I want to use the DateTimePicker(s) to control the date ranges in my selection criteria, but I'm having trouble getting the right format.
The DateTimePicker.Text (or .Value) is giving me the date in "mm/dd/yyyy" format, but my "vCNDBReport.CrystalReportViewer1.SelectionFormula" seems to only retrieve records when I pass it a date in "yyyy,mm,dd" format.
What am I doing wrong?
My database is Oracle. I hope doesn't make a difference, but if it does, is there a reasonable way to get (convert to) the expected date format?
Any help would be truely appreciated.

Change the selection formula to use the CDate() function. This converts a string to the Date data type.

Hi Brian,
I tried your suggestion in the code shown below and still ended up with an "mm/dd/yyyy" format in my selection string. Am I using it in the wrong place? I have several parameters to concatenate as part of the selection argument.
==============
If cboNamedDateRange.Text = "" Then
gFromDate = CDate(DateTimePicker1.Text)gToDate = CDate(DateTimePicker2.Text)gSelDateRange = "{SW_CASE.SWDATECREATED} in Date(" & gFromDate & ") to Date (" & gToDate & ") and " ElsegSelDateRange = "{SW_CASE.SWDATECREATED} in " & cboNamedDateRange.Text & " and " End IfSelect_String = gSelDateRange Select_String = Select_String & "{BRX_CONTACT.BRXSECURITY} = 'US' and {SW_CUSTOMER.SWREGION} = '120 '" vCNDBReport.CrystalReportViewer1.SelectionFormula = Select_String =======
Thanks and Regards, ------------- -jrw |

Why aren't you using Date() for the cboName... dropdown?. Plus, I think you need to put quotes around the data string within the actual selection formula. You have to act like you were typing the data formula into CR manually. Thus, if you would put quotes around a date string when typing it in then you would do the same when building the selection string with code.

The cboNamedDateRange contains a "Collection" of Crystal Date Ranges and is used exclusive of the FromDate and ToDate parameters. The values are:
LastFullMonth
LastFullWeek
MonthToDate
YearToDate
LastYearYTD
Calendar1stQtr
Calendar2ndQtr... etc.
and is used in the selection formula as shown here:
gSelDateRange = "{SW_CASE.SWDATECREATED} in YearToDate and "... plus Security and Region Parms
------
When I was initially testing the Report I used a hard-coded selection string:
gSelDateRange = "{SW_CASE.SWDATECREATED} in Date(2006,01,01) to Date (2007,08,07) and "... plus Security and Region Parms
and it worked as coded.
My final solution was to change the Definition of the global date fields (gFromDate, gToDate) from type "Date" to "String" and use the following to create the desired date format:
gFromDate = Format(DateTimePicker1.Value, "yyyy,MM,dd")
gToDate = Format(DateTimePicker2.Value, "yyyy,MM,dd")
Since the two options are mutually exclusive (controlled by Radial buttons) the user is kept from entering in bad dates. They either selecta Named Date Range from the dropdown list or the DateTimePicker prohibits bad date entries. And having to edit for bad dates is kept to a minimum. ------------- -jrw |

WattsJr,
Just recently encountered and overcome a similar problem.
Here's the heart of the problem: In older reports, there was an option to "Convert Dates To String". (Under Report Options in the designer). For some reports I don't see that option, so I think it's probably not available in new version due to the problem it causes.
If the report has it set to convert dates to string, then you have to put in a string representation of a date in the selection formula.
If the report has it set to convert to date, or not set at all, then you have to use the crystal Date() function as BrianB suggested.
Now, this brings up another problem: After loading a report, how do you see this setting for that report?
In C++ you used to have access to this propery in the document object. I imaging you could in VB too. For the life of me, I can't find it in C#. I think they've retired it along with the setting itself in the designer. This was a huge problem for me.
I found a work around. You have to interrogate the type of the date field as such:
if (crDoc.Database.Tables["yourTable"].Fields["yourdateField"].ValueType == CrystalDecisions.Shared.FieldValueType.StringField)
{ ... use the string format ...}
else
{ ... use the date format ...}
What a pain this all was.
Shabbi, have you tried getting the datetime on an earlier pass, such as WhileReadingRecords or BeforeReadingRecords? Just a suggestion.

Shabbi,
Your problem seems to be different from WattsJR's. It should probably be it's own thread. But anyway,
I'm not too familiar with generating a report with java in this way. There's special fields called PrintDate and PrintTime. Yes, you can wrap them in ToText (PrintDate) if you want them to appear in the footer.
For me, it prints the same time on all pages.
When a report is run, it goes through the report in multiple passes. I'm sure this is in the book.
BeforeReadingRecords, and WhileReadingRecords are times when the report engine is processing the report. They happen before WhilePrintingRecords.
See if it'll let you put "BeforeReadingRecords" in the formula on the first line above "ToText(PrintTime)".
