View 2 RepliesI have a vb6 app that creates an Excel 2003 doc that I need to export to pdf. I have the following code to export,
excelWorkBook.Worksheets.PrintOut Copies:=1, ActivePrinter:="Adobe PDF",' printtofile:=True, prtofilename:=strOutputName
but nothing prints. The app exports to pdf works in test, but not when I move it to production. I have to remote into the machine that runs the app, so my printers from my local pc are "attched" to the remote session, can this have something to do with no output. The remote machine does not have the Adobe print drivers installed.
What can I do to get the export to work?

I'm developing excel add-ins with VS2008 on Excel 2003/2007 and would like to start supporting Excel 2010. So moving to VS2010 is a must but there is no way to continue developing add-ins for Excel 2003 there. Is there a possibility to work under VS2010 and then use/share the business logic dlls on VS2008 for Excel 2003??

View 2 RepliesWe have a Windows based application whose GUI is in Unicode coding (UTF-16 I believe). But each time I copy a string from a cell of MS Excel 2003 or from Nodepad and paste it to the GUI of our application, the string can not be displayed correctly, just comes out. ( but if you type directly from the keyboard into the GUI, it's fine). I believe it is because the string from Excel or Notepad is one-byte string (maybe UTF-8, I am not sure). What is default encoding in Excel 2003? How can I make it work correctly - change the encoding in Excel or Notepad or some other way?

View 3 Replieshow to create an 'Access-like' input mask for hastening date data entry.
Using C Pearson's much quoted code I've modified it as such:
Private Sub Worksheet_Change(ByVal Target As Excel.Range)
Dim DateStr As String[code]....
Note: I'm aware that most of the time I'm simply re-typing the original code - it was a learning experiencing and I also realised that the different American and Australian date formatting was less of a programming issue due to the systems being set up differently in the first place.My issue is having run tests using only 4 digit entry, all types of digit entry, with and without DateValue on the final DateStr, changing the cell format to text, to general, to date - always results in a code like "8811" (i.e. 08/08/2011) being changed into 01/01/1924 (approximately).
At first I assumed the use of "DateValue" in assigning the final .Formula value was forcing this conversion. However, with or without DateValue it still seems to read the figure as a DateValue and convert it as such.I'm sure it has to be something elemental that I'm missing given the scores of people I alone have seen on boards reading C Pearson's code and not coming up with another peep.
I haven't used VBA in a very very long time. So, go easy on me. I'm trying to do an IF THEN ELSE function where whatever the pVal cell says, Excel will input the correct currency value in the next cell. I have the cell format in the Excel workbook set to currency with 2 decimal places. However, when I add the UDF, it rounds up! I basically copied and pasted this code from an online website, but theirs did not have any decimals. I've tried calcvalue = Format("48.95","Currency") but it still rounds. I'm sure I'm leaving out something simple. Here's my function formula so far.

I have an executable built with VB2005 which is used to launch a password protected excel workbook, and the exe is used to hide the password then run some macros to setup menu commands and protect the workbook so that it can't be altered by the users.
The exe was built by registering the 11.0 version of Microsoft.Office.Interp.Excel in the project, and builds successfully. I can launch the spreadsheet sucessfully on my own desktop using Office 2003 and have tested everything on another 2 other independent desktops using Office 2003 however when I make it available for wider use, I have received a lot of feedback that excel will simply not launch when the exe is run. I had a look at one of the desktops where Excel wouldn't run and there were no associated entries in the Windows Event Viewer that I could see.
It seems that there are no problems running the exe using Office 2007.
My development machine was recently re-imaged with Office 2007 and I re-installed Office 2003, and re-registered the Excel PIA to allow it to work with Excel 2003. NOt sure if this could be hangover of having originally built the exe with Office 2007 then reverting of '2003.
Apologies if this is fairly basic stuff but I'm at a bit of a loss what to look for to identify why the exe will sucessfully launch Excel on some PCs but not others using the same operating system and version of Excel.

I need to be able to test if the current view is print preview in Excel 2003.
Is there something in the excel object model to simply access this property? (Like the application.printpreview in the Word object model...).
PS: Long story short, I'm developing a vsto addin with keyboard short-cuts to my custom functions, and I need to disable this shortcuts when print preview is on.
