View 1 RepliesI've inherited a lot of custom made software for an office, and, while managing it, I've found it performs differently from machine to machine.I mean, some controls get painted in weird ways in some machines but well in another, or just work differently, like in some machines clicking something selects it, and in the next machine clicking the same thing makes it editable.I suspect, o course, of the myriad of DLL the software loads

View 2 RepliesI am developing a hotel software product, and one of the features required is to be able to display the room numbers in the hotel, and then the status of them for each day of the month.
I am trying to create something similar to a DataGridView control where at the top the column names are the dates of the month, and to the left is the room numbers as rows. Please see the below screenshot of the function I wish to have. However I do not know what control or function they use to create this grid below (it is from an existing product). I need to not just be able to join multiple cells together when it is the same person in the room for multiple days, but also allow drag and drop ability.
Currently I have a DataGridView control and am able to simulate the below screenshot, however with a datagridview control I am unable to join cells across multiple columns nor allow drag and drop ability between rows.

If anyone needs any more info just let me know. Here is the process that I wrote:

View 2 RepliesI'm working on a WinForms solution in VB.NET. It's been a while since I'm mostly a web developper. So what I need to do is to replicate the behavior of Microsoft Office product for the Cut, Copy, Paste and Undo menus and toolbar. Which meens, I need to enable Cut and Copy when and only when there's some selected text on the Form. The Paste menu have to be enabled only when the is some text in the clipboard.
Do you have any ideay about how to accomplish that ? I probably would have to check some event in the TextBox's to check if some text is selected (MouseUp ?). Then in the Enter event, I would check if there's something in the Clipboard to enabled Paste menu..
I am developing an application which will keep track of various information about medical practitioners that are affiliated with my place of work. One thing that we are tracking, is their availability by time of day (morning, afternoon, and evening) for each day of the week (monday - sunday). Additionally we will store an optional comment about the practitioners availability, something like "Does not work during full moon."
The input/display form for this information will be table with days of the week as column headers, and times of the day as row headers. Check boxes will indicate whether the practitioner is available during the specified time.
I am having a hard time figuring out how to store this information in the database. The most obvious solution to create a table with 24 columns (21 for 7 days * 3 times, 1 as the primary key, and 1 for the foreign key referring to the practitioner, and 1 for the comment). Which is a crappy table, but at least it's easy to select and update.[code]....

If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form.
