is there a difference when creating a graphic user interface dragging and dropping controls in the form and coding on source code, difference in a sense that the code will appear differently if the control is dragged then the code appears automatically on the source code as compared to typing it on source code?

View 1 Replies View Relatedi have developed an application in which i have icons in left side pane of application which can be dragged and dropped in client screen. Application is working fine with all the resolution except 1920x1080.
when setting the resolution to 1920x1080 while dragging icons to client area, icon is not attach to mouse pointer. instead there is a gap between the mouse pointer and the icon. i wrote code to identify the screen resolution but it does not seem to recognize 1920x1080 resolution. below code is giving incorrect resolution for 1920x1080 setting.
RECT actualDesktop;
GetClientRect(GetDesktopWindow(),&actualDesktop);
value of 'actualDesktop' variable is {top=0 bottom=783 left=0 right=1536} which is incorrect. according to current resolution size value should be {top=0 bottom=1080 left=0 right=1920}. Due to this, all the icons while dragging are adjusting according to incorrect resolution setting.
how to identify the issue and if there is any limitation with respect to screen resolution in VC++ 6.0 with windows 8 environment.
I am getting same issue when compiling in VS2012 in windows 8. Code does not seem to recognize 1920x1080 resolution setting and downgrading my application look and feel by setting it to lower resolution.
I am trying to modify a user control while modifying the main form. For example i have my main form open in one visual c# window and my user controls in another. However it seems that in order for my code changes in my user control to have any effect on the main form i need to close all my c# windows and then re-open them and even then that sometimes doesn't work am i doing anything wrong or is this supposed to happen??
Also yes i am saving and clicking build solution on my user controls.
I created a simple calculator in Win App. When I played it, the form is displayed blank. Not a single control is shown.
The only thing I've done differently is adding a Coded UI Test in my test project. This is the first time I'm going to try to add a coded UI test so I wonder if that's the cause for this.
I made one application in Visual Studio 2008. The main form is maximized, and contains many panels with different controls (like buttons, listboxes, etc,). All the controls have the dock option fixed as true in panels, and the panels occupied the whole area of form.
Now, when I try to run this application in a machine, with different resolution of the screen, the form is maximized (naturally), but the panels are not resizing, so the form has many null area. How can I resize the panel so, that they fill the whole form area?
I have a form with a picturebox and some buttons to move the picturebox. I don't want the user to guide the picturebox out of the form even by dragging the form border picturebox moves just in the form border, and also there is a button to guide the picturebox to the start position (start choose by user). What can i do?

View 4 Replies View RelatedI'm trying to write a program that takes input from the user (thats a char) and outputs it to the monitor in hex form.The program is meant to continuously take input from the user then output to the monitor in hex form until an EOF is detected this triggers the program to close.The following code does this except that I get a lower case 'a' at the end of each output.I think the 'a' has to do with the enter key and if that is the case how can i tell the program to ignore this input from the user.
Example: input from user: ABC output to monitor: 41 42 43 a
Code:
#include <stdio.h>
int main(void) {
char myChar;
while(EOF != (myChar = getchar())) {
printf("%x ",myChar);
}
system("pause");
return 0;
}
My program was to allow the user to enter a value as a C string in the form: xxx,xxx,xxx,xxx,xxx.xx, where x can be any digit. Well, so far here is my attempt. I think the question is, would I have to implement a switch statement for the digits, the comma, and the decimal, so that when a user inputs, let say 52,000.00 the switch statements would read the 1st digit, checks for decimals/commas and if not, proceed to read 2nd digit, and repeat?
Code:
#include <iostream>
#include <string>
int main() {
using namespace std;
char buffer[256];
char tempBuff[256] = {'

Figure this out using [TURBO C]
Create a program that will let the user input an amount in the form (367). The Program should determine the no. of coins for each dominations : 50,25,10,5,1. (using Turbo C)
What I want is just to make a validation of the users and passwords already set within my array and go to the other form. By the way this form I already made it my start up form on program.cs with the same command I am trying to back to MainForm.
void Button1Click(object sender, EventArgs e) {
string error = "denied";
string[,] usrpass = {{"User1", "pass1"}, {"User2", "pass2"}, {"User3", "pass3"}, {"User4", "pass4"},

I am drawing two circle (inner circle and outer circle) using DrawElipse method. I have created two pen object named OuterPen and InnerPen and creating Outer Circle using OuterPen and Inner Circle using InnerPen. Problem that I am facing is that when I increase the size of outer pen lets say 10px then it overlaps the inner circle and inner circle is hide. How can I increase the size of OuterPen outwards and not inwards so that it don't overlap the inner circle?

