The overall goal is to be able to access a pop-up keyboard through an application that I am making in MFC.
I have created a dialog box with an empty text field. I would like to be able to click the empty field and have an onscreen keyboard to enter in the data field.
Is there list of functions or tutorials that anyone can provide me with to be able to perform this function? Ultimate I will be making the keyboard from scratch, so any guidance would be useful.
My first thoughts (I might be wrong someone might correct me if i am wrong.)
1)Create your Keyboard Ui in an MFC DLL and export the KeyBoard Functions like LaunchKB(Int screenx,int screeny) and CloseKB()
functions.
2)I would subClass CEdit and CRichedit such that when the edit control gains or loses focus it would call LaunchKB() function with windows ScreenX coordinates where the keyboard has to be displayed or CloseKB().
3) A callback function registered to dll ,which would get called for every click on the keyboard with characters clicked and these characters are to be displayed in the edit control.
This is just my thought ,there may be better ways to implement as well.
I had a question about Dialogs in VB.NET. I am working on a point of sale program, and at one point during a sale, I have a few windows that pop up. For example, a user will go into a sale that is window A. In window A, they have the option of entering products, etc., and if they choose a 'repair' product, it opens window B, allowing them to choose options. In window B, there is a button that pops up window C that allows them to attach products TO the repair. My issue is with window B opening window C.
Because I open window B as a Dialog (in order to check if DialogResult.OK is true), any window I open with B is non-touchable, as B is a Dialog and requires attention before going to any other windows/forms.
My question is - is there any way to still use a dialog, but allow for manipulating other open forms while the dialog is up, and if not, what would be the best way to check if the user selected OK, or cancelled out of the window?
The only solution I can think of right now would be to open window C as a dialogue as well (it's actually a UserControl, and I'm still trying to find where in the code it's actually getting openned/called), or to create a variable that is passed in to the form, and then passed back out when it's closed, that basically sets a flag to either continue or cancel...
Any advice/ideas??
If I were to explain this using code, this answer would be very long, so instead I'm going to give you a high level overview.
.Show() vs .ShowDialog()
The link below will take you off to Microsofts website to explain the technical differences between these two. However in laymans terms, .ShowDialog() will create the form where it is the only window allowed to have focus in the application. Forms that are called in this instance are hierarchical, in that if you open them in order of 1,2,4,3 then they must be closed in the 3,4,2,1 order. Forms that are opened with just .Show() can be focused at any time.
How to: Display Modal and Modeless Windows Forms
Form.FormBorderStyle property
This property controls how the OS will display the window. The different options under this selection changes the way the window behaves. Depending on the options that are chosen you can make a window that only has a close button on it, or it may not even have a title bar at all. Setting this option to None will take away all controls of the form and only leave you with the Me.ClientArea to work with. When you want a completely custom GUI, this is how you do it but you have to implement your own controls for everything, closing the form, size handles, the ability to move the form on the screen, etc...
Form.FormBorderStyle Property
Passing data between forms
When someone asks how to pass data back and forth between forms, they are usually talking about modeless forms that were created using .Show(). The most common thing I see on SO is to use the tag property of an object (a form is an object that has this property too) to pass data back and forth. While I won't say this is a bad practice, I will recommend creating public properties on your forms. These can be set from a separate form and you can perform additional actions when setting the values (be careful though, this way of doing things isn't thread safe). If you are using a Modeless form as though it were a Modal form, then you can simply override the .Dispose property to return a value or you can create a method named DialogResult that will return the value you need. The caveat to using a DialogResult or similar method is that if the form has been disposed then you can't access the value you wanted to return.
You can use myNewForm.Show(Me) for the Window you want to be shown as a dialog. This will show myNewForm as a child of the current form, but lets you interact with the current form.
Hi I have a VBA application with a combobox selection option.One of the combobox option is Other which when user select that option an invisibled label will pops up and prompt the user to fill the txtOther control.now my question is how I can get rid of the prompted label and make it to invisible after user fill the txtOther and move(focused)in other control?
here is a shot of my app:
Thanks for your time and help
It depends on how often or when you want the check to be done. I couldn't find a good reference to show you all of this, but you can view your VBE.
Within the code behind your userform you can use events for the text box.
If you want the check done every time you leave the text box:
Use the TextBox_Exit event.
If you want it to fire whenever the contents are changed, used TextBox_Change. There's lots of options, but based on your explanation I'd probably use Exit.
This answer shows some syntax examples for using the Textbox_Exit event.
Do anyone have a solution for handling a vbscript inputbox with watin, and to be clear this is not the same a javascripts prompt or vbscript msgbox or etc....
I have and used handlers for those but cannot find a way to handle the input box and i do not have the pull to get the developers to change the code to use prompt and javascript like they have in some many other places in our old vb6 systems.
You should create a custom dialog handler that can handle the window. The trick to doing that is to get spy++ and match the right window style. Another method might be to call the document.eval method and close it using javascript.
With my Application (vb.net) I am trying to scan Excel files some of which have ActiveX Components.
When running my Application, I am getting a pup-up window in Windows Vista Environment with Office-2007 having button OK and Cancel button to proceed.
But my problem is the scanning is not proceeding even after I keep on pressing the OK button. Now I want to continue with my application while pressing the Cancel button; i.e. just to skip the file. Is it possible to capture the response from the cancel button? (As this is a message box from another application, i.e. either from Vista or Office-2007, I'm not sure).
My main motive is to just ignore the message box to proceed....
Can anyone please help me out there....
Thank you....
The DisplayAlerts property of Microsoft.Interop.Excel.Application may help here.
If set to FALSE then Excel automatically chooses the default option on pop-up boxes.
Whether or not this applies to ActiveX controls I don't know but it may be worth trying.
