When dataset is written into the memory stream using the writexml method of dataset, the Declaration line of the XML document is missing. Dataset. writexml (memorystream, xmlwritemode. writeschema). After writing, memorystream does not contain the declaration part of the first line of the XML document. Solution: Write the Declaration line in memorystream. Samp

Sometimes we often encounter in the actual classification data mining, the class sample is very uneven, the direct use of this unbalanced data will affect the classification of some models, such as the logistic REGRESSION,SVM, a solution is to balance the data sampling, here provides a recommended code implementation , the input and output data formats are required as label+tab+features, such as LIBSVM formatUsage:Usage: {0} [options] DataSet Subclass

Export dataset to excel and dataset to excel I found a lot of such code on the Internet. If it weren't for Chinese garbled characters, it would be too complicated. This is the best one I have ever used. // Ds is the data source, filename is the saved file name publicvoidCreateExcel (DataSet ds, stringFileName) {// sets the information HttpContext. current. resp

Use some DataSet functions to log on to the website, and use dataset to log on to the website. First, I have to complete registration and store my personal information in the database. Secondly, some objects in this section are stored in some documents and need to reference namespaces.

With the popularization of ADSL Broadband, many domestic users have entered the Internet era. However, we gradually feel that the speed of K is not fast enough. It would be better if it is faster. When installing broadband, China Telecom's staff will tell you that there are still 1 m and 2 m broadband options, but the cost is very expensive and there is no way to do it. Let's just wait for K.China Telecom's rapid promotion of starsBut now it is different. China

At present, China's ISP mainly telecommunications and netcom two, telecommunications and netcom between the low bandwidth, which led to a lot of problems, the problem of corporate information communications have an impact. The country has a lot of branches of logistics/distribution companies, due to the difference between the southern and northern ISPs, resulting in North users to visit the southern branch of the Web site, the speed is very slow, unable to exchange data. At the same time, becaus

At present, the router industry is developing at a high speed. At this stage, the routing technology is very mature. Next we will mainly explain how to use dual-WAN Port Routers to achieve communication between China Netcom and China Telecom. Currently, China's ISP service providers mainly include China Telecom and China Netcom. The bandwidth between China Telecom
