Or is there a better place? So wndTopMost is often a poor choice. My code was working perfectly on my development PC, but, naturally, failed on the next machine I copied it to. After convincing myself that my own code mimicked the way the sample projects chatsrvr and chatter work I tested these examples on the problem machine and they failed in the same way.

MFC VC Socket Experts: CAsyncSocket OnReceive() never called

When the timer callback is called we use invalidateRect to invalidate the individual rects that need to be drawn. If it's not tell me and I'll repost to microsoft. I have written some code using CSocket, and now there's a requirement for a timeout when receiving data.

Thanks for any help! New so-called features in Outlook -- can they be defeated? Our office recently got "upgraded" to Outlook It has a couple of so-called "features" which I find incredibly annoying and impossible to defeat. I'd be interested if anyone has found a way, other than the ridiculous workarounds listed on Microsoft's website. The two features which annoy me most are: Displaying both the name and the email address in email message headers; Displaying two entries in the "Select Names" dialog box for everyone who has both a fax and an email address, that is, virtually everybody.

Resources are interface elements that provide information to the user. Bitmaps, icons, toolbars, and cursors are all resources. Some resources can be manipulated to perform an action such as selecting from a menu or entering data in dialog box. Most resources are created by selecting the desired one from the Add Resource dialog box. Identifiers An identifier is a symbol which is a constant integer whose name usually starts with ID.
Symbols provide a descriptive way of referring to resources and user-interface objects, both in your source code and while you're working with them in the resource editors. The name-plus-value definition is stored in the Resource. Continue by opening this file in editor and you will see the dialog box identifier and its integer value as well.
Icons An icon is a small picture used on a window which represents an application. It is used in two main scenarios.
On a Window's frame, it is displayed on the left side of the Window name on the title bar. If you look at our MFCModalDemo example, you will see that Visual studio was using a default icon for the title bar as shown in the following snapshot. You will see two icons. We will use the same icon. Menus Menus allow you to arrange commands in a logical and easy-to-find fashion. With the Menu editor, you can create and edit menus by working directly with a menu bar that closely resembles the one in your finished application.

Toolbars A toolbar is a Windows control that allows the user to perform some actions on a form by clicking a button instead of using a menu. A toolbar provides a convenient group of buttons that simplifies the user's job by bringing the most accessible actions as buttons.
A toolbar can bring such common actions closer to the user. Toolbars usually display under the main menu. They can be equipped with buttons but sometimes their buttons or some of their buttons have a caption. Toolbars can also be equipped with other types of controls. To create a toolbar, following are the steps. You will see the following screen. OnInitDialog as shown in the following code. It only does the calculations. You will see the following dialog box which also contains the toolbar.
Accelerators An access key is a letter that allows the user to perform a menu action faster by using the keyboard instead of the mouse. This is usually faster because the user would not need to position the mouse anywhere, which reduces the time it takes to perform the action. Run this application and press Alt. You will see that the first letter of all menu options are underlined. Shortcut Key A shortcut key is a key or a combination of keys used by advanced users to perform an action that would otherwise be done on a menu item.
Most shortcuts are a combination of the Ctrl key simultaneously pressed with a letter key. To create a shortcut, on the right side of the string that makes up a menu caption, rightclick on the menu item and select properties. Repeat the step for all menu options.
Accelerator Table An Accelerator Table is a list of items where each item of the table combines an identifier, a shortcut key, and a constant number that specifies the kind of accelerator key. Just like the other resources, an accelerator table can be created manually in a. Following are the steps to create an accelerator table. We will also add New menu item event handler to testing.

Re: CAsyncSocket OnReceive() never called
It is enclosed on a page with a tab on top. The tab names the page and indicates its purpose. Users click a tab in the property sheet to select a set of controls. To create property pages, let us look into a simple example by creating a dialog based MFC project. Once the project is created, we need to add some property pages. To implement its functionality, we need a property sheet. The Property Sheet groups the property pages together and keeps it as entity.
Defines the class behaviors for the application. Otherwise, any window creation will fail. This dialog box contains two property pages. It is used to arrange a group of GUI elements in your application. Sizes of the child elements. We will drag one Static Text and one Edit Control as shown in the following snapshot. Control Grid Control grid is the guiding grid dots, which can help in positioning of the controls you are adding at the time of designing.
To enable the control grid, you need to click the Toggle Grid button in the toolbar as shown in the following snapshot. Controls Resizing After you have added a control to a dialog box, it assumes either its default size or the size you drew it with. To help with the sizes of controls on the form or dialog box, Visual Studio provides a visual grid made of black points. To resize a control, that is, to give it a particular width or height, position the mouse on one of the handles and drag it in the desired direction.

Most of the time, these positions are not practical. You can move them around to any position of your choice. Then drag the selection to the desired location. Let us select the Static Texts and Edit Controls. To help with positioning the controls, Visual Studio provides the Dialog toolbar with the following buttons.
Tab Ordering The controls you add to a form or a dialog box are positioned in a sequence that follows the order they were added. When you add control s regardless of the section or area you place the new control, it is sequentially positioned at the end of the existing controls.
If you do not fix it, the user would have a hard time navigating the controls. The sequence of controls navigation is also known as the tab order. You can now see the order in which all these controls are added to this dialog box.
To Change the order or sequence of controls, click on all the controls in sequence in which you want to navigate. In this example, we will first click on the checkbox followed by Name and Address Edit controls. Then click OK and Cancel as shown in the following snapshot. Let us run this application and you will see the following output. MFC - Controls Management In MFC applications, after visually adding a control to your application, if you want to refer to it in your code, you can declare a variable based on, or associated with that control.
The MFC library allows you to declare two types of variables for some of the controls used in an application a value or a control variable. The other variable is known as Control Value Variable.
