I have a mobile application for android coded in javascript and a windows form coded in c#. I want my mobile app to send some data to the c# program. It is fine if the transmission is not secure. I searched the net. I found a site called pastebin.com. Unfortunately it provides api for posting and reading data. However I want something, where I can store,read as well as EDIT the data.
View 7 Replies View RelatedSo I have my GUI far along enough to start incorporating my program, but I am hesitant to start because I want to be careful to do it in an effective and easy to manage way.
The code so far for the GUI alone is about 2100 lines, and I estimate it will be about 8000-10000 lines long when the program is complete. The code for the actual program (without GUI), is about 6000 lines long so far, and will probably get up to about 10,000 when I've added most of what I intend.
Is it a good idea to have the GUI portion, or at least some of it in a separate source file? If you were to do this, how would you? Obviously you can only have one main function. Would you have a file just for the main function, a header file with all the necessary includes and global variables, and put different portions of the rest in separate files.
Concerning the GUI; In my main function, if you click a button, a function connected to that button is called. Inside that function, I may have code to hide many other buttons while this button is selected; Also to manage effects which see visually which button is selected. My program so far has like 70 different GUI objects which all get modified, hidden, shown, etc in different circumstances, and multiple menus.
My question; what's the most reasonable way to do this? Right now all my buttons, and their associated objects are all global. Is this reasonable? Is there an exception to the globals are bad rule in cases like this?
I need to create a client and server program. The client will have a GUI that will display all the available servers (since more than one will be running) in a list box.
I’m guessing a TCP connection will be the best method here, but how will the client find the servers to connect to? I won’t know the IP address of the server because anyone could take the server program and run it on their computer and the client would have to find it.
Is there some way to make the server send some kind of signal that only the client application will be to connect to? So the server will be sending out a signal, the client finds the signal and connects to the server. Is this possible?
i also need to be able to store the IP address the client selects so when the client application is run again it will automatically connect to the server that was stored.

I'm trying to connect to a SQL Server Database, but when I click my button1 my entire form just locks up and nothing happens! I have to click the "Stop" button to stop the form from running in Visual Studio! I'd at least expect to receive an error if some of the connection string was wrong.

i need to change the text in multiple ComboBoxs. i could do it one by one, but i have about 11 i need to change. i feel like doing it one at a time is not efficient. i was wondering if i can put the comboboxs into an array so i can use a for loop to change them all with out writeing it out 11 times.
View 9 Replies View RelatedI am creating one c# project. In this project I have one mdi form and many child forms.
All the child forms contains one panel named as panel1.
Now when child form opens i use the following code in all child form all child forms' load event contains the following line.
this.WindowState = FormWindowState.Maximized;
and all child forms' resize event contains the following line.
panel1.Left = (this.ClientSize.Width - panel1.Width) / 2;
panel1.Top = (this.ClientSize.Height - panel1.Height) / 2;
so my question is if possible that the above code i write only once so i donot write this code in all the child forms load and resize event.
I am writing a application that receives Event messages from a network device the problem I have is that the device sends some message 5 times per tiggered event on two of the events I like to use the rest of the messages are fine I need to create code to filter out the other 4 last messages that get displayed in a textbox the 5 message are identical I have added a timestamp to the sting and noted they are always 1 second apart so the format would be somthing like this:
11:23:01 - x - y
11:23:02 - x - y
11:23:03 - x - y
11:23:04 - x - y
11:23:05 - x - y
What I would like to do something like this, always append the first message to the textbox but ignore or even change the 4 messages that follow 1 second apart from each other that contain - x - y if any other message appears it should still append the text box as well
so the result i would like for the 5 event message as above should end like this:
11:23:01 - x - y
11:23:02 - custome message / ingnore append to textbox
11:23:03 - custome message / ingnore append to textbox
11:23:04 - custome message / ingnore append to textbox
11:23:05 - custome message / ingnore append to textbox
I want to update a label from Form2. When I click on the button on Form 2, the textbox on Form2 should update the label on Form1 and take me to a certain website. What ever URL is typed into the textbox on Form2 is what website URL the label on Form1 will take me to. The label on Form1 can say something such as You can check out my website here!!! and when they click on the saying it takes me to their website.

I'm still at the very beginning of learning WPF and there are still countless things i don't fully understand. For instance, as I can see in my WPF project, there isn't an event that would fire when the Background property of some control is changed. Or am I just missing it? If i'm not blind after all, and it really doesn't exist, is there any way i could get notified when the Background color of some control is changed?

View 5 Replies View Related In my MainWindow I have a UserControl called CamAccessLevel1. This will be one of a few different UserControls which will have more and more functionality to a device as the Level goes up.
Each of those functionalities are themselves a UserControl, so that I don't have to keep remaking them for each different "Level" that I make.
So... I have a UserControl in a UserControl in my Mainwindow. My first goal is to have a button in one of those sections send an event back to the MainWindow to close the application. This sections is called "ProgramControl", as it has functions that relate to the program itself.

What I have now is a producer-consumer model where producer sends a number "88" to consumer at random intervals. Now, I need consumer to send a number "99" back to producer at a random intervals, this probably should be done in a separate thread.

I am trying to do a LINQ Query by Double Clicking the child node. When I click on the parent node it brings up the correct data. But when I click on the child node it still brings up the data from the parent node. How do I get the child node to display the correct data?
I was using the same item click event on another listview, and it worked perfectly... I don't know why this is happening, but here's my problem:
When I double click on an item, and try to obtain its index in the listview, the items index always comes back as -1... Obviously -1 isn't an index, and I'm guessing that it is returning -1 because that item does not exist on the listview, but from what I'm seeing, it is impossible for the item not to be inside of the listview...
Here is the xaml for my listview:
<ListView x:Name="lstBookmarks" HorizontalAlignment="Left" Height="250" Margin="10,10,0,0" VerticalAlignment="Top" Width="327" ItemsSource="{Binding Bookmarks}">
<ListView.View>
[Code]....
When I uncomment the MessageBox, it shows -1... This is obviously not right lol. I have the same exact click event in another class, and I obtain the items index the same exact way.. The only difference between this listview and that one is that this listview is databound.. Is that the issue? If so, how does one overcome it?
I have a application that has a tab control and I change the font and color on form load.

I'm trying to create a program which can pan by keep clicking and move the mouse
1. First, I create a class that inherited from the UserControl Class
public partial class CanvasCtrl : UserControl
protected void OnMiddleMouseDown(object sender, MouseEventArgs e) {
if (e.Button == MouseButtons.Middle) {
[Code] ....
2, Second, I create the void in that class too, and write the code to get it to catch the event
public void MainMouseAction() {
this.MouseClick += new MouseEventHandler(OnMiddleMouseDown);
}
It not work, how to solve this out ?
I have successfully compiled a code where I created an array of buttons. I have added a click event to it like this :
Code:
buttons[indexofhashis2]->Click += gcnew System::EventHandler(this, &Execute::GOBUT_Click);
I have a standard event like this
Code:
private: System::Void GOBUT_Click(System::Object^ sender, System::EventArgs^ e) {
int x;
x = sender->Location.X;
}
Returns error saying Location is not a member of Object^.
I'm trying to create an array of button (user/runtime created buttons) and get different interpretations of the click event depending of wich button is clicked.
For example, if we create buttons[0] I wish to get the 0 or something relevant into the GOBUT_Click event.
