C Sharp :: Button Click Continuously Until Stop It
Apr 27, 2014
My question is how the button click mull ti times on page load in C# windows form??because in my project i am working on video for LAN based Skype in which i use 2 pictures boxes one for capture images and another for display .. so i want that on page load picture box capture images until i stop it .. following is my code :
I made 2 forms and Form2 has buttons with images like planets and game wallpapers etc. When I write the code for button:
this.BackgroundImage = new Bitmap(Properties.Resources._8_8008_by_amplifier404); this.BackgroundImageLayout = ImageLayout.Stretch;
// where _8_8008_by_amplifier404 is name of the image located in resources
It only changes background in form which has those buttons as long the form is used. Once I go back to form1 it's changed to null. How to set background in all forms with a button click which will be there until another button with an image is clicked.
var db = Simple.Data.Database.OpenNamedConnection("sqlConn"); DataTable dt = gridRatingEventHistory.DataSource as DataTable; string dateString = DateTime.Now.ToShortDateString(); dt.Columns.Add(dateString); gridRatingEventHistory.Columns.Add(new GridBoundColumn {
[Code] .....
if you look at 1st image 1 you can see what it looks like -- when i hit the button i just want a blank column to show next to the last column however i get image 2 results how can i fix this.
For now the app creates a new DateTime property which is binded to a label and shows the user the current time. Eventually I want to have the ability to select the timezone you are in, change font/background colors/etc etc... But that is all in time. My current step that I am trying to implement is having a button click (Binded to an event method) change screens. I find it hard to explain in words, but I would like the same Window to be used, just have different functions on the other when the button is clicked. So for example...
The only way I have found to do this so far is to create a whole new form or create tabs. While those are all good and have their place. I know that I need to start breaking up my code into classes, I am developing a bad habit throwing everything into the MainWindow Class...
I'm new to c# and have created the following method to trigger when the user clicks on a command button. When I try to run this page, I keep getting the following error and can't work out what I'm doing wrong...

I've created a new dialog in my MFC dialog based application. the new dialog contains 5 control buttons. The following happens and I don't understand why?
1. click on buttonX. (result ok, OnBnClicked message is sent) 2. click on on any place of the application, but not on the dialog.(removing focus from dialog) 3. click again on buttonX (FAILED, OnBnClicked message is NOT sent). but if instead I click on any other button in the dialog (result ok, OnBnClicked message is sent).
And when I do:
1. ... 2. ... 3. click on the dialog area just to set focus on the dialog again 4. click again on buttonX. (result ok, OnBnClicked message is sent) **I need to do step 3 only if I want to click again on the buttonX! why?? I think it related to SetFocus() but I m not sure how.
I've tried different style like, tool windows, overlapped, popup. it happens in all the cases.
Code: class CToolsDlg : public CBDialog { DECLARE_DYNAMIC(CToolsDlg) public: CToolsDlg(CWnd* pParent = NULL); // standard constructor virtual ~CToolsDlg(); CToolTipCtrl m_ToolsTips;
I have a dialog box with several edit control boxes and I want to identify the edit control when I click the left mouse button on it. Any button action (up or down) doesn;t register when the mouse is clicked on any of the edit controls. There has got to be a simple way to do this.
I have a thread with a while(1) loop in it. When the user push the stop button I would like that thread to end.
I thought about creating a bool and checking its value periodically in the thread and when I push the stop button I change the value of the bool for that the thread breaks out of the loop and finishes.

When my program is working with a big list, it always connects to the internet and checks information from a website. It is going fast, but when I'm trying to update a label on every connection, it just shows at the end, when everything is checked. Progressbar value is updating. How to solve this?

In my WPF application I created a LINQ to SQL entities class. Then I created a partial class and there add code to my entity class. Below is the code of it:
Then I executed LINQ to SQL. Works perfectly well. Then I bound WPF Datagrid radiobutton column to is_selected property of the partial class. Below is XAML code:
And here I have the problem. When I'm changing the radiobutton status from Unchecked to Checked it doesn't change the value of is_selected property from false to true in the partial class. I don't know why.

I created a program to display time continuously so it auto updates every sec but the issue is i cant integrate the code in the main program because to make time update continuously it needs a loop a infinite loop so none of the rest program gets to work. My q is : is it possible to display time continuously and make the rest of program continue normally? like a multi thread program because i want to display time every sec in the bottom of program. By the way this is console app not gui
The situation is , I have a ball which should move on a flat horizontal surface which i have created in a display of 800 x 400 . Right now!I am able to make it move left or right in direction using key inputs at a fixed speed.
But I want to make it move horizontally at a constant velocity without using keys. Like in copter game.
It should be able to move automatically , towards the right side.
Increment x position by speed variable does the trick but When I used it with keys I used to limit the movement like.
ball.x += ball.speed; if(ball.x > 750) ball.x = 750; // because my screen width is 800.
[URL] .... < this video will show what I really want to do with the ball
If you saw the game video in the link i gave, the ball kept moving with constant velocity. But it never went out of bound. What is keeping it from not getting out of display screen. Instead! its moving continuously... but stays almost at the center of screen. How?
This code works, but not fully This code reads com ports, when a string is available, I check to see if it contains some keywords defined in array If it does, i print out the string itself.
The problem i am having is that it seems to stop processing the data at some point but I do know that there are more strings to be read. So, it does keep reading more lines of data
