i have created one method to write to Log file but each time it overrite the log details , i want to create a new entry everytime for logging details.My log method is as below :
void CNDSConnectDlg::WriteLogData()
{
CString strUserName = "";
m_editUserName.GetWindowText(strUserName);
FILE * pFile = NULL;
int iErr = 0;
iErr = fopen_s(&pFile,"NDSLog.txt","w");
if (iErr == 0)
{
CString strConnectionStatus = "";
CString strServerAddress = "";
CString strDateTime = "";
SYSTEMTIME systime;
GetLocalTime(&systime);
if(m_bConnectionStaus == true)
{
strConnectionStatus = "Success";
}
else
{
strConnectionStatus = "Failure";
}
strUserName.Format("%s",strUserName);
strConnectionStatus.Format("%s",strConnectionStatus);
strServerAddress.Format("%s",m_strIPAddress);
strDateTime.Format("%i:%i:%i\\%02i-%02i-%02i",
systime.wHour,
systime.wMinute,
systime.wSecond,
systime.wYear,
systime.wMonth,
systime.wDay);
fputs("UserName = " + strUserName + " connected to "
"ServerAddress = " +strServerAddress + " at "
"Date/Time = " + strDateTime + " "
"ConnectionStatus = " +strConnectionStatus + " ",pFile);
fclose (pFile);
}
else
{
MessageBox("Error in writing to Log","NDS",MB_ICONERROR | MB_OK);
}
}
Any help is highly appreciated .
Thanks in Advance.

I am downloading videos from my server in the application sandbox storage, at this path:
final String filePath = this.getExternalFilesDir("videos") + "/" + name + ".mp4";
Now, I want to copy some specific files from the path above to another folder in DCIM so users can discover the videos in the gallery.
I am able to create that file, but I don't understand how to copy and move the file.
File dir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM), "MyFolder");
if (!dir.exists()) {
boolean rv = dir.mkdir();
Log.d(TAG, "Folder creation " + ( rv ? "success" : "failed"));
}
Can anyone help?
Solved it using standard Java IO stream.
String inputFile = "/" + name + ".mp4";
String inputPath = this.getExternalFilesDir("videos") + "";
String outputPath = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM), "MyFolder") + "";
private void copyFile(String inputFile, String inputPath, String outputPath) {
try {
File dir = new File(outputPath);
if (!dir.exists()) {
if (!dir.mkdirs()) {
return;
}
}
try (InputStream inputStream = new FileInputStream(inputPath + inputFile)) {
try (OutputStream outputStream = new FileOutputStream(outputPath + inputFile)) {
File source = new File(inputPath + inputFile);
byte[] buffer = new byte[1024];
int read;
long length = source.length();
long total = 0;
while ((read = inputStream.read(buffer)) != -1) {
total += read;
int progress = (int) ((total * 100) / length);
if (progress == 100) {
Toast.makeText(VideoActivity.this, "Completed", Toast.LENGTH_SHORT).show();
}
outputStream.write(buffer, 0, read);
}
}
}
} catch (Exception e) {

