In the previous blog post, I mainly described how to get and set the system's default printer, this article will describe how to monitor the status of the printer in real-time, recording the printed documents, the number of copies printed, as well as the printing time and other printing information.1. Printer Collapse Machine TechnologyBefore we formally introduc

One: On a computer with a printer, share the printer 1, first of all, to confirm with the shared printer connected to the Power-on state, and has installed the printer driver, and can achieve normal printing, for the driver installation is not described here. (The actual operation of the two computers are the Windows

API print function abortdoc cancel printing a document abortprinter delete a buffer file associated with a printer addform adds a new form addjob to the printer form list for obtaining a valid path name, this allows you to create a background print file for a job. It will also assign a job number for the job addmonitor to add a printer monitor addport for the

The following are some methods for sharing printers between different subnets (network segments:First (experiment passed ): This method allows two users in different subnets to share a printer. If possible, they can even share a printer over the Internet. 1. Set a firewall for the machine on which the printer is installed-except --> file and

Microsoft GDI + image vulnerability details What is GDI +:GDI + is a graphical device interface that provides two-dimensional vector graphics, images, and la s for applications and programmers. Vulnerability impact:The GDI + Library (GdiPlus. dll) used in Microsoft products provides access to various graphical methods

C # using GDI + When our software needs a variety of pie charts and histograms to represent data, we might think of using graphical controls in offices or third-party controls, but now most third-party controls need to be registered, and some free controls will have developer tags. For graphical controls that use offices, they are not very well controlled in the program and are less easy to use, so here I give you a way to use

The simplest understanding of GDI + is used to draw. These include points, lines, rectangles, strings, and so on.Let's start with an example that shows how to draw a line in the WinForm form, and the line doesn't disappear as the form moves.usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;namespacegdidemo{ Public Partial classForm1:fo

Coordinate System in Windows GDI (2) By leezy_2000 1. How is the coordinate of the Logical space converted into the coordinate of the device space? Let's clarify how the logical coordinate space is converted. The transformation from the world coordinate space to the page coordinate space (two-dimensional affine(Note 3)Conversion ): Various transformations involved in this process, such as equality, translation, scaling, image, rotation

This article introduces an example of using the C language version of GDI + to create a watermark image. The following is the program code: # Include ".. /.. /samplecode/comcode/application. H " Steps for making a watermark image in this example: 1. Open the original image and the original watermark image; 2. Create a new image, that is, the watermark image to be made, which is the same size as the original image; 3. Draw the original image to the new

Regardless of the language used, anyone who has used Windows's GDI + is familiar with colormatrix, And I have mentioned many times in my blog articles, I also gave a detailed explanation of the functions of the colormatrix in the article "GDI + for VCL basics-Color adjustment matrix colormatrix". Although I think that I am quite familiar with colormatrix, however, I still know its principles, but I do not k

You can use Windows via C/C ++ to understand the kernel object and call closehandle after the kernel object is used up. This function is used to convert the usage count-1 of the kernel object. When the count is 0, the kernel object will change to the signal status/destroy. Kernel Object does not belong to the process and belongs to the Windows kernel. Process has only one kernel object handle table, which is used to store all kernel object handle. Therefore, multiple processes can use one ker

This article will demonstrate some basic usage of GDI + painting. First, let's do something evil and directly throw an exception in the onpaint event:Protected override void onpaint (painteventargs E) { Base. onpaint (E ); Throw new exception (); } To suppress the dialog box that prompts to throw an exception for processing, you can add the following line to the main function:Application. threadexception + = (S, e) => {}; In this way, we will get a re

1. download the gdiplus file (GDI + for vc6.0 SDK) and copy the files in the uplodes and Lib files to the uplodes and Lib folders in the VC directory. place the DLL file in system32. if it already exists, you do not need to replace it. : Http://www.codeguru.com/code/legacy/gdi/GDIPlus.zip 2. Complete the initialization in the project where you are going to use GDI