Extra info:
getrowsize() gives the size of a row in bytes (see VGA CRTC register).
getVRAMMemAddrSize() gives the size of a pixel in memory (1=byte,2=word,4=dword)
set/getBitPlaneBit(startaddr,plane,offset,bit[,on when writing]) sets/gets a bit on a specific bit plane offset (start addr is the start address register from VGA,
plane is the plane to read/write,
offset is the offset within the plane,

View 4 Replies View RelatedBasically I have a text file called words. I'm supposed to extract a word randomly form the file and have the user guess the word. If they guess the word correctly in x number of tries they will receive the definition.

This is more of a Application Design question, Let's say I have Form1(Login), this is opened from Program.cs, when the user enters details, the Event Handler makes a instance of a class, adds the data and stores the instance within Program.cs class.
So the best thing to do here, is to close the Form1(Login) and open Form2(Main) via Program.cs so that I can send the List<Login> object with my Login instance objects to said form. This form will remain open throughout the applications use as it's like the main GUI for all the programs functions.
When I close this form, I may want to save some information before the application is terminated, so I may as well store the Login instances in Program.cs anyway.
Main stepping stone: Multiple (usually around 3 max) users can login this system if need be, which will mean closing Form2(Main) and then opening Form1(Login) so that once Form1 is closed it can recreate the From2(Main) form and pass the new List<Login> to that form.
What's the best way to do this, at the moment i'm creating the Form2 instance like so:
//....
//Detect the Login form being closed
loginForm.Closed += new EventHandler(OnLoginClosed);
//...
//Open the main form when the login is closed
private void OnLoginClosed(object sender, EventArgs e)
[Code] .....
This seems like it will work and do the job, but is there a better and cleaner way? The List<Login> will be passed to Forms which are created via Form2(Main) as this information will be needed. It's just that ive been told not to use Forms for too much data containment.
I have researched quite extensively, experimented, and still cannot seem to change the properties of a control on an active winform from a user control.
So I have a user control which populates each dynamically added tab page in a tab control.
I have a textbox in the user control which I would like to type in, capture the text_change event, and change the text of the label in the winform.
I have a form with 2 text boxes (Email and Password)
The user fills in the text boxes and clicks on the Log in button. The code behind the log in button does the following, First connects to a table (Users) in phpmyadmin. Next runs a SQL query (SELECT * FROM `users` WHERE Email = '" + sEmail + "' AND Password = '" + sPassword + "'") sEmail being the variable created from the text entered in Email text box and the same for password.
Next if the record count == to 1 it opens up the main menu form and if the record count == 0 it fails and the user does not get to the main menu.
All of the above is fine and working however what I want to do is take over a variable from the log in form to the other forms.
The code is below for the sign in button as all my code is behind that (I think this may be where I'm going wrong).
public partial class WelcomeForm : Form{
public static string connStr = "server = localhost; " +
"database = ppw5; " +
"uid = James; " +
"pwd = buster;";
[Code] .....
And the Main menu form where I'd like to take a variable over with me, lets assume the variable is the UserID from the database table that I pull from the dTable I created.
public partial class MenuForm : Form {
//Call the CloseProgram class and create a new method called ClassClose.
CloseProgram ClassClose = new CloseProgram();
WelcomeForm User = new WelcomeForm();
public MenuForm() {
InitializeComponent();

I have a program which when a button is clicked on Form1 it runs a vision system operation on an image in a window on a Form1. There are also other buttons on the Form1 which can change things like threshold levels so the inspection can be run again with different settings. It all works fine but I want to change it to remove the buttons from Form1 so that when the user clicks on a button on Form1 it opens up another form, Form2, and all the buttons which were on Form1 are now on Form2 and the image analysis should run on Form1 when the buttons are used on Form2. I have taken over all the code from Form1 to Form2 and I'm trying to make this happen by creating a new oject on Form1 which calls a method on Form2 which contains the code which was in Form1 and called when the button was clicked on Form1 - not working!! I have a constructor in Form2 but I think I have become monumentally confused.
This was the code which was on Form1 when the inspection button was clicked.
private void cmdInspectOnce_Click(object sender, EventArgs e)
{
iReturn = VisionSystem.InvModeSet(IpeEngCtrlLib.I_MODE.I_EXE_MODE_ONCE);
if (_imgEngines!=null && _imgEngines[0]!=null)
_imgEngines[0].cmdInspectOnce();//InvModeSet(IpeEngCtrlLib.I_MODE.I_EXE_MODE_ONCE);
}
