Add a DateTimePicker, two TextBoxes and two Buttons to a Form
Add the following code:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click

I've created a custom DateTimePicker and implemented code I found on the web to allow customization of the BackColor of the dtp (Making use of WndProc). However, I've discovered that this doesnt work in Windows 7 with the XP Visual Styles option enabled in the project. How to make this work for Win7, without disabling the Visual Styles (the controls look ugly without them).
Below is the code I'm using:
Private _BackColorBrush As SolidBrush = New SolidBrush(SystemColors.Window)
Public Overrides Property BackColor As Color
Get
Return MyBase.BackColor
End Get
Set(value As Color)
[Code] .....
The backcolor of a default DateTimePicker control seems to be Color.White, but can this change based on a users theme colours and how do I find out what it is currently set to?(There is no backcolour property and DateTimePicker.DefaultBackColor returns SystemColors.Control which is not actually correct)I guess that if someone can confirm that this can't change then I am safe to hard code it? The basis of this question was not actually a typo, it was the fact that BackColor does not show up in my DateTimePicker control intellisense.

But to give the full effect of being readonly, I would like to implement the ability to change the Backcolor and disable the ability to use the calender. how to change the Backcolor and disable the Calender?

View 2 RepliesI'm building an app that is a basic daytimer type of app. My problem is that I can't get the textbox(Textbox1) backcolor and text to change when I need it to. For instance, if there are events for January 12 and the user clicks on the Jan 12 link in the Calendar control, if there are any events in the SQL table for that day it should populate the appropriate times. The funny, or not so funny, thing is that I have another textbox named "TheEvent" that I can change the backcolor and text on with the code below and it works fine.[code]...

VBbasic 2008: I have a readonly textbox in a panel. The background color needed to be change to white for a more "readable" text. The problem is when I set the panel "enabled= false", the only control that does not look "disabled" is my textbox because it stays "white"! Even if I set the textbox to disable, it stays "white". How do you change the default backcolor of a readonly textbox instead of "forcing" it to white? Is it possible?

Is there a way to change the forecolor and backcolour of a piece of text inside a textbox or a rich textbox?
Lets see if I can explain-I have a text box (rich text box) in a form. Inside the box, some data gets put in there- specifically insurance information.
Normally, the box doesn't need to change color to alert the user there's a problem with the text that's inside, because the information is usually good.But there are a few phrases that need to alert the user there's a problem.
For example, if the words "Not Found AS OF:" appear anywhere in the box, I need the background to show red.Or, if the words "Letter #1" appear in the box, it needs to show red. Absent of any key words, the box is normal (white).

View 2 RepliesThe title says it all, I'm having some difficulties with the combobox, The items in the list are "Black & Green" - Black will be the Backcolor of a Text box, and Green will be the Forecolor.The App I made is just a Mimic of a CMD, and replicates the output of the command into the Textbox. It's 100% complete, but I'd love it to have the ability to have different colors to choose rather than White and Black.

View 7 RepliesMy form has a TextBox with values like(e.g: P011112, C0212102) those are products lot numbers that the user enters. Then, what i want is that a DateTimePicker takes the first 4 digits as "MM-yyyy" and add 3 years to that date.
View 2 RepliesI have a TextBox that need to be case-insensitive. For example, I have this. If searchTextBox.Text = "Park" Then... I need results back if "Park" is typed or "park".
View 6 RepliesI would like to change the case in a Textbox to look like a proper sentence, so the first letter would be capitalised and all following letters would be in lower case.
For example:
original text: "this IS My Text"
output text: "This is my text"
It is easy to change texts/strings between upper and lower case...
vb
TextBox1.Text = TextBox1.Text.ToLower
TextBox1.Text = TextBox1.Text.ToUpper
... but how can I apply a sentence case?

View 5 RepliesI have a DateTimePicker for a product that has been dispatched to the customer.I would like to select the day with the datetimepicker and add to a textbox a 30 day warranty. I want another textbox to automatically insert and display the date that the warranty would expire.
View 12 Replieslet me explain in more detail so you don't get the wrong idea of what I'm trying to accomplish.If I have a button object, say Button1, on my form and I select it with my mouse, it brings up another form or dialog. If in the text field property of Button1 I enter &Button1, the B will have an underscore under it and if I hold down the Alt key and press b, it too will invoke the other form or dialog. I would like to also have the capability to do that with a datepicker field or textbox field.
Right now, I can set up several buttons with Alt-keystroke combos that work by default, but it seems like I have to write some form of keystroke intercept routine and test for the conditions I'm looking for and force the focus to the datepicker or textbox. Am I missing something? Is there a better way to do this? Or is there actually a way of setting up a label on a textbox or datepicker object.
Kind of like when you're using MS Access and building a report, the fields have a leader that you can type a label in. That's what I'm looking to do. So if the label part of the datepicker field says Date: if I press and hold the Alt key and press d, it will invoke the datepicker field (aka open the calendar for selection).

I am creating a login form for an application, everything is ok but I have been asked to make the user name and password text boxes case sensitive, by which I mean if a user entered the following
User Name: vbwizzard
Password: youwish
a error message would be shown If the user entered
User Name: VbWizzard
Password: YouWish
The information would match what is in the database and the user would be granted access.I just need help with making the text boxes case sensitive, the rest I am ok with.
I populate a hash table with the name of a control as the key and the control itself as the value using the following code that loops through my code on start-up:
Private Sub Populate_Hash_Table()
For Each ctrl As Control In Me.Controls
For Each member As Control In ctrl.Controls
[Code]....
This method works effectively, but the only problem is I seem to get a preformance hit as it takes a second to set the current control to false and the new one's visibility to true. What way should I modify my code so that it works more efficiently?
