Thank you for explaining! I really appreciate it. I have one more follow-up question regarding the use of 'bool'. I noticed you changed validFacet to a variable within the body of the code rather than the original use as a method pointing back to public static bool ValidFacet. My question is this: How come the error 'not all code paths return a value' is not being thrown for ValidFacet when it is never used in the body of the code? In my attempts to use return type values other than 'void' I keep receiving the 'not all code paths' error message. For example: public static IPoint NewPoint (double X, double y) { //create a new point and put the coordinates provided IPoint pntNew; IPoint newPoint; pntNew = new Point(); pntNew.PutCoords(X, y); //return the new geometry newPoint = pntNew; } I either have the 'code paths' error or if I change newPoint to NewPoint then I receive a method error. The only way to not have an error is to remove IPoint which seems like it will change the function of NewPoint. So, how come your procedure can use 'bool', use validFacet as a variable, not mention ValidFacet in the code body, and not receive an error?

Ted, Thank you for your help. I was not aware of VBA's automatic conversion to variant. It is something I am now trying to make sure I consider as the problem when encountering other errors.

Daniel, Thanks for your help, the code appears to work! I have other code I am working on that are tied-in to that code so I can't currently test it but all the errors are gone and other areas that were also using a ValidFacet reference are no longer showing errors. I am interested in the logic and reasoning behind the changes you made. If you don't mind, I know (and appreciate) that you have already spend quite a bit of time translating the code, I have a few questions about some of your modifications. First, what made you decide to change from 'void' to 'bool'? I have other class programs that use boolean in the code but I have as 'void' in the return type. Second, I noticed you are not using the IFeatureCursor. Why is it no longer needed; ie. what code modifications made IFeatureCursor obsolete? Lastly, why were you able to define pFlayer as null instead of using pFLayer = (IFeatureLayer)pMap.get_Layer(0); . Is it because you upgraded the else if to an if and included in the logic statement else for pSearchLayer = pFlayer and set it to for a non-blank pSearchLayer?

Since the statement seems to be checking to see if the variable's value exists in the ValidFacet, I have also tried if (!FacetClass.ValidFacet.Contains(pTopFac)) The statement does not work but perhaps it is closer to what is needed?

I have encountered another instance where the same situation arises; ValidFacet is used in a different class and with a string parameter. I still cannot figure out exactly what the original vba code is trying to say or how to convert the vba to C#. If Not ValidFacet(pTopFac) Then pTopFac = "END OF DATA" End If So far I have this (which doesn't work): if (FacetClass.ValidFacet() != pTopFac) { pTopFac = "END OF DATA"; }

