I want to create a program that will make it easy for the user to fill in the forms without a Database, NO DATABASE IS NEEDED!!!!! WTF | :WTF:

1. I want to have a form with some Text Boxes or other elements.
2. When the user presses the submit button all of the field data will be sent to a CR (Crystal Report) and then printed in a premade shape and order.

NO DATABASE!!!!!!

It does not need any database, I just want to send the data to CR and print it, How should I do that?????????

I searched many forums but they say just create a db and so on, but I do not want any db.

Please Help me Please!!! Frown | :(

You do not need to create Database you need only DataSet.

Here is what I got from Google with 3 minute of search

Really thanks for your great answer.

But unfortunately, the webpage you gave me does not load here and I cannot find it, but I will try it.

Again: Thanks a million.

Hi.
You should add some Paramter to your Report File(Crystal Report)at design time.
Then you can access it in your Code.Like this:

crystalReport1.Parameter_Name.CurrentValues.AddValue("Ali");
crystalReport1.Parameter_Last_Name.CurrentValues.AddValue("Jalali");
//
Then show your report viewer.

Good luck.

I used to access that way, but I found mayor disadvantage. This approach is good if it is meant to put data that does not include Table like display.

Is there any way ?

Yup, enumerate the EventLogEntry's and check out the UserName[^] property in there.

A quick remark, copied from MSDN:
This property is often blank for events in logs other than the Security log.

Good luck

Form With Shadow

I have a form and a png image file (with a transparent shadow in its border) and what I want is to make a drop shadow effect on the form. I know there are CS_DROPSHADOW solution for this, but I think it doesn't look too good. So I create a "fake" form using CreateWindowEx (via DllImport), and draw the png image file into the fake form.

void CreateFakeForm()
{
            WNDCLASSEX wndClsEx = new WNDCLASSEX();
            wndClsEx.Init();
            wndClsEx.style = CS_VREDRAW | CS_HREDRAW;
            wndClsEx.lpfnWndProc = m_DefWndProcDelegate;
            wndClsEx.cbClsExtra = 0;
            wndClsEx.cbWndExtra = 0;
            wndClsEx.hInstance = GetModuleHandle(null);
            wndClsEx.hIcon = IntPtr.Zero;
            wndClsEx.hIconSm = IntPtr.Zero;
            wndClsEx.hCursor = IntPtr.Zero;
            wndClsEx.hbrBackground = IntPtr.Zero;
            wndClsEx.lpszClassName = m_WndClsName;
            wndClsEx.lpszMenuName = null;

            bool success = RegisterClassEx(ref wndClsEx) != 0;

            UInt32 dwExStyle = WS_EX_LAYERED |
                WS_EX_TRANSPARENT |
                WS_EX_NOACTIVATE |
                WS_EX_LEFT;
            UInt32 dwStyle = WS_VISIBLE | WS_OVERLAPPED;
            
            FakeWndHandle = CreateWindowEx(dwExStyle
                , m_WndClsName
                , null
                , dwStyle
                , X
                , Y
                , PngImg.Width
                , PngImg.Height
                , MainFormHandle
                , IntPtr.Zero
                , GetModuleHandle(null)
                , IntPtr.Zero
                );
}

The problem is my fake form always in the topmost position. Is there a way to put the fake form behind the main form?
In other words, how do I set z-order between the main form and the fake form so that the fake form placed at the bottom of the Z order?

How to hide the fake form whenever the main form minimized or maximized, and move or resize the fake form whenever the main form moved or resized?

Thanks.

Why don't you override CreateParams instead of creating FakeWindow?

This example overrides default border and replace it with AERO. to get WS_ numbers, go to your Windows SDK and look under window.h for decleration

protected override CreateParams CreateParams
{
    get
    {
        CreateParams cp = base.CreateParams;
        unchecked
        {
            cp.Style |= (int)0x80000000;    // WS_POPUP
            cp.Style |= 0x40000;            // WS_THICKFRAME
        }
        return cp;
    }
}

Thanks for the reply,

I'm using Windows XP, so I think there are no WS_ for AERO.

when i said WS_ i meant WS_EX_NOACTIVATE and other. The one I post was uses AERO. It isn't limited for aero. It has all same as unmanaged code

When you say override CreateParams, did you refer to the main form's CreateParams? But then, where do I draw the png image files into?. Sorry, but I'm new in this so I'm still confused.

for painting try look into OnPaint event or you can even ovverride

I thought if I paint form's border with a transparent-shadow background (using png file), it will not become transparent unless I set the main form transparent too. And how to paint the shadow into the border which is located in non-client area?

To enable Form transparecy you need to enable transparent color.

this.SetStyle(ControlStyles.SupportsTransparentBackColor | ControlStyles.DoubleBuffer, true);

It seems that SetStyle only applied in client area. I can't make the non-client area transparent. Any suggestion?

In a book i am reading, this is formula for getting transparecy

displayColor = sourceColor × alpha / 255 + backgroundColor × (255 - alpha) / 255

ImageTraverser[^]
This link is very good. Create a snapshot and you can get pixel. Image.GetPixel is super slow, this example is very fast.

Alright guys, here's what I'm trying to do. I have an integer called rollcount1 in a class called Class2.cs. When I call upon a method in Class2.cs from Class3.cs to increase the value of rollcount1 by one (rollcount1++;), the moment it finishes increasing the value of rollcount1 and goes back go Class3.cs, and from there to Form1.cs, rollcount1 gets reset to a value of 0.

Does anybody know what's going on? Really frustrating >_<

Hi,

you really should spend some time and come up with realistic class names, you may not believe it right away, but it will help you in making fewer mistakes.

Without seeing any of the code, my best guess is you somewhere have an extraneous new Class2() and are suddenly facing the rollcount1 of a new class2 instance, which obviously is not holding the same value rollcount1 has in an earlier class2 instance.

Hey Luc Pattyn,

you had a good guess and based on your answer I was able to fix the problem, but it's slightly more complex than simply turning the ints into static ints.

And, Yeah I usually set the name of my classes to something appropriate, but this is a friends' project and he needed help on it, and I couldn't help so I decided to come to the professionals Smile | :)

Thanks again!

Make rollcount1 static.

Some more info on static here [^]. Warning - static is not always the best way to do things. I would suggest you also look at restructuring your code as has been mentioned in the other post.

Also, vote for an answer if it helps Smile | :)
