View 10 RepliesMaking My Own Events - Read In Information From A Magnetic Stripe Card
Jan 13, 2009First off, what I'm doing here is trying to read in information from a magnetic stripe card, parse it, validate certain parts and go from there. I'm working on two classes... the first is CardClass and that represents the card itself (well, the data obtained from the card). The class is CardParsingClass. This holds all the card parsing rules.
At one point in the process, I will create an instance of the CardClass. That instance gets passed into the CardParsingClass.ValidateData function:
CODE:
This function steps through each of the card parsing rules and applies the rule to cardCurrent to see if it passes (i.e., is valid).
And here we come to the meat of it.... what I'd like to do is define an event called FailedCardReadEvent. Whenever I raise the FailedCardRead event I could write to the log that it failed, modify variables in the CardClass (particularly the state of the card read variable), etc. So, the way I'm looking to use this would be something like this:
CODE:
So as shown above I'm thinking I should code a FailedCardReadEvent in the CardClass. But I don't know how to do that.
I also don't see how this is different than just calling a subroutine. If I have to manually raise the FailedCardReadEvent isn't that the same as calling a subroutine?
I know I'm missing something but I'm just not getting it. I've spent some time googling this morning and read a few things but I'm just not understanding how it all works.
Loads Up 4 Images If Usb Stick Is Checked And A Different 4 If Memory Card Is Checked?
Feb 20, 2010project im working on for my course,the idea is a photo printing machine that loads up 4 images if usb stick is checked and a different 4 if memory card is checked. and then whatever image is selected appears in the big picturebox on the left [URL] i have 2 print size options set as radiobuttons, radiobutton 1 = 6x4, which costs 25cent per photo, radiobutton 2 = 8x10, and is 50cent per photo.i also have a textbox which will display the number of copies to be printed So here's my dilemma, when the print button is selected alongside one of the radiobuttons i want it to display a message saying something like this "you have selected (whatever the amount of copies)of this photo sized 6x4, or 8x10 depending on which radiobutton is selected, and i want it to display the total cost which is the number of copies multiplied by the rate for the print size selected, then an option saying "Do you wish to proceed" Yes or No.
I did something similar to this in class earlier in the year but cant remember it, it was an airline booking program with 3 types of payment cash, visa or mastercard,upon booking a message popped up saying there is a certain percentage discount for using visa or mastercard
[VB2005] Rotateflip Image Is Eating More Memory Than Non Rotated Image ?
Sep 8, 2009 I'm writing a program that print images in full page. I.E, I print image on A4 paper, landscape. When I print an image without rotating it (the image IS landscape), the image uses all the space of the page, and is not cropped. it is OK. The print job is about 1.5 Mb. When I print an image WITH rotating it (the image IS PORTRAIT ), the image uses all the space of the page, and is not cropped. it is OK. The print job is about 28 Mb. The images are about 2000x3000 pixels, and stored in JPEG files (about 2.5 Mb each). I suppose that the 28 Mb should be the "uncompressed" size of the picture, and 1.5Mb, the compressed size...
By the way, When I look at the task manager, my application memory usage grows by job size, which seems to be OK. It grows either 1,5 Mb if no rotation is occured, and 25-30Mb when rotation occured.
Since I can print hundreds of image at once, my print queue will grow abnormaly if I need to rotate all
Capture Raw Signal From WiFi Card As Would A Sound Card
May 9, 2012Is it possible to capture the raw signal from a WiFi card in the same way you can capture the signal from a sound card? (I already found code for working with a sound card and for drawing spectrograms) I'm wondering because it would make a cool radio-type project. I'd prefer a solution that integerates well with .net (VB or C#).My basic goal is to capture the ambient radio waves and build a primative "telescope" of sorts. Using the built in computer hardware is just the easiest way to accomplish this. If you have any other suggestions about how to accomplish this goal in a different way please post it as an answer also.

Oct 5, 2010I'm basically making an app to take screen shots in a game as I chat. There will be a bit more to it later, and I will likely be using PNG but that is besides the point for now.Whenever I take a screenshot and save, doesn't matter If I am saving converting quality or using system.drawing directly, the memory use goes up about 1.5MB per save. I'm rather new to VB.Net so I can't really figure out why...as far as I can tell I release everything.[code]Ihave tried setting it to nothing with no luck, and aside from that memory slowly goes up per time Enter is pressed. I'm not sure why data would be saving to memory when Subs and Functions are supposed to release data after use?

Interface And Graphics :: Load Image And Access Its Memory Buffer
Mar 31, 2011I have some questions about bitmaps and such. I am using the IDXSurfaceFactory::LoadImage Method to load an image and now I want to access its memory buffer, so I can do some direct memory manipulation and copy the content to another buffer afterwards (no BitBlit!). I managed to successfully use LoadImage, but I have no idea how to retrieve the pointer to the memory buffer and other informations. I want to basically know everything about, how and where the image is stored in the memory buffer.
Does windows always load images as BGR regardless of its original format? if not, how can I find out if the loaded image is stored as BGR or RGB. How can I find out how many bits each color has? How can I find out if the image is stored y-reversed? And if you load an indexed png for example, with one color marked as transparent, how can I find out which color is used for transparency?

Making Sprite Class And Cycling Through Image Arrays
Feb 2, 2012I am using vb.net by the way. From what I understand, Xna is not usable in visual Basic. Therefore, in order to create my characters, I defined a sprite class. Now my question is.... (I am drawing everything using a timer on the form btw by the process of invalidation.)... how do I use time to cycle through the images in an image array while the instance has no focus, and whilst the class inherits the "Control" class? Basically, how do i get these instances to act without user input? I want a character to eventually respond to user input, but I also need npcs that do not need any input in order to move themselves. Also, I need this in such a way that each instance's processes do NOT interfere with the processes of others. So that whatever timing I use does not also stall the whole window/form.
