I have to say I officially hate Crystal, sorry. But I have to use it. I'll try to tell you what I have done, and hopefully this will get you started in the right direction.
First I created an XSD by clicking on the project in question --> Add New Item --> XML Schema. Open the schema in the designer and put in the fields and their data types for the data as you want to see it on the report. You can add elements and such by right-clicking in the schema window.
After you are done with that, right-click in the schema window and select Generate Dataset. If you were to click your "Show All Files" button on your project, you would notice that you now have a new .cs file underneath your xsd schema. This is known as a "strongly-typed dataset", if I'm not mistaken.
Now, Crystal is ready to accept your information. The next step is designing the Crystal report itself. Add New Item --> Crystal Report, and you get a report file .rpt. If you right-click in the Field Explorer (on the left hand side) [and probably this is available somewhere in the menu system], you need to find Add/Remove Database. You should see a list of potential data sources, and you should see your strongly-typed dataset here.
I won't walk you through designing a report [edit]although happy to give help if requested[/edit]...
Next step is displaying the report. Create a new blank Windows Form in your project, and drag a CrystalReportViewer component on to the form, and dock it using Fill. [BTW, You probably need to be referencing "CrystalDecisions.CrystalReports.Engine", "CrystalDecisions.ReportSource", "CrystalDecisions.Shared", and "CrystalDecisions.Windows.Forms" in your project]. If you don't see a CrystalReportViewer component anywhere in your toolbox, right-click your toolbox, choose add/remove items, and scroll to CrystalReportViewer.
Finally, to actually pass the information and show the form, you need some or all of the following code:
dsMyTypedDataSet reportSource = new dsMyTypedDataSet ();
reportSource.ReadXml(myFileName);
.
rptMyReportClass rpt = new rptMyReportClass();
rpt.SetDataSource(reportSource);
.
rpt.SetParameterValue("MyParam", myValue);
.
frmReportViewer mdiReportViewer = new frmReportViewer();
.
crystalReportViewer1.ReportSource = rpt; .
.....
.
mdiReportViewer.Show();
.
crystalReportViewer1.ShowLastPage();
NumPages = crystalReportViewer1.GetCurrentPageNumber();
crystalReportViewer1.ShowFirstPage();
this.Text += String.Format(" : {0} Page{1}", NumPages, NumPages == 1 ? "" : "s");
This last bit was what I do to retrieve the number of pages and display it, else it doesn't know how many pages you have.
This is not perfect I'm sure, but please try it out and let me know what doesn't work so I can help you fill in the details.

Hi Susan!
Don’t worry darling! You are not the only one that hates this tedious, incomprehensible, infernal reporting tool! But, alas, here we are using it! I much prefer using SQL reporting, but not all of our clients can afford something that spectacular!
Thank you for replying to my post! I am sure to give your suggestion a try and I promise to keep you posted! I am currently using VCpp 6.0 for development at work, and the only time I have playing around with C# is in my private time! So… it might take me a little while to get back to you!
(On the side lines, are you from SA by any chance? Because I had this rather pleasant
instructor a while back (2002…2003? I think…) and I thought of trying to contact her and perhaps have a little something to drink!)
Thanks again
Willem Le Roux

Take your time, I hope the code sample, although a little rambling, will be of help. I saw that it was formatted really strangely, so I edited it, just for formatting.

No, but thanks for asking! I'll have a drink with you anyway! Oh, wait...I don't drink...drat.

Thanks for your help Susan!
I read your "edited" version and I will be playing around with Crystal tonight and again on Thursday! Like I said, I will keep you posted on how I do!
I will pop you some mail when I am in the states again... which might only be in 4-5years or so! I have a friend that stays in California somewhere! Then I will pay my dues in the form of a cup of hot chocolate and a muffin! (Or something along those lines)
Thanks again Susan!

