I know how to check if a particular button has been pressed but I basically want to disable the delete button when ever the listbox has lost focus. I am having issues with the fact the button gets disabled before it receives the message. Is their a way around this that is non hacky?

I have been learning C# so I've been dragging and dropping. I have a "First Name" and "Last Name" text field. I want to add this to a combo box called something like "User List", which will list the last named then the first names. However I figure I can work with something that can get me to store the names in the combo box.
So. I have two things I need to know:
What do I have to do to have when the button is pressed, add to the combo box?
Is there a way to retain all the entries I have entered? Or no?

I am currently using Flash. Here are two images I will be referring through without this post:
1: [URL] ....
2: [URL] ....
So basically, when I click the generate buttonon the first image it takes you to the second image. What I want is when I click the generate button it comes to this screen, aswell as choose a random word from each list that I will make (Who List, What List, When List, Where List, and Why List) and place the word next to its position. When you click New Idea I want it to also generate another set of random words from the lists. How can I do this?
How you can make a c++ program that checks to see if the user presses the power button on their computer? And if so, how?

The following 2 codes are almost identical, only that the switch statements are slightly different. The 2nd code has the issue of requiring an additional enter key to be pressed when I enter '3' as input to exit the program.

I need to run some operation if a key from keyboard is pressed. so I go with
Code: c=getchar();
to get it read. yet the user could press a key anytime; so I'd need some if-loop. no plans on how it'd look like though...I suppose something like this below wouldn't work right?
Code:
if(getchar()==1){

I am new to C++ , i want to know how to check if a key with modifier is pressed.
When I use GetAsyncKeyState() it gives me error identifier not found.
How would I detect if any letter key is pressed. Would I have to use GetAsyncKeyState() for every letter key? Or could I have some kind of loop going through all the hexadecimal values for every letter? I don't know how I would go through hexadecimal values with a loop.
View 6 Replies View RelatedSo I'm in the process of building my 2D game in Allegro5, I'm building a side platform game and at the moment I have a sprite being able to walk left right and jump. What I want to do is put a time delay on the jump function so that when a user presses the jump button and the sprite has carried out the jump function I want there to be a 1 or so second delay before the jump button actually carries out the jump function again.
I have quite a bit of code so not sure what bits to place in here, I'm more looking for a way of doing this, so providing me code isnt really needed just a way it can be done.
Things that might be useful to know:
At the moment I have a timer initialized in allegro which is used with my FPS int to mean that my game runs at 60FPS.
I have a bool bIsOnGround which maybe could be used into this, I'm not sure...
So, I've been working on a project recently, and the only thing remaining to do is a detector to whenever down arrow key is pressed. The down arrow key can only trigger when a certain check box is checked and this will have to work with a timer either. The problem is that how to make the down arrow key press detector(I've got the check box and timer ready tho).
View 10 Replies View RelatedI would like to know how to press a key as if it had been pressed on the keyboard in a program. I would also like to know how to read input from a xbox 360 controller. I want to know how to do this so that I can add joystick support to a few mmos that I play that do not already have it.
BTW I am using C 99
My code is given below:
cout<<"1. runtim";
cout<<"2.tims";
cout<<"Your selection will be automatically neglected within (function to be inserted for time ) ";/* insert timer here */
cout<<"What kind of process u need to do";
.

I have 2 questions
1.the timer function has to be such that when any key is pressed in between the specified time its has to stop its counting and go to the nest line and functions . i checked sleep function but if any key is pressed its does not break out of the sleep program and execute the next command
2.and if the timer has completely finished running then it has to skip few lines and execute the program .
In a SDI app, I constraint the mouse to move only an horizontal direction, if "Shift" key is pressed ... here is the code:
Code:
void CTestMouseView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags) {
// TODO: Add your message handler code here and/or call default
if(GetKeyState(VK_SHIFT) < 0) {
CRect rect;
GetWindowRect(&rect);
GetCursorPos(&m_point);
[Code] ....
Nothing complicated, and it works well ... except one thing: when I press the shift key and the mouse is moving by SetCursorPos, is moving pretty slow ... why ? I can not figure out why ! For testing, I attached the test project ...

