You need to create a strongly typed DataSet in your project, one that represents the data schema from the stored procedure.
Then you need to base your report off the strongly typed DataSet.
Then just assign the DataSource property of the CrystalReport to the instance of the DataSet returned from your your stored procedure.
If at first you don't succeed ... post it on The Code Project and Pray.

i am on a windows project and i applied backgroundimage to all the forms earlier. And now when i want to apply another new background image to a form then , i can see the new image as background image to a form in visual studio but at the runtime no image is displayed, and the form is displayed with background color but not with the image. After that through code also i tried using imagelist . Then indexoutofrange exception is coming.

hi everybody
i made a program which works in system tray when i minimize it
everything is ok till here
but when i made its exe it gives error and doesnt open the exe windows form
it is error because of the icon that i have choosen for the notifyicon
it cant find the source file when i run the exe
i tried to add an icon file to the program to manage it
but it gives the same error
it works when i dont choose any icon for notifyicon
so how i can manage to choose an icon for notifyicon
i will be happy if u help me
|

Assuming the file you are using is a valid icon resource, add the file to the project's resources
Project | YourProjectProperties then the Resources tab on the left.
Set the Icon for the NotifyIcon in code
notifyIcon.Icon = Properties.Resources.youricon
The only time I've had an issue with this was trying to use 'vista' icons. IIRC, the 256x256 caused problems, but that's not needed for a tray icon anyway!

thanks for the reply
i think i did it because i dont get an error when i run it
but now i have a new problem
when i try to make its .exe i got an error which says
form1.cs <23,32> : the name 'Properties' doesnt exist in the current context
i use Visual Studio's own Comand prompt to make it .exe
i think i should add one more file to debug
but which one i dont know

0. Use the <pre></pre> to make your code pretty, see:

1. Why are you re-populating on the SelectedIndexChanged event? Populate the picklist ONCE when you load the control.

My work here is done.

While you are adding items inside foreach loop then you don't need to set datasource to dropdownlist.
string connection1 = ConfigurationManager.AppSettings["conn"];<br />
OleDbConnection con1 = new OleDbConnection(connection1);<br />
con1.Open();<br />
<br />
<br />
OleDbDataReader dr;<br />
<br />
string query = "select DISTINCT DEPARTMENT from TIME_DETAILS ";<br />
OleDbDataAdapter da1 = new OleDbDataAdapter(query,con1);<br />
DataSet ds1 = new DataSet();<br />
OleDbCommand cmd = new OleDbCommand(query,con1);<br />
da1.SelectCommand=cmd;<br />
da1.Fill(ds1,"dept");<br />
DataTable dep=ds1.Tables["dept"];<br />
dr = cmd.ExecuteReader();<br />
<br />
if(dep.Rows.Count>0)<br />
{<br />
foreach (DataRow row in dep.Rows )<br />
{<br />
DropDownList2.Items.Add(new ListItem(row[0].ToString(),row[0].ToString()));<br />
}<br />
<br />
}

try this:
DropDownList2.DataSource = ds1.Tables["dept"];
DropDownList2.DataTextField = "DEPARTMENT";//the col which you want to display
DropDownList2.DataValueField = "";//DEPARTMENT id or anything else
DropDownList2.DataBind();

I have windows app and am using c#. I want to launch default browser from c# program and pass some parameters. Basically what i have is content type (eg. "application/msword") and byte array of content (word/excel/pdf docs in byte array). I want to pass these two parameters to browser and let it open the doc. Can anybody please guide me to achieve this? One more thing i don't want to create any file in local disk.
Thanks.

Are you saying the document is not on your disk or some remote machine, but in memory? If yes, simply save it to a temporary location and display it from there. That is what even browsers do.
Once you've saved it, try Process.Start("URL of your document"). That will open the default handler (generally, MS Word) though. Launching a local .DOC file with your default browser might be slightly more complicated, and I'm not even sure why you'd want to do that.
Cheers,
Vikram. (Proud to have finally cracked a CCC!)

Thanks Vikram, here are my problems:
1. I actually don't want to store doc in local machine and handle creation and deletion of files. If in any case end user have very minimum rights i may not be able to create file even. Here maybe i should think of memory stream?
2. "Launching a local .DOC file with your default browser might be slightly more complicated, and I'm not even sure why you'd want to do that. " i din't get this? Are you suggesting to launch directly ms word, excel or acrobat softwares and display docs in them instead of using browser? if yes, the problem with this approach is i need to know and code for all types of docs, if i use browser i no need to bother about this as far as i supply content type and byte array.
Thanks.

AFAIK, *every* user will have read + write access to a temp directory. Path.GetTempPath() is your friend. I doubt Word can handle in-memory files.

Yes, that's what I suggest and it's the cleanest and the easiest. You don't have to handle any extra types, Process.Start("yourfile") will open it with the default program. It's opening with the default browser that is dubious.

Hey..

i have a form. i want to so an effect that when user try to move it will move and tyhe opacity will become 30%.when the user leave the form the opacity of the form will become 100%.Just Like - when an exception occures in Visual Studio and a message form comes in front what can be move by mouse and reduces the opacity.
can anyone give the solution. Should i use "Event Move()"?
code segment will help me a lot.
Thanks .

Hi,
I"m currently designing reports for my company (yeah ) and I'm trying to define my datasets using xsd files in VS 2008 design time. I'm creating table adapters and providing the select queries which in turn populates my tables. I need to know if there is a way for me to pass parameters to the queries that I use in those table adapters without having to resort to runtime code (In other words in design-time in the form of a placeholder of some sort) and at a later stage pass that parameter from another class instance.
In code you would do:
SqlCommand Cmd = ....;
SqlParameter par1 = new SqlParameter();
...//Set all the parameter properties
Cmd.Parameters.Add(par1);
I'll consider runtime code if it happens in the dataset's code behind file. My reporting solution (XtraReports) works quite well with xsd datasets and designing a report mostly in design time is far less time consuming than doing all the databinding in the code behind. Can anybody plz help?
Regards
Jacobus

da1.Fill(ds1,"group");
DataTable dt1 = ds1.Tables["group"];
da1 is a data adapter and ds1 is dataset.I wrote a code for binding to dropdownlist and it is working fine.I saw a code demo,dat's why i gave that "group" parameter.But i cannot understand it's use...n also it is not again used anywhere else in the code...What is that parameter actually?

Object browser would have told you that. Anyways, that is the name of the table in the dataset. You can refer to a table in the dataset through the index or by the name.
It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

i assumed that,that it should be the name of the table in the dataset.....But we are again creating a datatable dt1..are we assigning the value of the datatable,group,to dt1?And if i want to create one more table,patient,in teh same dataset will
da1.Fill(ds1,"patients");
DataTable dt2 = ds1.Tables["patients"];work?????????

Hi,
first of all: Don't cross post.
As already mentioned in the ASP.NET forum you have to use brackets in the correct way:
INSERT INTO Registration [DATE OF BIRTH], [CONTACT NUMBER] VALUES (...
Did you really use coulmn names with whitespace within your db? You should either use camelcase or underscore to seperate the words. And pay attention to sql injection (within your values). Search google for prepared statements.
