crystal reports changing text field value on runtime

[clahl]

hi group,

i have a problem that didn't show up on any sample files or in two books i bought (crystal reports for dummies and wrox - professional crystal reports for vs.net).

my users can specify the date range of the report on a web-form by filling start and end date into two textboxes before the dataset behind the report is filled.

in no example to reports ever show the exact date range selected in the report header. it's always like '... 2001' but what if users specified 10/23/02 to 11/15/02? how do i show the selected dates in the report header?

thanks if anyone can help me with it.

You can use the Format() function to specify the format.

hi wizbang,

probably i didn't point it out clear enough, i'd be happy if it was a problem with formating or i don't get your hint.

i have a web-form with two text-boxes for date entries (beginn and end date), two drop down lists (one for choosing the report) and two buttons (one for producing the crystal report as pdf and sending it to the browser, the other for sending the report to the report viewer on the web form). all of this works fine.

the problem is that in the produced report i need the beginn and end dates specified in the two text boxes before producing the report. the two dates from the boxes are used for specifying data fed into a dataset by altering the underlying sql statement. the dataset content that is pushed into the report. because users who see the report need to excactly know what period the report covers, the begin and end date from the sql-statement should be quoted in the report header.

to be honest for the beginnen i don't care in which format the dates show up as long as they do.


any ideas?

It seems as if yours is a matter of passing parameters to Crystal Report.
If this is the case, then look at what Babu, iamgautham and dinesh123 wrote:

There is a formula editor in the Crystal report where u can build the formula.
U can pass the formula from the code to Crystal report SelectionFormula parameter.
Eg:
CrystalReport1.SelectionFormula =" {dept.EMPLOYEE ID} = {employee.EMPLOYEE ID}"
U can get more help from the Cystal report help.

using automation server(cpeaut32.dll)
after creating application, report objects etc..

Private mobjcrpParam As CRPEAuto.ParameterFieldDefinition
Private mobjcrpParams As CRPEAuto.ParameterFieldDefinitions

Set mobjcrpParams = mobjcrpRep.ParameterFields
'' where mobjcrpRep is the report object
mobjcrpRep.ParameterPromptingEnabled = False
'' to prompt the parameter window or not
Set mobjcrpParam = mobjcrpParams.Item(1)

Dim paramValue As String
paramValue ="HELLO"
mobjcrpParam.SetCurrentValue paramValue

Re: Crystal Report
hi,
That formulas(0) value is incorrect.
First, you have to create formula in crystal report design time.
assume "myVar" is your formula variable
Then you pass the value to that variable like
CrptHistory.Formulas(0) = "myVar = 'Hello'"

yours,
Babu

Re: Many Problems in Crystal Reports
hi,
for example you want to print name = 'Raj'
' you should enter the single quote for string data type
cr.SelectionFormula = "{Employee.Name} = 'Raj'"
'you no need to enter single quote for numeric data type.
cr.SelectionFormula = "{Employee.RecNo} = 10001"

do your level best.

' Section5 is the Section number of the Report Header
Set scSection = crReportDesigner.Sections("Section5")
addTitle scSection, strTitle

'Procedure for adding titles in the crystal reports

hi Ramagnanavel,

from the way it looks i have the feeling you understood what my problem is. so i tried to do the same in my program, but there remain unsolved issues.

the namespaces i have are the following:
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Imports System.Data.OleDb
Imports System.Data

after i copied your code samples, i do get error messages from the following parts:

Dim scSection As CRAXDRT.Section

what is craxdrt? i didn't find entires abou it in the help files

i found some things about it on the web. didn't it install with my vs.net enterprise architect standard installation? i had my harddisk searched for craxdrt9.dll and didn't get any results.

so next i try to find our what craxdrt9.dll is. things are just never that easy are they? who thought that transferring a string into a cr would be that complicated? i didnt.

thanks for your help

You're not using Crystal Report with Vb6.0. You're using it with DotNet...
If this is the case, I think I should move your post to an appropriate forum (Vb.Net forum)...

hi group,

i moved the thread from another vb forum where i posted it by accident.

i'm looking for a way to transfer a string into the report header of a crystal report. i'm working with vb.net enterprise architect standard installation (with other lanugages not installed).

just learned that there is something called craxdrt9.dll to be installed. is this only for vb6 or also for .net? i couldn't find it on my harddrive.

any help appreciated a lot, bought two books but it was never mentioned.
