Delphi provides powerful DBGrid components to facilitate database application design. However, if we only use the DBGrid component, each grid is a simple text editing box, which is inconvenient for users to input data. Delphi also provides some other data components to facilitate user input, such as dbcombobox and dbcheckbox, but these components do not have the powerful functions of DBGrid. Can

Today, I tried it .. something about delphi .. because you do not like to install and kill software .. because I still like high system efficiency... there is only 360 on the computer. usually look at your own port .. generally, it's okay. Today, when I compiled the software and went to the Virtual Machine for testing, how was it a virus? I saw the prompt of Kingsoft, and Delphi's nightmare was depressing (I often walked by the river and wet my shoes

There are several versions in the middle of Delphi 7 and Xe, which are not very popular. First, Delphi is somewhat marginalized, and second, 7 is almost perfect in the XP environment. There are fewer and fewer books on delphi on the market, and it is useless to provide information from 7 to Xe. Here I will try to list the differences and precautions between 7 and

I have known a value assignment instruction (mov) of an Assembly and an addition instruction (ADD), so I can give an example. For example: Add ax, BX; this is equivalent to ax: = AX + bx in Delphi; In addition, a list is provided in advance-Delphi can use assembler to manage the following registers:32-bit register: eax EBX ECx edX ESP EBP ESI EDI16-bit register: ax bx cx dx sp bp Si Di8-bit register:

Principle: Put the exe that needs to be included into the input source file, compile it with the original program into an exe file, release the exe when the program runs for the first time, and then call the exe file. Steps: 1. Create an rc file. It can be written in any text editor. File Format: "Resource Name resource type file name ". For the resource type, if it is an exe file, it should be an EXEFILE, and if it is a binary file, it is RCDATA. Create a file float. rc: Code Code highlighting

Use the MDI form in Delphi. The project file is as follows: Application. initialize;Application. createform (tmainform, mainform );Application. createform (taboutbox, aboutbox );Aboutbox. show;Aboutbox.

, drag the last edit and a label, a button, press F9, lean, and do not start the browser and display the page. Not after setting browser in Tools-gt;options. Don't know what the reason.

Say "basic" means that the page does not appear, but automatically opened IE, only the above shows the server error prompts. may be related to the environment of the respective machine. My machine is fitted with oracle,

Since the initial value of the dynamic array in Delphi is not always 0, setlength is used before each use of a one-dimensional array, and then fillchar is generally used for clearing, however, if the array is more than dozens of MB, the efficiency of fillchar is very low. For this reason, I specifically wrote some optimization code for clearing the array or memory. Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlig
