I'm making a magnification program that has a form that follows the mouse around but I can't figure out how to do the magnification part. I thought of using a picture box and somehow get the image that would be behind of the form and just zooming in on it a bit.
View 1 RepliesI have a routine where I click on an image in picturebox1. When the user clicks I need picturebox 2 to show a section of the image in picturebox1 centered on the users click but zoomed in. I have the following function which is doing exactly what I want it to do (except properly zoom in.) I have been able to achieve something that appears to be a zoom but it no longer centers on the clicked point.
Public Function magnify(ByVal position As Point, ByVal main_pic As PictureBox)
vert2.Clear()
horz2.Clear()
Dim img As New Bitmap(pic_magnify.Width, pic_magnify.Height)
Dim gr As Graphics = Graphics.FromImage(img)

im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts
1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers
2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly
3. the config files
anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.
my requirement is that i have to count occurrence of a certain date and between two months
suppose i have 10-jan-2012 now i have a date range 1-jan-2012 between 1-feb-2013 my requirement is that if i find 10-jan between 1-jan-2012 between 1-feb-2013 irrespective of year i know that 10-jan will come twice between 1-jan-2012 between 1-feb-2013 i am not understanding how to do this.i meanto say that i have to compare only day and month part of the date which will solve my problem

rx_str_buf(str_cnt) = CStr(Convert.ToInt64((Hex(rx_str_buf(Factor + 7)) & Hex(rx_str_buf(Factor + 8))), 16) +

View 3 RepliesThe following code reads an XML file and selects the CREDIT_SCORE node with the lowest value. Works fine if there is always a CREDIT_SCORE node. However, I get runtime errors if a PLUS_BORROWER node does not always have a CREDIT_SCORE child node (especially the first PLUS_BORROWER). I added /CREDIT_SCORE to the end of the XPath (and removed scoreNode references) and now it always selects the minimum CREDIT_SCORE. But I do not get the PHONE_NBR.
First - getting the minimum CREDIT_SCORE in a single XPATH is my primary need. And adding the /CREDIT_SCORE to the XPATH accomplishes this.[code...]
I've spent a while searching around and I can't find a solution to this:I have a transparent, borderless form that displays a clock. I can load this just fine, but I want the clock to be part of the desktop, so it cannot take focus, is behind other applications, and is not hidden with Win+D (similar to applications like RainMeter).
I need the solution to work with VB.Net (I'm using 2010)

View 7 RepliesI am trying to figure out the best way to implement a certain part of my model.I have an entity named Customer which has CustomerLocations (1-*) which have SalesOrders (1-*) which have Invoices (1-*).I want to allow them to have multiple addresses (Billing and Shipping) per customer and per location. I want to store those values in the sales orders and invoices, not a foreign key, what if they delete one of their addresses later down the road.I have tried complex types, but then they can't have multiple, can they? And having an Address entity, customer --> address (1-*) is ok, but a bit clumsy. How would you have a collection of billing and shipping addresses.?

Is there any way to download only a part of a web-page? What I have is a program that downloads periodically (every 5 sec) a web-page and displays some real time information. So I would like to minimize the bandwidth as much as posible.
I have seen that many download managers have the ability to resume a download, so they actually have the ability to start from somwhere in the midle. So can I do that with a single web-page and without messing with the sockets if posible?