Hi all,
Can anybody tell me how to get my motherboards serial number?
Any help would be great!
Willem Le Roux

You can use WMI and the System.Managemnet namespace to get the serial number, IF AND ONLY IF your motherboard manufacturer supplies the WMI Management components to expose this information. Most don't. Check with your motherboard manufacturer for some kind of Management application that might install the required WMI classes.

Hi Dave!
Thanks for your reply and I will surly give this a shot, but I am looking for something a little more... pertinent shall I say...
I want to get the registration key of motherboards of various types, ages, makes ECT. ECT. ECT. It is going to be WAY too much effort trying to explain this "Installation of WMI Management components" scenario to every user!
Perhaps there is an easier way to go about this scenario? Perhaps a MAC address or something to this avail. If you can be of ANY assistance, please let me know!
Kind greetings
Willem

WMI is the only way you're going to do this. And, still, that's IF the motherboard manufacturer supplies it.
There's no standard method to get this and no "registration key" for motherboards. There's various components that make up a motherboard that are scattered throughout the device manager though. That's accessible through the Setup API functions. There's no .NET class that wraps it. How useful that information is depends on what you mean by "registration key" and what you want to do with it.

Hey sorry Dave!
Little typo! My brain was clearly broken that day! Work overload! I mean the "serial number" of the motherboard. Or the serial number for any component that is standard on any motherboard for that matter! Or a MAC address... Anything on the motherboard that is standard and unique! I will have a look through the device manager and toy around a bit!
Once again, sorry for my little typo! "Registration key" of the motherboard! That is stupid!
Thanks for your effort Dave! Really appreciate it! Will keep you posted!
Cheers!
Willem

Again, there is no standard that says a manufacturer has to supply this information on a motherboard, or any component on it. The only "standard" access method is WMI. There is no API call you can make to get this information other than WMI.
On top of that, it appears that only system manufacturers, like Dell and HP, even supply this information at all. The serial number belongs to the entire system, not the motherboard.
Basically, what you want cannot be found on every notherboard. If you're looking for something to build a registration key with, this ain't it.

No, there isn't. What are you trying to do accomplish with this?

Hi Friends
How can i generate standard Deviation graph? I have calculate mean and standard Deviation according to Array of values but How can i Plot Graph??
|
|
|
|
|
|
I am developing own library for Graph so plz give me any idea or sample code.
|
|
|
|
|
I never worked with GDI+ myself.
To get an example take a look at the source code of the library i suggested or explore the documentation of the System.Drawing namespace especially of the Graphics class.

I beleive a standard deviation graph can be done with just lines. There is a quick-and-dirty way to do this, by overriding the Paint event of a PictureBox and drawing on the pictures Graphics object. But, depending on how frequently the graph gets updated or the screen gets redrawn, you can see flicker when the pic is redrawn.
You could create a full custom control, with properties to accept an array of data, and custom drawing done in the OnPaint protected method. The actual logic for drawing the graph will completely depend on how you represent, store, and pass in the data being graphed, so I can't give you much example code there.
Just create a new Custom Control in your project, and override the OnPaint method (inherited from the System.Windows.Forms.Control class).

int a = 1.76543
how to i print out in such it way it'll only display 1.76?
|
|
|
|
|
If you're sure you'll always get d.dddd, you can simply multiply it by 100 (or the number of digits you want after the decimal point, cast it to an int and divide back by 100. Something like
double a = 1.76543;
int x = ((int)(a * 100)))/ 100.00;
Regards
Senthil

a.ToString("0.00") should do the job.
For some more information on formatting of numeric strings take a look at this page[^].

double a = 1.76543;

Hi,
I have a little (very small) app that use too much memory, how can i release resources that are not in use (loaded dll's that are no more necesary for example and all type of garbage that can be disposed) whithout closing my app of course?
When i load a dll can i unload it when it's not needed and my app is in idle?
I saw in a post a few days ago (and can't find it again) an instruction to unload resources when the app is close, if some one can provide me that line of code, this is for making sure i release resources.
Thanx.
