Many Windows API functions do not return values to express error messages. Instead, they allow callers to Use API getlasterror () to obtain error codes. When debugging the program, we can see that the API function call failed. We want to see the getlasterror () error code to see why the failure occurred. We can use the windbg command.! GLE Example: 0: 000>! GLELasterrorvalue: (win32) 0 (0)-the operation completed successfully.Laststatusvalue:

Last month, acnchen, Business Development Manager of Bing (Bing Maps) Greater China, published an article titled loading other Maps (Google satellite Maps, etc.) in the Bing map SilverLight control, it details how to load Google satellite maps. This article is similar to this article. In addition to Google satellite

As described in the first article of this series, developing Bing Maps based on Silverlight requires a development Key in addition to the development environment. What is this Key used? The Silverlight control is an essential parameter for map rendering. It can be understood as Microsoft Bing Maps, which is an authorization Development Key activated by users, this article attempts to use a simple example dr

A few days ago, the project used network maps, mainly Baidu maps and search maps, or sogou maps and Google Maps. The search scope is mainly in Beijing urban areas, and a bit is used in the suburbs. The advantages and disadvantages are summarized as follows: 1. Google

surface details of the polygon facing the screen are enhanced, rather than the whole model. Therefore, the performance cost is not as high as that of direct upper mode. In comparison, the displacement Paster has no flaws in the effect, but it does not have any disadvantages. First, hardware requirements are high. shadermode3.0 must be supported, because Sm3 can be used for texture operations at the vertex stage. At the same time, mosaic consumes a lot of performance. However, in terms of GPU pr

future dx10 uniform rendering architecture. Compared with all the concave and convex pasters we have introduced, displacement pasters are the only way to change the geometric shape of a polygon surface. Compared with the light tracing algorithm to be introduced later, the performance consumption of this algorithm is not dominant, but it is actually more reasonable. It gives the screen more special effects. What's more interesting is that it does not conflict with other pixel-based concave and c

The function navigation provided by Bing Maps Silverlight Control is very powerful. In terms of design, it provides great support for extensions and provides commands and buttons that can be extended and directly used by many users, if you are not clear, you can view the article "Custom navigation bar" that I wrote earlier. However, compared with the functional navigation menu provided in DeepEarth, the menu is not so bold and dynamic. I personally pr

As you know, Google Maps is more and more popular around the world. Is it possible to integrate Google Maps into my MapGuide Enterprise Fusion viewer as base map? Yes, it is! As MapGuide Fusion viewer uses a subset of OpenLayers, it allows us to access to the underlying OpenLayers API. in this article, we will show you how to integrate Google Maps into our exist

As follows: JavaScript code: New encapsulated version:VaR map; var geocoder = new Google. Maps. geocoder ();/***-25.363882, 131.044922 * initial map */ Function initialize (LAT1, lng1, zoom, canvas_div ){ VaR mylatlng = new Google.

Bing Maps Advanced Series Five: Deepearth minimap control for Bing Maps extended Mini Map The Bing Maps Silverlight control provides us with a simple and convenient development model, but there are a number of drawbacks, such as we want to implement a mini map feature, and there is no such built-in controls for Bing map Silverlight. But there's no need to bother

Basic Development of Baidu maps and Development of Baidu maps Due to the needs of the project, I recently encountered Baidu map Android development and encountered many problems. I believe many bloggers have encountered these problems. Now I will share my practical experience with you. To develop Baidu maps, Step 1: first log on to the Baidu map open platform and

Android sends real-time maps and Android real-time maps In most instant messaging, the sending location function is available. When sending a location, you should note that the items in the chat interface display real-time maps, such: How is this implemented? In fact, this is very simple. Every major map provider has a static map API. If you call this API to inp

Google maps has become an essential tool for home-based travel. Chrome extended select to get maps is useful when you book a hotel online or schedule a travel trip, after you select the address information on the webpage, as long as it is indeed an address (rather than any other text, this extension has its own recognition method, which must be 3-15 words, and contain numbers and words at the same time), a

If you have Google mobile Maps on your phone, you can find that as long as your mobile phone can connect GPRS, even if there is no GPS function, you can locate the location of your phone, but the accuracy is not accurate. Before we explore this principle, we need to know some mobile knowledge about what is Mnc/lac/cell ID.Mobile Network Code (MNC)Mobile network number, China Unicom CDMA System MNC 03, China Mobile is 00.Mobile Country Code (MCC)Mobile

The OSM (OpenStreetMap-Open Street Map) service is an implementation type that allows you to publish your own map data images, the motive behind the establishment of open street maps is to create and provide geographical information (like street maps) that can be freely used to everyone who wants to use them, just as free software gives users freedom, this article describes how to use the map service releas

This article mainly introduces the Web page embedded Baidu map and the use of Baidu Map API custom map Detailed stepsInsert Baidu Map in Web pageIf you want to add Baidu map on your own page, you can use the Baidu Map API. Use the following methods:The first step: Enter Baidu to create a map of the site http://api.map.baidu.com/lbsapi/creatmap/, search out the location you want to show, as shown.The second step: set the map, you can set the site to display the width of the map, the remaining opt

Geographic Encoding and anti-Geographic Encoding of iOS native maps, and Geographic Encoding of ios maps When we want to implement the function in the App: Enter the place name, encode it as the latitude and longitude, and implement the navigation function. Therefore, I need to use the Geographic Encoding function in the native map, and the Core Location mainly includes the Location and Geographic Encoding

At the same time, it integrates Baidu maps, positioning and navigation pits and maps. The project uses many map functions and integrates the functions of map, positioning, and navigation. Every single use is smooth, but it may be a problem when used together. Every time I integrate Baidu map, it will be in http://lbsyun.baidu.com/sdk/download?

During personal space project development, modules on the page can drag and drop their positions freely. The module named "" contains an instance of a Google map object. We use the API service provided by Google Maps V3. During the drag and drop operation on its container, in IE7, a bug occurs: the map block is overwritten by the background and background image of the parent body. This is because in the drag-and-drop event processing function, JS wil

I believe that most of the users who use Bing Maps for development have seen the following picture: when we develop Bing Maps, a prompt error occurs when the Development KEY is incorrect, resulting in user authorization verification failure. 　　　　　　　　 The disadvantage of using Bing Maps Silverlight Control is that it uses the online map data provided by Microsoft
