I've a form and a Report. The report takes the datas in my db.mdb file. I have'nt got any problem of this situation. but I have to do another thing in my program. The topic of my report must be changeable. User can type a text in a textbox of my form and this text user typed must be written in my report as a topic. how can I do that ? Please help me somebody, and I'm so sorry for my English
dont cry , dont cry . Please, please , please 
.Your english is fine
Taake a parameter in Crystal Reports and set its value in Form.
ReportObject.SetParameterValue("ParameterName",Value);
use this formual, this will set your topic at runtime.Take the value from textbox on your form where user enters the topic.
In fact I managed your comment. but my program wants to enter the text from user when the report loading Actually I dont like that. I want that the user can enter his/her own text in a textbox in my form. and when he/she click a button, my report can appear, and doesn't ask another question. If you know how can I do that, please please please help me
Also it seems you are getting a parameter window, there is another post around somewhere which tells how to supress parameter window.
thanks your answer. I did that you have told. But my .net2005 shows an error when the program running. my parameter textbox's name is : mytopictxt and my codes like that ;
Dim myreport As New MyCrystalReport1myreport.SetParameterValue(
"mytopic", topictxt)CrystalReportViewer1.ReportSource = myreport
topictxt is a variable that defined in a module as a public. As I told you, I have another form in my program. This form has a textbox that name is mytopicbox.
when a button clicks, my another form that includes a CrystalReportWiever appears.
What should I do? where should myreport.SetPa....bla bla code be written? in my form that includes textbox, or another form includes CrystalReportWiever1 ?
It should be written on form where you are creating object of your report
this code seems to be OK
Dim myreport As New MyCrystalReport1
myreport.SetParameterValue("mytopic",topictxt)
CrystalReportViewer1.ReportSource = myreport
"mytopic" - This should be parameter in your report ok.
pass value of textbox on first form to this variable "topictxt"
when you call your report , also pass value of TextBox from first form to second form so that value gets assigned to variable "topictxt"
thank you very very much. you are one of the good guys I have ever seen. I managed it owing to you. thank you again thank you............