I have pairs of strings that need to be replaced in the file names of a given folder, e.g. BUL to Bg-bg, ENG to En-us, etc. There are 12 such pairs. I have found a script to take care of a single pair of replacement but whenever I am trying to add more arguments, it somehow only loops through one and renames just one matching string. Cannot figure our a simpler code that would accept all replacement string pairs at once without creating a separate loop for each pair. Any ideas would be appreciated.
var sFolderName, sStringToFind;
var nResult;
sFolderName = "E:\\Users\\Username\\Desktop\\Sample"; // directory name
sStringToFind1 = "BUL";
sStringToReplace1 = "Bg-bg";
sStringToFind2 = "ENG";
sStringToReplace2 = "En-us";
nResult = renameFiles(sFolderName, sStringToFind1, sStringToReplace1, sStringToFind2, sStringToReplace2);
WScript.Echo(nResult + " files renamed");
// Function Name: renameFiles
// sFolder: Folder Name (use double backslashes)
// sString1: String to search for
// sString2: String to replace
// Returns: Number of files renamed
function renameFiles(sFolder, sString1, sString2, sString3, sString4) {
var oFSO, oFile, oFolder;
var re, index;
var sName;
var i = 0, n;
oFSO = new ActiveXObject("Scripting.FileSystemObject");
oFolder = oFSO.GetFolder(sFolder);
try {
index = new Enumerator(oFolder.Files);
for (; !index.atEnd(); index.moveNext()) {
oFile = index.item();
sName = oFile.Name;
n = sName.indexOf(sString1);
if(n != -1) {
try {
sName = sName.substring(0, n) + sString4 +
sName.substr(n + sString3.length);
oFile.Name = sName;
i++;
} catch(e) {
WScript.Echo("Can not rename file " + sName + " because\n" + e.description);
}
}
}
index = new Enumerator(oFolder.Files);
for (; !index.atEnd(); index.moveNext()) {
oFile = index.item();
sName = oFile.Name;
n = sName.indexOf(sString3);
if(n != -1) {
try {
sName = sName.substring(0, n) + sString4 +
sName.substr(n + sString3.length);
oFile.Name = sName;
i++;
} catch(e) {
WScript.Echo("Can not rename file " + sName + " because\n" + e.description);
}
}
}
}
catch(e) {
WScript.Echo("Could not access folder " + sFolder + " because\n" + e.description);
return 0;
} finally {
oFSO = null;
re = null;
return i;
}
}
You could use replace() and do all replacements inside the same loop:
function renameFiles(sFolder, sString1, sString2, sString3, sString4) {
var oFSO, oFile, oFolder;
var re, index;
var sName;
var i = 0, n;
oFSO = new ActiveXObject("Scripting.FileSystemObject");
oFolder = oFSO.GetFolder(sFolder);
try {
index = new Enumerator(oFolder.Files);
for (; !index.atEnd(); index.moveNext()) {
oFile = index.item();
sName = oFile.Name;
sName = sName.replace(sString1, sString2);
sName = sName.replace(sString3, sString4);
if (oFile.Name != sName) {
i++;
oFile.Name = sName;
}
}
}
catch(e) {
WScript.Echo("Could not access folder " + sFolder + " because\n" + e.description);
return 0;
} finally {
oFSO = null;
re = null;
return i;
}
}
Or you could use an array os pairs, and iterate through these pairs and pass any number of pairs...
renameFiles(sFolder, [
[sStringToFind1, sStringToReplace1],
[sStringToFind2, sStringToReplace2],
// ...,
[sStringToFindN, sStringToReplaceN],
]);
function renameFiles(sFolder, arrayOfPairs) {
var oFSO, oFile, oFolder;
var re, index;
var sName;
var i = 0, n;
oFSO = new ActiveXObject("Scripting.FileSystemObject");
oFolder = oFSO.GetFolder(sFolder);
try {
index = new Enumerator(oFolder.Files);
for (; !index.atEnd(); index.moveNext()) {
oFile = index.item();
sName = oFile.Name;
for (var j = 0; j < arrayOfPairs.length; j++) {
sName = sName.replace(arrayOfPairs[j][0], arrayOfPairs[j][1]);
}
if (oFile.Name != sName) {
i++;
oFile.Name = sName;
}
}
}
catch(e) {
WScript.Echo("Could not access folder " + sFolder + " because\n" + e.description);
return 0;
} finally {
oFSO = null;
re = null;
return i;
}
}
When I execute the code I developed to call an Async method of the linq2Twitter, I am getting a System.Aggregate Exception, the code is below:
static async Task<List<myTwitterStatus>> getRetweets(ulong tweetID, TwitterContext twitterCtx)
{
List<myTwitterStatus> reTweets = new List<myTwitterStatus>();
var publicTweets =
await
(from tweet in twitterCtx.Status
where tweet.Type == StatusType.Retweets &&
tweet.ID == tweetID
select tweet)
.ToListAsync();
if (publicTweets != null)
publicTweets.ForEach(tweet =>
{
if (tweet != null && tweet.User != null)
{
myTwitterStatus tempStatus = new myTwitterStatus();
tempStatus.Country = tweet.Place.Country;
tempStatus.createdAt = tweet.CreatedAt;
tempStatus.FavoriteCount = long.Parse(tweet.FavoriteCount.ToString());
tempStatus.ID = tweet.ID;
tempStatus.isTruncated = tweet.Truncated;
tempStatus.Lang = tweet.Lang;
tempStatus.MaxID = tweet.MaxID;
tempStatus.PlaceFullname = tweet.Place.FullName;
tempStatus.RetweetCount = tweet.RetweetCount;

tempStatus.UserName = tweet.User.Name;
tempStatus.UserTweetCount = tweet.User.StatusesCount;
reTweets.Add(tempStatus);
}
});
return reTweets;
}
The issue is when I called the method
var authorizer = new SingleUserAuthorizer

