In a managed C ++ project, we can use the "Using namespace" expression to include managed types. just like using "# include" incorrectly will cause some compile error, declaring "Using namespace" globally will cause some problems too. we encountered "ambiguous symbol" error when integrating ASM 4100. to resolve the issue, we can make the "using namespace" impact locally.
For example. The following code may have "ambiguous symbols" error:

Due to the project needs, the WES7 system needs to be customized, delete all Windows words basically no problem, mainly encountered the following 3 issues:1. The camera does not work properly under the application template, even if the driver is installed;2. Jabra speakers are not available;3. Unlimited hotspot (SoftAP) cannot be opened with a command (Netsh xxxxxxxx)?? Problem solving:1. The camera can not be used because of the lack of a build, but

DescriptionN cows numbered 1 to n are driving their cars to fly on the Nuedebia motorway. The motorway has M (1≤m≤n) lanes. Cow I has an own speed limit of Si (l≤si≤1,000,000). after a bad driving accident, the cows become very careful to avoid collisions. In each lane, if a cow I in front of a K cow drive, the cow I speed limit will drop k*d units, that is, her sp
unspoken rules (if there is no potential rules, you can imagine in the congested city center, all kinds of box trucks, cars, pedestrians, car, after all, there is no rub, you have to know the rearview mirror is a dead angle And drivers are not necessarily able to grasp their own car's length and width of the torque ...) The impact is always local, a small number of events, so it is worth the risk, but once a conflict, such as rubbing, accidents, etc., will cause a large area of congestion, whic
Calvin is driving his favorite vehicle on the 101 freeway. he notices that the check engine light of his vehicle is on, and he wants to service it immediately to avoid any risks. luckily, a service lane runs parallel to the highway. the length of the highway and the service lane is

NSegments of unit length, where each segment can have different widths.
Calvin can enter into and exit from any segment. Let's call the en

in LAN technology, the two words of conflict and broadcast domain have a great impact on network performance, let's take a look at how these two words affect network performance. 1. The conflict zone of LAN technologyif you want to drive off the freeway, but every time you try, there is a car blocking your way. If forced out, collisions occur, similar to what happens on an Ethernet network using a carrier-listening multi-access (CSMA/CD) protocol with

1. Partition of the hard diskIn Linux we know a very important concept, that is, "Everything is file", where everything represents all the objects in the Linux system, naturally also includes the hard disk device in Linux. All the devices in Linux are abstracted into one file and stored in the/dev directory.The hard drive device name in the Linux system is typically hd[a-z] or sd[a-z] (A-Z is the partition number), such as Hda,hdb,sda,sdbSo what's the difference between this different device nam

One solution to the network congestion: Wi-Fi is becoming overcrowded on the freeway. At present, the world's fastest Wi-Fi transmission speed of only 300Mbps (a few can reach 600Mbps), equivalent to only about 36MB per second transmission of content. It's not a problem when people use it to look at websites and mail. But today, with more and more complex usage requirements, old technical standards have become stretched. 5G Wi-Fi is abou
For the concept of bandwidth, a comparison of the image of an analogy is the freeway. The amount of data that can be transmitted on the line in a unit of time, the common unit is bps (bit per second).
So, how do you modify its values?
1, point "start"--point "run"--enter "gpedit.msc" (note, the input is not "", the transmission gpedit.msc), and then click "OK" (or enter), will open the system of "Group Policy"

Some netizen message asks a question: Why installs the operating system to be unable to surf the net. My answer is: the normal Internet access depends on three: 1. There is no problem with the NIC and its driver; 2. There is no problem with the system network connection settings; 3. There is no problem with the network provider "Freeway". For the specific analysis of network failure and find, you can use the "command Prompt" (in the "Run" into the cmd
