Re: Entity FrameWork, pass entity between forms

The easy way is to just pass the customer ID, create a new context and retrieve the customer record using the id and manage from there.

I nicer solution would be to implement MVVM and data binding. There'd be a learning curve if you're not already familiar with the concepts.

Perhaps if you gave more detail and explained what EDM and SDM are, you might get some responses.

Hi All !
the size of my exe file is about 1.5 mb .I just used Microsoft.Office.Interop.Excel.dll and Word in preferences.
thanks for any help me to introduce a way to decrease the size of Exe file.
Regards !

Normally in a small application, the app's Icon (and any other included images/resources) are the biggest bloat.

Obfuscation will not only make the exe smaller but also protect your IP.

void GetDataFromDatabaseSortedByCustomerName()
{
    int customerId;
    //more maintainable code with meaningful naming
}

Obfuscated

void a()
{
    int a;
    //more unmaintainable code with meaningless names like b, c, x
}

The obfuscated IL code is going to be smaller

Trouble is, it does absolutely sod all to protect your IP.

I definitely see obfuscation as a deterrent. At least it's going to cost them more to reverse engineer.

But sure if there just hunting down algorithms, it's pretty well useless.

And you don't now. Obfuscation does not protect your IP. As a deterrent, it is next to useless if someone has a reasonable toolset available.

handling of paint event

Good day everyone. I have panels with text and images. During scrolling, painting the entire panel becomes slow. I'm therefore trying to paint only the invalid rectangle from Graphics.ClipRectangle. Processing was still slow so I had to step through the code and realised something.

I realised the paint event handler is called twice. In the first call, not all parts of the panel become invalid. I am able to get the invalid rectangle for painting.

However, after drawing in the invalid rectangle and the paint event handler exiting, the paint event handler is immediately called again but this time the invalid rectangle comprises the whole rectangle for the panel control on which i want to draw.

Thus drawing takes place twice, first for the smaller uncovered portion during scrolling, and second for the whole panel which causes the whole panel to be drawn again.

Is there any way to stop the whole panel from being invalidated after drawing only in the uncovered part of the panel during scrolling? It will really help to speed up processing. Thanks.

Are you invalidating the (entire) grid?

Can you post the painting code?

Printing Envelopes from Manual Feed

Hi there,

Really stumped with being able to Print an envelope from my C# WinForms application.

At the moment we print from Word with the document size/type set up as a C5 or a DL envelope. When printed the printer will request a C5 or DL envelope to be placed into the manual document feeder before printing.

I want the application to be able to do the same but at the moment I am having no luck. Here is the code I am using:

Code:

/* aPD is a PrintDocument object */
aPD.DefaultPageSettings.Margins = new System.Drawing.Printing.Margins(0, 0, 0, 0);
if (radSizeDL.Checked)
{
    aPD.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("DL Envelope", 220, 110);
    aPD.DefaultPageSettings.PaperSize.PaperName = System.Drawing.Printing.PaperKind.DLEnvelope.ToString();
}
else
{
    aPD.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("C5 Envelope", 229, 162);
    aPD.DefaultPageSettings.PaperSize.PaperName = System.Drawing.Printing.PaperKind.C5Envelope.ToString();
}
aPD.DefaultPageSettings.Landscape = true;
aPD.OriginAtMargins = true;

aPD.PrinterSettings.Copies = Convert.ToInt16(numCopies.Value);

aPD.Print();

I am quite happy to upload the code for anyone to see if they can help me?

Please help!

Thanks.