}
};
TwitterContext twitterCtx = new TwitterContext(authorizer);
Task<List<myTwitterStatus>> task = Task<List<myTwitterStatus>>.Factory.StartNew(() => getRetweets(ulong.Parse(tweet.StringId), twitterCtx).Result);
task.Wait();
List<myTwitterStatus> tempList = task.Result.ToList<myTwitterStatus>();
foreach (var ret in tempList)
{

I would appreciate any kind of assistance about it, I have no idea how to solve it.
Can you add a try/catch so see what the inner exception is.
try
{
//Perform your operation here
}
catch (AggregateException aex)
{
//Dive into inner exception
}
Thanks to all for the help, I activate the breakpoints for the specific exception and an additional validation was added, the issue was not in the async process, it was because it was trying to handle a null as an string, to hendle this error this line was modified sn = file.RemoveSpecialCharacters(ret.ScreenName ?? string.Empty);

MS Excel has eaten my head. It is randomly converting numbers into scientific notation format. This causes a problem when I load the file saved in tab delimited format into SQL Server. I know I can provide a format file and do lot of fancy stuff. But let's say I can't.
Is there a macro which loops over all the cells and if the number in a cell is in scientific notation format then it converts it to numeric format?
Say:
Input: spaces signify different cells.
1.00E13 egalitarian
Output after macro:
10000000000000 egalitarian
I am trying this in Excel 2007.
I wrote a simple C# program to resolve this issue. Hope it's of use.
Input:
Input directory where files reside (assuming files are in .txt format).
Output:
Output directory where converted files will be spit out.
Delimiter:
Column delimiter.

This works fairly well in case of huge files which we are unable to open in MS Excel.
Thanks Peter.
I updated your original work to:
1) take in an input file or path
2) only write out a processing statement after every 1000 lines read
3) write the transformed lines to the output file as they are processed so a potentially large string is not kept hanging around
4) added a readkey at the end so that console does not exit automatically while debuggging

An easier way would be to save it as a .csv file. Then, instead of just opening the file - you go to the Data tab and select "from text" so that you can get the dialogue box. This way you can identify that column with the scientific notation as text to wipe out that format. Import the file and then you can reformat it to number or whatever you want.

break;
}
}
}
I found it in :
CharacterRun run = para.getCharacterRun(i)
i should be integer and should be incremented so the code will be as follow :
int c=0;
while (true) {
CharacterRun run = para.getCharacterRun(c++);
int x = run.getPicOffset();
System.out.println("pic offset" + x);
if (run.getEndOffset() == para.getEndOffset()) {
break;
}
}
if (paragraph != null)
{
int numberOfRuns = paragraph.NumCharacterRuns;
for (int runIndex = 0; runIndex < numberOfRuns; runIndex++)
{
CharacterRun run = paragraph.GetCharacterRun(runIndex);
string color = getColor24(run.GetIco24());
}
}
GetColor24 Function to Convert Color in Hex Format for C#
public static String getColor24(int argbValue)
{
if (argbValue == -1)
return "";
int bgrValue = argbValue & 0x00FFFFFF;
int rgbValue = (bgrValue & 0x0000FF) << 16 | (bgrValue & 0x00FF00)
| (bgrValue & 0xFF0000) >> 16;
StringBuilder result = new StringBuilder("#");
String hex = rgbValue.ToString("X");
for (int i = hex.Length; i < 6; i++)
{
result.Append('0');
}
result.Append(hex);
return result.ToString();
}
if you are working on docx(OOXML), you may want to take a look on this:
import java.io.*
import org.apache.poi.xwpf.usermodel.XWPFDocument
fun test(){
try {
val file = File("file.docx")
val fis = FileInputStream(file.absolutePath)
val document = XWPFDocument(fis)
val paragraphs = document.paragraphs
for (para in paragraphs) {
println("-- ("+para.alignment+") " + para.text)
para.runs.forEach { it ->
println(
"text:" + it.text() + " "
+ "(color:" + it.color
+ ",fontFamily:" + it.fontFamily
+ ")"
)
}
}
fis.close()
} catch (e: Exception) {
e.printStackTrace()
}
}
