleDegrees))
			{
					TaskDialog.Show("Error", "Invalid angle entered. Please enter a numeric value.");
					return;
			}
			
			// Convert the rotation angle to radians
			double rotationAngle = rotationAngleDegrees * (Math.PI / 180.0);

			// Get the internal origin point as the center of rotation
			XYZ centerPoint = XYZ.Zero;
			
			// Define the rotation axis (Z-axis)
			Line rotationAxis = Line.CreateBound(centerPoint, centerPoint + XYZ.BasisZ);

			// Collect all elements that can be transformed

				// Skip certain elements that are not transformable (e.g., levels, views, phases, grids)
				if (!(element is Level) && !(element is View) && !(element is Phase) && !(element is Grid))

Thank you so much Mohamed. I followed your instructions (imported the VB ref) - but got the following error after executing the code:


After adding the two missing '}', i received the following error:

Hi @dwightduronidavy 

It seems mismatching reference kindly replace code snippet at below the method.

Snippet-01

UIApplication uiapp= new UIApplication(this.Application.Application);
UIDocument uiDoc=uiapp.ActiveUIDocument;
Document doc = uidoc.Document;

Hope this will helps 🙂
