We have become disenfranchised with our med records scanning package and are doing in house development to create our own. With most of the interface built out, the monster of calling the Fujitsu Twain driver and pre-setting scan options is what I am looking for. Fujitsu does not have an SDK available on their web for this.

I'm using VB 2010 and I'm trying to use combo boxes on a current project but I'm not familiar with the code. I would like to set values to certain options in the combo box.
For example, if inside the combo box I listed the options:
Dog
Cat
Bird
I want dog to be set to = 1
cat = 5
bird = 12
To go further into depth, the code probably looks something like:
If cat.selected then
pet = 1

View 3 RepliesI'm a newbie programmer taking an online Intro to VB class and would like some opinions on this code. This program is supposed to add or multiply at least 2 numbers together and display them in the result box BUT, the add and multiply buttons are disabled until 2 integers are entered into the list box (transferred from the text box to the list box). I don't really want to get ahead of the teachings that we've had so far so I'm trying to stick with what they show in the examples and text, or at least what parts they show so far. It's pretty rough as I haven't had a chance to test it yet since I've been at work all day. When I get home in about 6 hours I'll check and try to refine / incorporate recommendations.

View 1 RepliesI have a .net Forms Application with webbrowser control. I have a html file loaded in the control. I want to set Margins, Headers and Footers and orientation from the code itself for printing that document...
View 1 RepliesI am in need of a form that shows various options, exactly like the Options in Visual Studio. Since there are so many options I too want them categorized, with a TreeView to the left taking care of showing the right category.The usual 'easy' approach here would be to just place a TreeView control on the form, add some nodes, and give those nodes a tag or key that corresponds to a panel or UserControl with the options for that category.Since there will be a lot of options however, this is not really feasible design-wise; the form would be cluttered with possibly 50 panels, all of which I would need to select and bring to front from time to time to add controls to them that represent the options.
So I decided to create a custom control that does exactly that. The control is very similar to my Wizard usercontrol, users can add OptionsPanels at design time, which inherit Panel and simply represent one panel of options. When they do, the panel is added to a container panel, and at the same time a TreeNode is added to a TreeView. The control uses a custom ControlDesigner to handle design-time clicks in the Treeview, selecting a different node would select and bring to front the corresponding panel, allowing the user to add the controls he wants.
Due to the design time support the problem of having 50 panels is no longer present, only one panel will be visible at a time and selecting the right panel is as simple as selecting the corresponding TreeNode, just as during run-time. Anyway, I got all this working, but only for a single 'level' of categories. As you can see in the Visual Studio options, there can be multiple levels of categories. For example, the Environment node has a bunch of children, where each child represents one 'options panel'. There can even be deeper nesting, see the Text Editor node for example.Let me begin by drawing out the basics of how my control works so far.
The main control is an OptionsView control, which contains a SplitContainer with a TreeView to the left and a OptionsPanelContainer to the right. The OptionsPanelContainer is merely a Panel to which only OptionsPanel controls can be added, and which raises events when this happens, as well as when OptionsPanels are removed from it. An OptionsPanel also inherits Panel, and these are the actual panels the users will see in the control, one for each option category.For now, each OptionsPanel has exactly one corresponding TreeNode (and vice versa). In the Visual Studio options, each 'parent' category usually has a 'General' node as the first child, and the parent and this General node show the same option panel, but I am ignoring that for the moment.
The OptionsView control has a property Panels that returns the ControlCollection (Controls property) of the OptionsPanelContainer (in other words: it returns a collection of OptionsPanels that are in this container panel).
vb.net
<Editor(GetType(Designers.OptionsPanelCollectionEditor), GetType(UITypeEditor))> _ <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Panels As Control.ControlCollection Get Return Me.PanelContainer.Controls End Get End Property
A custom CollectionEditor for this property takes care of the designer: even though the property type is ControlCollection, the CollectionEditor knows it should create instances of the OptionsPanel control instead of just Controls.When it does this, a corresponding TreeNode is also created and its Tag property is set to the OptionsPanel. Vice versa, the Node property of the OptionsPanel is set to the node. Hence the node and panel both know their corresponding object.
vb.net
Public Class OptionsPanelCollectionEditor Inherits System.ComponentModel.Design.CollectionEditor Public Sub New(type As Type) MyBase.New(type) End Sub Protected Overrides Function CreateCollectionItemType() As System.Type
[code]....
So far so good, this all works fine. I can add Panels via the designer and when I do a new TreeNode appears in the TreeView. I can select this node and the panel becomes visible (comes to the front).Now, I am a little stuck. How do I implement child option panels? And more importantly: how do I let the user add child panels?The most logical choice I think is to let each OptionsPanel have a property (ChildPanels or something) that returns the child OptionsPanels for that panel. Once the user selects an OptionsPanel then, he can look in the property grid to find its ChildPanels property and add child panels to that.
There is a problem though: what would this property return? It must return a ControlCollection of some container (this is, I think, a requirement for the designer features to work, otherwise panels are not added to the Form.Designer.vb file). But there is no container. I cannot add them to the OptionsPanel itself, that would make no sense because the parent OptionsPanel has its own set of controls (the options itself...), there cannot be another (fully docked) Panel on top of those obviously.The container of the main OptionsView then? That is not an option either, its Controls collection holds ALL OptionsPanels, not just the children of the selected panel. I cannot 'select' only the right panels either, that would require me to return a new instance of ControlCollection, it would be impossible to return the actual ControlsCollection that holds merely a small selection of its controls.

