I have a submit button, where users are clicking after entering text into textboxes and (hopefully) check boxes (for yes/no).
Here is my code, and when I run it and press submit, there is no action. It just continues to loo.
string ConnectionString = @"Data Source=.SQLEXPRESS;
AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True";
using (SqlConnection dataConnection = new SqlConnection(ConnectionString)) {
using (SqlCommand dataCommand = dataConnection.CreateCommand())
[Code] .....
Note: I took out the Checkboxes in the code to hopefully get a successful run, to no avail.

I'm trying to create a dialog where some of the buttons have pictures on them, rather than plain text. I notice that under the button's properties, under the "styles" tab there's a checkbox "bitmap". I can't seem to find any easy way of setting a bitmap.

tell me the EASIEST way to create a button with an image on it.
I am not interested in using the owner draw property with CBitmapButton and then have to create a whole lot of bitmaps for all the different button states.
There must be a way to simply create an ordinary button which displays an image rather than or as well as a caption....?

I have created an application that has bunch of buttons on top and i want to change the image when I click on the button. But unfortunately I can't get it to work.
Here is the code:
if (serialPort1.IsOpen) {
tsbCommPortOpenClose.ToolTipText = "Open serial port";
closeCommPortToolStripMenuItem.Text = "Open serial port";
tsbCommPortOpenClose.Image = Image.FromFile("Red.bmp");
serialPort1.Close();
[Code] ....
The second one which changes the image to "image2" works fine. Here is the definition of image2:
namespace Regress;
...
private Bitmap image2;
System.Reflection.Assembly myAssembly = System.Reflection.Assembly.GetExecutingAssembly();
StreammyStream = myAssembly.GetManifestResourceStream("Regress.Sharing.gif");
image2 = new Bitmap(myStream);
When I do the same with the other image that I want to use, it won't work! I opened the project properties and added the image into the resources too, and it still doesn't work. It fails and says the file was not there. I've put a copy of the file in the root directory and one in "Resources" folder but it still doesn't work.

I am writing a GUI application with C++ Visual component Libraries and Win32API under windows OS.
As part of this app, I have to change color of the MS Windows button control depending on the external state.
I understood, Win32 will not support changing button control color directly as it will not support for this.
how to change the button color?

I have subclassed CFileDialog. I need to select both file and folder on certain case only. Suppose I have a folder selected and it is containing desired file type. Then in such situation, On clicking open button will not open the selected folder. But just close the CFileDialog with IDOK.
For doing this I need to provide my own implementation for Open button handler. I am not getting how I can do this.

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;
[Code] .....

I am writing an application that needs to temporarily disable the Play/Pause button that appears on multimedia keyboards.
Normally, a key can be blocked quite easily by installing a low level keyboard hook (WH_KEYBOARD_LL) where the KeyboardProc intercepts the key (in this case VK_MEDIA_PLAY_PAUSE) and returns a "1" instead of calling CallNextHookEx. I have tried this with other keys (including the Windows key VK_LWIN) and this works perfectly. I also have no problems with this method under Windows 7 where all keys, including VK_MEDIA_PLAY_PAUSE get blocked.
Windows 8 is a different story. When my application has input focus, everything works as expected, meaning the VK_MEDIA_PLAY_PAUSE key gets blocked and no other application responds to it. However, when my application loses focus, my hook procedure gets called (this was verified by sending out a OutputDebugString) but other applications respond to key even though I return a "1". As soon as my app gets focus again, everything is block as it should.
After some investigation, I found that the multimedia keys not only generate keystrokes but also generate WM_APPCOMMAND messages so I added ShellProc (WH_SHELL) hook with the following hook procedure:
LRESULT __declspec(dllexport)__stdcall CALLBACK ShellProc(int nCode,WPARAM wParam,LPARAM lParam) {
// Do we have to handle this message?
if (nCode == HSHELL_APPCOMMAND) {
OutputDebugStringX(">>>>> HSHELL_APPCOMMAND");
[code]....
This procedure is only getting called when my app has input focus. Whenever I have input focus and return "1" the Play/Pause command gets blocked. As soon as I lose focus the procedure does not get called/hooked.
As I have mentioned, the code works for other keys, just not the multimedia keys.
Alternatively, another way of blocking the multimedia keyboards Play/Pause button?

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.

I'm currently trying to work with more than one form, but I didn't succeed yet. What I need is quite simple: Once the program runs, a small form appears first asking "what would you like to do" with corresponding buttons for each option. Each button loads a new different form for a different task. So basically I need to open and close forms, also having two forms loaded at the same time (pop-up style) would be great for certain purposes.
I still haven't figured how to do it properly. I'm currently using VC++ 2008 and my project is a Windows Forms Application.

I have a slider control on a dialog box. I am playing a video file and slider moves according to the video elapsed. Suppose I have set the slider range to 100. Now till some point say 90, the slider moves to the point wherever I click the mouse. but at the last point in between some range say 90 - 100 (to the end of the slider), if I click the mouse button anywhere, slider jumps to the end.
I am using a TimeLine control where user can add more than 1 video (1, 2, 4, 8, 10 , 50 etc......), If I use only one video, slider moves as per the video progression.....Issue arises when I add more than 1 video and click on the start button, slider starts moving....Now when I drag the slider to any position or I click the mouse button anywhere on the slider control, slider thumb moves to that position and immediately jumps back to some other position. This is the Issue, I am facing.
share some sample code where slider is moving with the video showing the progress of the video.
I want to implement a functionality similar to VLC player. Wherever user clicks the mouse, slider moves to that point.

My code is below:
Total Interest ends up as my last Monthly Payment amount instead of adding up all Interest Paid - What am I doing wrong?
Total Paid isn't calculating correcly either - What am I doing wrong?
I suspect both are very similar problems. I've tried several different calculations, but cannot figure this out.
#include <iostream>
#include <cmath>
using namespace std;
double GetMonthlyIntrest (double OpenBalance,double rate);
bool ContinuePgm();
int main () {
double StartingBalance,rate,amount,OpenBalance,IntPmt,TotalInt=0.0,GrandTotal=0.0;

I have a CDHtmlDialog app in which am trying to add a CSS media query in the HTML file as shown below, but it doesn't work.
@media (max-width:20em) {
table, thead, tbody, tfoot, th, td, tr { display:block; }
tr + tr { margin-top:1em; }
}
The same CSS works fine if i open in a browser like IE, FireFox, Chrome. But inside the CDHtmlDialog app this doesn't work.
I am using Visual Studio 2012 for development and have IE 11 installed in my machine.

I keep having problems with CMFCPropertySheets. I now have it embedded in a resizable dialog and the property sheet and page gets resized when dialog is resized all that is working fine.
Problem is OnSize is being called when the dialog is being resized NOT when it has finished resizing so the values reported in cx and cy is the old size not the size AFTER resizing. What could be causing this? Isn't OnSize call AFTER the size has been changed and OnSizing called WHILE the size is being changed?
I have a list control that needs to take up full rect in each page and when the dialog is maximized it stays at previous size even though the sheet and page have both maximized as they should.
I ran a trace on the OnSize even for both the sheet and page and OnSize is being called during the sizing and not after it has already been sized like it is supposed to.
