Error 2015 Evaluate

formulas as strings and have Excel VBA compute them for you. Only recently I discovered that some of the cells in a workbook error 2015 vba contained #VALUE? instead of a sound value. After some investigation I found
Vba Error 2015 Vlookup
out that, without raising any error at application level (in VBA), the Application.Evaluate function failed consistently with this excel error 2015 evaluate error whenever a particular condition occurred. This condition is related to limits in the underlying software layer of Excel, the one that runs Application.Evaluate. Apparently this particular error occurs
Excel Vba Error 2029
when the parsed function returns a string value having a length above 255 characters. As long as the length of the string is less than or equal to 255 characters, the return value is the desired string. Above 255 characters, the function "crashes". In my case, I was not immediately attended on this error because I used a application.evaluate vba Variant to store the returned value from Application.Evaluate (sample code): Dim vValue As Variant vValue = Application.Evaluate("GetData()") ' Error 2015 saved in vValue if GetData returns 255+ characters ActiveCell.Value = vValue If I would have used a String to store the value, I would probably have gotten a "Runtime Error 13 - Type Mismatch" with Excel booming out of my routine without any debugging possibility (sample code): Dim sValue As String sValue = Application.Evaluate("GetData()") ' Run-time error if GetData() returns 255+ characters ActiveCell.Value = sValue To catch problems, I now completed code with an If statement (sample code): Dim vValue As Variant vValue = Application.Evaluate("GetData()") If (VBA.VarType(vValue) = vbError) Then ActiveCell.Value = "String Overflow on GetData()" Else ActiveCell.Value = vValue End If There seem to be more Excel functions that suffer from this 255 character limit, but could not establish which. For the moment, I will apply some workarounds until it gets solved by Microsoft. Dutch Like this:Like Loading... Related Comments (3) 3 Comments » Thanks for this, I was passing through a #valu

To do this I have the calculation in Excel set to manual and I am comparing the current value of the DBRW formula with the value contained withing the formula's error 2015 cell. I am using Excel 2003.I have one specific DBRW that In the cell works every time - returning a decimal number. I am then using VBA to evaulate this formula by using the 'Application.Evaluate' function - in order to compare the result of the DBRW with the cell value.Every time I do this I reveive an 'Error 2015' or 'Type mismatch' error.I am returning the result into a variant object - error 2015 evaluate so there can be no 'type mismatch' on the part of the variable I am loading the result of the 'Evaluate' into.I have tried restarting Excel (in case this is some kind of 'Caching' issue) to no effect.I am aware of the issue with 'Evaluate' where one or more parameters has 255 or more characters or the result of the function is a string in excess of 255 characters. However I know this is not the case in this instance.http://dutchgemini.wordpress.com/2009/08/07/error-2015-using-application-evaluate-in-excel-vba/I had the VBA stop before the 'Evaluate' is executed and evaluated each parameter seperatly by hand - none return an error and each is a valid and correct parameter value for the DBRW. This is not supprising since in the worksheet the cell formula evaulates without an error every time. However if I print the formula text to the debug window and then, with the code paused, manually execute the 'Evaluate' this fails with the same messsage.One thought I did have is that two of the parameters / dimension elements resolve to what can loosely be refrered to as dates i.e. one is a month 'MAR' and one is a year '2012'. I have seen a MS article where Evaluate functions that include dates can be an issue but it does not a
