Im looking to make an advanced drawing program in vb.net as a bit of a project to occupy my time.im looking to make one pretty much like Paint but with gradients and other features, but im at a loss as to where to find such a tutorial.
View 3 RepliesI have a school project due in January to make a program in vb. The problem i'm encountering is making the actual login system. I only started using vb last year and that was purely console applications. So I am completely new to forms and I don't know ANYTHING...
The login system should be complex to an extent that it shouldn't just be a simple if statement. I have to make it so that users can create an account and that username and login will save somewhere where no one can access but vb can read from and to that directory.[code]...
I'm using using System.Graphics for my latest project (A simple 2D application). Problem is, it gets a horrible FPS and I'm only drawing 8x8 tiles (usually 10-12 is enough to bring it down to 12FPS).
A friend of mine suggested that I use DirectX. He also suggested XNA but I opposed because I don't want my clients to have to install the XNA distributional. DirectX is common enough (to my knowledge) and I can just include the dll's if I need to.
So, my search began. I've been looking only for DirectX 2D tutorials for VB.net. I've had no solid success thus far. In truth, all I need to do is be able to draw bitmap x at position pos.
I've been using System.Graphics and a hacked up bitmap as my buffer thus far so I'll go for any improvement that I can get.
I'm using VB.net so I'll be ok if you give my one for C#, I'm pretty good at being able to read it (and I have a nice converter too). I would just prefer VB.net to save time.
I try to implement undo in drawing program I want to save the bitmap after every drawing and push it to stack then when the user click the button it will change the image to the last bitmap saved in the stack here is my code
Private Sub PictureBox1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseUp
Xend = e.X
Yend = e.Y

View 2 RepliesI need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

Say I have 3 Buttons, labelled: Unit 1, Unit 2 and Unit 3. When I click on any button I want a drawing of that unit to appear on screen at a pre-specified starting point. Thereafter when I press any other one of the buttons the unit drawings appear alongside each other in a line. So I could end up with:

View 6 RepliesI have a university assignment, The problem, well.. in the short anyway; i have this form which is for placing orders. There is an "add product" command and next to it a list box. what I would LIKE to achieve is being able to click on add and then a query would come up asking for the user to input a product ID then check either yes or cancel. once that is done, I would like the database to search products by ID (obviously) and then display the product in the list box. the list box may contain up to 5 products and no more. there is also functions to remove individual products from the list box as well as clear the list box all together. in addition to this mammoth task, I also have a label which requires a total price. this would be the price of all the items in the list box, not in the database.

I have two tables:Orders OrderProducts - An order can have 1 to many orderProducts records associated with it.What I am trying to do (unsuccessfully) is to implement a GridView search using a LinqDataSource wherein the search returns Order results where any of the OrderProduct.Manufacturer columns contain a search query.
I was hoping the following would work, however it seems lambda expressions do not work within a Where clause of a LinqDataSource (in VB):

how to get this working within the LinqDataSource definition, or will I have to handle and set up a custom OnSelecting event?

View 2 Repliesat the beginning sorry for my english (=. Ok, I have two questions:
View 2 Replieswhat I've been reading the past 2 weeks and I want to make a Multi File Downloader.y goal is to have a TabControl, inside each Tab I'll have about 3 to 5 (maybe 7) CheckBoxes, each CheckBox is tied to a TextBox where the url goes (I attached the GUI I have so far so you can see better how I want it to be).Now so far the downloader is working fine, I can download whatever I have in those TextBoxes and it is downloading it only when CheckBox is checked.Here's my problem I want it to be a MULTIdownloader lol not a single file downloader like it is acting right now.
So my question is how can I do so when I check 2 or more CheckBoxes it starts downloading the files (it doesn't have to be simultaneity, it can start downloading the first one then the 2nd one etc).Also how can I identify which CheckBoxes are checked and which ones not?
Right now I am using If/ElseIf to control the CheckBoxes but I wonder if there is a better way to do it, because I only have 2 CheckBoxes so far, to test and if I do it like I am now it's gonna be a loooong code.Here's what I have.
Private Sub btn_download_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_download.Click If CheckBox1.Checked = False AndAlso[code]....
If is too complicated how could I do so everything saves in the same location as the downloader is?I've been reading around the forum also the microsoft documentation about VS 2010 (I'm not gonna lie, I haven't read the whole thing,

View 2 RepliesI have a server program. It logs all of the lines on the console textbox in their proper folder, named by their type: Logs\Year\Month\Day\Errors.txt There are about 7 types that it logs. All of these show up in the console window. However, I have check boxes that I want to toggle the types that show up in the console window on and off. For example if I want to hide the Error and System types, I want the rest of the types to show. I know I can do this simply, but if I re-check the boxes to show the System types as well with the others, I want it to show the logs in their proper place in the console window, and that I cannot figure out how to do.I am stuck on this problem and cannot figure it out. I know it involves much more than an If statement to display the types correctly in the right place on the console. Please help me out with some idea of what I need to do.
