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'm trying to make colors transparent in c++ using a 3rd party library. I've successful made my background transparent but I feel I'm cheating by not understanding how I entered the value.
"0xff, 0xff, 0xff" is the color white but i'm not sure how it's the color white like with RGB values.

My question is mainly about networks. I wan to implement a simple transparent proxy in C, which will filter the browsed sites according to URL blacklist (check before sending the HTTP request) and keywords in content (check the <meta> in the HTML that was responded).
How can I do this? Listen in a local socket (ex. 8080), set the proxy in my browser and according to the requests that the browser sends to me open a socket with the server, forward the browser's request to the server and forward the server's response to the browser? (Of course by applying filters in the stages where needed.

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?

I 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.
Right now i am just making a super string with all of the selected values but eventually i am going to want to make a receipt with a checkout page.

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?

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 developing a project that generates questions from a database, the questions are generated with multiple choice answers. On this form I have got a textbox that reds the question from the database and 4 radio buttons that reads the possible answers from the database. The radio buttons text names are updated with records from a database table each time the "next button" is clicked.
What I want this program to do is that when the user selects one of the radio buttons, I want the system to check if the selected radio button textname equals the right answer in the database table. for example in the table there are 5 columns namely: option1, option2, option3, option4 and rightAnswer. So whenever a user selects a radio button, I would like the system to check if the selected radio button's textname equals the record in the "RightAnswer" column and if so I would a messagebox to show "correct" and if not the messgaebox to show "wrong"
This is the the way I am updating the radio button text names from the database This method is called when the form is loaded
void LoadingPossibleAnswers() {
Query = "SELECT * FROM AnswersTbl";
theReader = conn.ExecuteStatement(Query);
while (theReader.Read()) {
radioButton1.Text = theReader["Option1"].ToString();
[code]....
This method is called when the button is clicked
void CorrectAnswer( RadioButton rdb) {
string correct = rdb.Text;
Query = "SELECT * FROM FROM AnswersTbl;"
theReader = conn.ExecuteStatement(Query);
while (theReader.Read())
[code]....
When ever I run my code above, else condition executes even if the correct radio button is selected.

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...
Here is the code if needed:
XAML:
<Window x:Class="ClockApp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Name="MyWindow"
Title="Alarm Clock App" Height="180" Width="360" Visibility="Visible" ResizeMode="NoResize" WindowStyle="ToolWindow">

Basically, the program is just sort of a soundboard. The way it is now, it just reads all the names of the files in a particular folder (all .wav files), and then adds an entry to a listBox for each file found. What I would like to do, is instead of a listBox, have buttons for each one. Is there any way to iterate through a list of items and create a button for each one? The main problem I see is placing the buttons. It would have to have some sort of grid to place them in I would imagine...
