怎么将文件从ENA复制到PC（VC ++）

我已经开始尝试使用：MMEM：TRAN和：MMEM：COPY但它似乎不起作用。
它看起来像这样：//测量viWrite（vi，（ViBuf）“：CALC1：PAR1：DEF S11  n”，20，＆amp; retcnt）;
//存储测量数据viWrite（vi，（ViBuf）“：MMEM：STOR：FDAT'ramtry.csv' n”，33，＆amp; retcnt）;
viWrite（vi，（ViBuf）“：MMEM：COPY'ramism.csv'，'C： ram1.csv' n”，38，＆amp; retcnt）;
/ *关闭会话* / viClose（vi）;
viClose（defaultRM）;



     以下为原文

  I have already gone ahead and tried using :MMEM:TRAN and :MMEM:COPY but it does not seem to work. It looks like this:

//Measurement 
viWrite(vi,(ViBuf)":CALC1:PAR1:DEF S11n",20, &retcnt);
//Storing measurement data
viWrite(vi,(ViBuf)":MMEM:STOR:FDAT 'ramtry.csv'n",33, &retcnt);

viWrite(vi, (ViBuf)":MMEM:COPY 'ramtry.csv','C:ram1.csv'n",38,&retcnt);
/* Close session */
viClose (vi);
viClose (defaultRM);

嗨，我有一个例子来转储图像文件并从PNA复制它，ENA的命令非常相似。
FileStream output = new FileStream（filePath，FileMode.Create）;
BinaryWriter writer = new BinaryWriter（output）;
string str6 = @“C： tmppnascreen.png”;
string str =“DISP：ANN：MESS：STAT OFF”;
ioDmm.WriteString（STR）;
str =“HCOP：FILE ”“+ str6 +”“”;
//从PNA转储图像，您应该更改代码以将数据文件保存到ENA ioDmm.WriteString（str）;
OPC（）;
str =“MMEM：TRAN？”“+ str6 +”“”;
ioDmm.WriteString（STR）;
string str5 = ioDmm.IO.ReadString（1）;
int count = Convert.ToInt32（ioDmm.IO.ReadString（1））;
int num2 = Convert.ToInt32（ioDmm.IO.ReadString（count））;
byte [] buffer = new byte [num2 + 1];
buffer =（byte []）ioDmm.IO.Read（num2）;
writer.Write（缓冲液）;
writer.Close（）;
output.Close（）;
str =“DISP：ANN：MESS：STAT ON”;
ioDmm.WriteString（STR）;

  Hi, I have an example to dump image file and copy it from the PNA, the command for ENA is very similar.

FileStream output = new FileStream(filePath, FileMode.Create);
            BinaryWriter writer = new BinaryWriter(output);
            string str6 = @"C:tmppnascreen.png";
            string str = "DISP:ANN:MESS:STAT OFF";
            ioDmm.WriteString(str);

            str = "HCOP:FILE "" + str6 + """; //dump image from PNA, you should change your code to save the data file to ENA
            ioDmm.WriteString(str);

            OPC();

            str = "MMEM:TRAN? "" + str6 + """;
            ioDmm.WriteString(str);

            string str5 = ioDmm.IO.ReadString(1);
            int count = Convert.ToInt32(ioDmm.IO.ReadString(1));
            int num2 = Convert.ToInt32(ioDmm.IO.ReadString(count));
            byte[] buffer = new byte[num2 + 1];
            buffer = (byte[])ioDmm.IO.Read(num2);
            writer.Write(buffer);
            writer.Close();
            output.Close();
            str = "DISP:ANN:MESS:STAT ON";
            ioDmm.WriteString(str);

Hi Ningchen,

Thank you for the help. When I run your code what changes do I probably have to make because it says the following errors. Is there like a separate function named 'Filestream' and 'Binarywriter' that you wrote which it is referrring to? If so can you add that as well? Thanks in advance.

Cheers
Ram

嗨，代码在C＃中。
您可以在C＃控制台应用程序中尝试它。
之后您可能需要将其转换为C ++。



     以下为原文

  Hi, the code is in C#. You can try it in C# console application. You may need to translate it to C++ after that.

我不擅长C ++，我花了两个小时来搞清楚。
以下是您需要的代码：ptr-> WriteString（“：MMEM：STOR：FDAT'D：ramtry.csv'; * opc？ n”）;
ptr-> WriteString（“MMEM：TRAN？'D：ramtry.csv'; * opc？ n”）;
_bstr_t str1 = ptr-> ReadString（1）;
_bstr_t str2 = ptr-> ReadString（1）;
int count = atoi（str2）;
int num2 = atoi（ptr-> ReadString（count））;
_bstr_t result = ptr-> ReadString（num2）;
CString strResult =（CString）result.GetBSTR（）;
ofstream文件;
file.open（“C： ramtry.csv”，ios :: out）;
if（file.is_open（））{file} file.close（）;编辑：ningchen于2014年7月10日下午9:15