View 4 Replies View RelatedI have a winform that I added a button to at design time.
Then I decided to add a groupbox to the form because I want to add a few more components to the gbox.
I notice if I add a gbox at design time and add components onto the gbox at design time, then the components show up when I run my app.
However, if I add a gbox after my form already has compoents on it, I can't see some of my components.
How do I move an existing button onto a new gbox so it shows?
I thought this would work but it doesn't:
gboxSettings.Controls.Add(btnChecklistFonts);
I was wondering if it's possible to push a button on a website programatically. Unfortunately the button link is invisible, otherwise I could simply use the URL it links to. So is there a way to do it in c++ and if so, how?

View 3 Replies View RelatedI have begun switching from WinForms to WPF and I'm having a hard time understanding the new concepts. In WinForms, I had a few User Controls, custom drawn using shapes (rectangles, ellipses, etc). They had some unique properties, like "Flashing" (setting this property to True and setting the "Flash Interval" property to 500 would have resulted in the control changing its background color to white and back again, every 0.5 seconds), "Beeping", etc.
I have tried to replicate these controls in WPF/XAML and so far managed to draw the shape. However, when it came to implementing a custom property that would redraw the background color of the rectangle every interval set by user in another property, i got stuck. The property is being set, but it doesn't change the background color. Alternatively, i have tried this method, with the same results (i got it to show in the "Properties" window in Visual Studio, i can set it, it is being stored in XAML, but it doesn't affect the background.
C# code behind:
public struct LCARSColors
{
public static Brush DarkBlue = (Brush)(new BrushConverter().ConvertFrom("#FF3366CC"));
public static Brush LightBlue = (Brush)(new BrushConverter().ConvertFrom("#FF99CCFF"));
public static Brush Pink = (Brush)(new BrushConverter().ConvertFrom("#FFCC99CC"));
[Code] ....
If i use this line (commented in this code sample):
<!--<SolidColorBrush x:Name="MySolidColorBrush" Color="{DynamicResource DarkBlue}" />-->
The background is colored in DarkBlue (as defined). But if i use this line:
<SolidColorBrush x:Name="MySolidColorBrush" Color="{Binding BackgroundColor, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" />
Nothing happens, the rectangle disappears entirely. If i add this to the above line:
FallbackValue=LightYellow
The rectangle is colored in LightYellow, meaning that the property is not accepted and the fallback value is used. Why?
I decided to code my own GUI menu. getting to another page from a button click. I have added the event handler I think (click="Button_click") then in the event handler I have added this:
private void Button_Click(object sender, System.EventArgs e);
}
Response.Redirect("Login.xaml");
}
After researching it says either to use
Response.Redirect("Login.xaml");
OR
Server.Transfer("Login.xaml");
Neither of these work, underlining "Response" and "Server" as an error saying "A namespace cannot directly contain members such as fields or methods."
NOTE: MY MAIN GUI PAGE IS CALLED "mainpage.xaml" THE CODE ABOVE IS STORED IN THE "mainpage.xaml.cs" THIS MIGHT BE RIGHT OR WRONG BUT I'M NOT SURE SO I AM LEAVING SOME EXTRA INFO!
I am working on a website so you can order online for a restaurant. I currently figured out how to get values of all checkboxes and dropdownlists but i still cannot seem to figure out radio buttons.

How can I make a button transparent? I know i can select color Transparent, but that takes the background color, and i want to be transparent all because i have a video behind it. What can i do? :o3
I have a video and there is some buttons which should be pressed. I could insert the buttons but they are semi-transparent...
I've been doing some looking and this example seems like the common way to remove the close button on a wpf window. Other than catching the on_click event or using that example, is there no better way to disable/remove that button?