I am transferring a code from a VBA module to a C# arcmap add-in. I am using ArcMap 10.2 and Visual Studio 2010. I cannot figure out how to translate what appears to be a method from a different class (module) within an ElseIf Not statement that places 2 variables from the current class within the method. The biggest problem for me in translating the code is that I can't really figure out with 100% certainty what the original code is saying with that ElseIf Not statement. Any assistance will be appreciated. This is the code snippet that I am referring to (ValidFacet is the method from a different module): ElseIf Not ValidFacet(txtFacetNumber.Text & cboFacetLetter.Text) Then MsgBox "The facet you entered does not exist." & vbCrLf & _ "Please check and try again.", vbSystemModal Here it is again within the original VBA code. Private Sub cmdCreateFacet_Click() Dim strFacetNumber As String If txtFacetNumber.Text = "" Then MsgBox "You must inter a value for the facet.", vbCritical + vbSystemModal txtFacetNumber.SetFocus Exit Sub ElseIf cboFacetLetter.Text = "" And Not optFullFacet.Value Then MsgBox "You must inter a value for the facet letter.", vbCritical + vbSystemModal cboFacetLetter.SetFocus Exit Sub ElseIf Not ValidFacet(txtFacetNumber.Text & cboFacetLetter.Text) Then MsgBox "The facet you entered does not exist." & vbCrLf & _ "Please check and try again.", vbSystemModal cboFacetLetter.Text = "" With txtFacetNumber .Text = "" .SetFocus End With Exit Sub End If strFacetNumber = txtFacetNumber.Text & cboFacetLetter.Text DrawMap strFacetNumber 'MsgBox "Drawing" cmdExit_Click End Sub Here is my C# translation so far. I have created a different class (FacetClass) for the ValidFacet method. I reference the FacetClass namespace (SingleFacet1) within the 'using' section although both SingleFacetForm1 and FacetClass are from the same namespace. public partial class SingleFacetForm1 : Form { private void searchBtn_Click(object sender, EventArgs e) { string facetNumberstr; if (facetNumbertxt.Text == "") { MessageBox.Show(new Form {TopMost = true }, "You must enter a value for the facet."); facetNumbertxt.Focus(); } else if (qFacetCmb.Text == "" && !(wFacetrb.Checked)) { MessageBox.Show(new Form {TopMost = true }, "You must enter a value for the facet letter."); qFacetCmb.Focus(); } else (! FacetClass.ValidFacet(facetNumbertxt.Text && qFacetCmb.Text)) { MessageBox.Show(new Form {TopMost = true }, "The facet you entered does not exist." + newLine + " " + "Please check and try again."); qFacetCmb.Text = ""; facetNumbertxt.Text = ""; facetNumbertxt.Focus(); } facetNumberstr = facetNumbertxt.Text + qFacetCmb.Text; facetNumberstr.DrawMap facetNumberstr; //facetNumberstr = new Draw(Map); //Draw(Map) (facetNumberstr); MessageBox.Show("Drawing"); //cancelBtn_Click(); cancelBtn_Click } And just in case it helps, here is my C# code for ValidFacet: public static void ValidFacet() { string newLine = System.Environment.NewLine; IMxDocument pMxDoc = ArcMap.Document; IMap pMap = pMxDoc.FocusMap; IFeatureLayer pFLayer; bool ValidFacet = true; string facetStr = ""; int y; pFLayer = (IFeatureLayer)pMap.get_Layer(0); for (y = 0; y <= pMap.LayerCount - 1; y++) { if (pMap.get_Layer(y).Name == "Facet") { pFLayer = pMap.get_Layer(y) as IFeatureLayer; } else if (pFLayer as IFeatureLayer == null) { MessageBox.Show("Failed to find the Facet Layer." + newLine + "Please check and try again"); ValidFacet = false; } } //IFeatureLayer pFLayer; IGeoFeatureLayer pSearchLayer; IFeatureClass pSearchFC; IFeatureCursor pFCursor; IQueryFilter pQueryFilter; //pFLayer = pSearchLayer; pSearchLayer = (IGeoFeatureLayer)pFLayer; pSearchFC = pSearchLayer.DisplayFeatureClass; //Set queryfilter and search for pages to update pQueryFilter = new QueryFilter(); String strSelField = "qfname"; pQueryFilter.WhereClause = strSelField + " like '" + facetStr + "%'"; pFCursor = pSearchFC.Search(pQueryFilter, false); if (pSearchFC.FeatureCount(pQueryFilter) < 1) { ValidFacet = false; } }

So drag a (Select Elements) rectangle over the area, delete the rectangle and the green lines (which were selected behind the scenes) will also be deleted? I will have to give this a try the next time it happens. Thanks.

I don't know about what happens in Maegan's case, but for me, I can't ever select the green lines. I have tried to Identify the lines but the few times I get a result, the result does not make any sense.

This has happened to me. In my case the map would look fine when I closed it but then when I reopened it or modified the layout, the green lines would appear. Always two of them. I have managed to create a (4th) version of my map that the green lines have yet to appear in. I took everything off the page layout (ie. scale bar, compass, text, border). Then, using the select tool, I drew a selection area over the entire map. When I did that, I discovered two little-bitty blank boxes at the bottom right of my page. I deleted those two boxes and re-inserted everything from scratch. I don't know for certain that the boxes were causing the problem but the lines have not re-appeared so perhaps it is worth a try for you.

ESRI has a Spatial Analyst tutorial: http://help.arcgis.com/en/arcgisdesktop/10.0/pdf/spatial-analyst-tutorial.pdf Colorado State University has a paper that includes a brief description of spatial analysis http://www.consplan.com/images/figures29.pdf To understand the different types of spatial analyses available, you can look at ESRI's complete listing of Spatial Analyst tools ArcGIS Help 10.1

As an extension to what Rebecca and Tim said, it could also be that the browser you are using cannot be used with Geoforms. If adjusting the privacy settings does not work then, if you have not already, try a different browser.

I have been trying to get my print pagelayout working by using the IExportPDF interface. Using that method, I can theoretically specify the boundaries and page extent so that my printed pagelayout is centered on the page. The VBA version of the code worked perfectly with everything centered and looking good. If you are interested in fiddling with my code and getting it to work for your purposes, you can find it here Export Page Layout to PDF using ESRI add-in with vb.net . If you do a search for ExportPDF here or at StackExchange GIS then you can find some different examples of codes using the interface. You can also export to different extensions such as jpg using IExport.

Are you also deleting the file from the location that it is automatically placed in by ArcMap? Ex. On my computer the style is automatically saved in AppData\Roaming\ESRI\Desktop10.2\ArcMap.

I have had this happen too. As in your case, it was not every time. I never noticed anything I did or didn't do differently than normal when the problem occurred. I assumed it was just a glitch and circumvented it by repeating the process 1-2 times. Similar to when I make a selection in a layer, export it to a new layer, open the new layer, double-check it looked okay, go to properties and symbolize, go back to the attribute table and discover all records from the original layer were present.
