IIRC, you have to use WinZip's command line support utility to do something like this. Never used it myself though.

You might be better off using an open source, third-party, .NET compliant library that is better suited for programming than using WinZip. This might help: Google Search for open source zip library .net[^]

I've used DotNet Zip and it worked fine for what I was doing.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

I want to make magnifier for image.so i want 4 pixels works as 1 pixel for image which in picBox and when i draw on that image than also 4 pixels works as 1 pixel.i sent a small code which only draw large image but not change pixel size.so give me some idea for change pixel size of that picbox.
Thanks
"This is code of PaintEvent of picbox"
picbox.image=image.fromfile(anyfile)
dim bm as bitmap
bm=picbox.image
Dim wid, hig As Single
wid = bm.Width
hig = bm.Height
wid = wid * 2
hig = hig * 2
Invalidate()
e.Graphics.DrawImage(bm, 1, 1, wid, hig)
PicBox.Width = wid
PicBox.Height = hig

You can't change the pixel size of a bitmap, a pixel is always a pixel. It sounds like all that you want to do is to display the image at double scale, which you already have done. If you draw on the bitmap it will show up scaled when you display it.

Don't change the size of the control from the paint event. That will cause another repaint.
Despite everything, the person most likely to be fooling you next is yourself.

Hi,
none of the code you have shown belongs in the Paint handler of a PictureBox,
because 1) a PictureBox does its own painting anyhow, and 2) the code
shown should not execute every time the PB needs being repainted.
There are two ways to do what you want, depending on the details of what
you want:
1.
simply scaling up an image is something a PictureBox does naturally.
Just make the PB twice as large as the image is, and set its
SizeMode to PictureBoxSizeMode.StretchImage
This can be handled in the Visual Designer, without adding your own code.
Doing so the PB will use interpolation to calculate the new pixels,
which is fine for displaying pictures etc.
2.
if you want to replicate the existing pixels (e.g. because you want to
create a pixel editor), without calculating new pixels, it is a bit more
complex. There are again two ways:
2a.
calculate a new image yourself, twice as large; use two nested loops,
and the Image.GetPixel() and SetPixel() methods, unless performance is
very important (then use unsafe code and pointers)
Do this in a method that runs only once, e.g. the Form's Load handler.
2b.
Use a Panel instead of a PictureBox, provide your own Paint handler that
sets Graphics.InterpolationMode to InterpolationMode.NearestNeighbor
and draws the image yourself with Graphics.DrawImage.
If the borders need to be accurate too, you need a more elaborate DrawImage
overload that allows you to apply a translation over half a pixel in both
dimensions.

There really isn't any faster way. If you're retrieving many, many records, it's going to take a while. This also depends on the structure of the database, any indexing, and the SQL statement you're using to retrieve them. If it's just a simple SELECT, like SELECT * FROM table, and you're using the SQL data provider, there's nothing you can do to speed this up.

Is this a 100% complete backup everytime, or are you only add new data? What are the requirements? This makes a HUGE difference in how you should attempt to accomplish your goal.
If you only have to record the differences, then you could transfer only the new rows, updated, etc. Another option would be to use DTS. Alot of options, but require some effort in developing the method(s) in filtering and transferring the data.

Good. Take two of those tiers (the business layer and the database layer) and put a new presentation layer on it.

you have to create it.

I'm finalizing a proposal for a potential client who wants to upgrade their VB6 application to .NET. I hate to reinvent the wheel, so I'm wondering what tools or scripts exist to automate the conversion process.
I am aware of:
Microsoft's Code Advisor
Aivosto's Project Analyzer
Microsoft's Upgrade Wizard
Artinsoft's Upgrade Companion
Code Architects' VB Migration Partner
Great Migration's gmBasic
Microsoft's VB PowerPacks
Microsoft's Interop Forms Toolkit
We're planning on using 1, 2 and 4.
Are there any other tools, utilities, scripts, etc. to automate the conversion process?