The program that I am creating needs to click on an image in a web browser. I have saved a bmp of the image and was wondering if there was a way that I could scan for the image in the webbrowser, and once found send a silent mouse click. Silent in the fact that it doesn't move the mouse. And I would normally use invokemember but the button is an image, not a "button". So I need to scan for it.

View 6 Repliesi have a scanner set up which scans .bin and .iso files and returns the crc32 checksums (then displays various info based of that etc)
Im looking into adding support for .rar and .zip files, so the end user wont have to extract there files to scan them, how ever that adds to many variable for the crc32's based of what each persons compression is etc. So what about scanning the file inside of the rar/zip file.
So would it be possible to scan a rar or zip file, and get the crc32 of the .iso/.bin located within that archive?
A way to scan to whole screen, and find a specific color on it - and after that move the mouse over the color.
This is what i would like the process like, so you guys can have a better idea:
1. A timer that scans the whole screen after a specific color every 5 seconds.
2. When the color appear on the screen, it'll move the mouse to the x, y.
3. After that I'll run some code (i'll hopefully find out of that myself)
I actually don't care how the color should be found. If it's a RGB it will be 255, 209, 102 it should look after. Or maybe it could scan the screen after a matching bitmap. And it's not just 1 pixel I want to find the color of, it's the whole screen I'll like to have scanned for the color, and if the color is found - the program should react.

View 5 Repliesi have various options in my app, some complex some not, these 2 save on application exit and reload on application start themes, and layouts. There selected via a comobox each.So onto the question, how does everyone create options menus? With out using a menustrip/toolstrip?
The method i was using , was to have a picture box show a panel when it was clicked on, the panel had all the various options etc on it. This idea worked great, but meant working in design mode was a pain because the panel and everything on it had to be moved round to see the items under it on the form.
So today i decided to see what other ways i can implement a menu, and i changed it so the picturebox/button now opens a dialog, and all the options etc are on that dialog, this works great except options such as the combobox 1 and combobox2 last used setting (text data binding) doesn't load when the application is started, they only load when you go into the options. Which defeats the point, if a users going into the options just to load the settings its useless them been saved.
The time to initialize the dialog (for it to appear and be click able) is 5 - 15 seconds, not alot i know but the 1st method of using a panel it initializes instantly, but then its never really closed just made hidden, so i uses more system resources.So how does every one else implement there options menu?
