    <p>I have a working file rename java tool, now I want to add an if condition to run a commandline command if I checked a box as part of the rename process on each file it renames.</p> <p>I will be changing the dos code later, but its a sample I found that works. Part of my problem is my filerename is its own class, so I will also need to figure out how to combine this class or reference the dos command somehow from my main rename class.</p> <p><strong>update</strong></p> <p>I updated the code with the changes from the answer, but the commandline command does not work and it crashes java with no error. The command does work from cmd line.</p> <pre><code>import java.io.IOException; import java.io.InputStream; public class doscommandrun { public static void run() { final String dosCommand = "cmd converter.exe file.doc -android -o file.txt"; try { final Process process = Runtime.getRuntime().exec( dosCommand + " "); final InputStream in = process.getInputStream(); int ch; while((ch = in.read()) != -1) { System.out.print((char)ch); } } catch (IOException e) { e.printStackTrace(); } } } </code></pre> <p><code>enter code here</code>File rename code:</p> <pre><code>private void renameFile(){ boolean operationResult = false; boolean overallResult = true; int failCount = 0; /* the operation of this part is ensured by the chooseDirectory() * WE get the list of files in the directory * get the conditions set by users * and perform the file rename operation. */ //Let's get all the information from user String[] fileList = directory.list(); //the list of files in the directory String Prefix = txtPrefix.getText(); String Rename = txtRename.getText(); String Suffix = txtSuffix.getText(); String digits = (String) cboSequence.getSelectedItem(); int StartingNum; String generatedSequence; File oldFile; //let's call the output frame if(cbxOutput.isSelected() &amp;&amp; OUTPUT_ON == false){ buildOutput(); OUTPUT_ON = true; } //display the list of files and readability of each file for(int i = 0; i &lt; fileList.length; i++){ oldFile = new File(directory.getPath()+"/"+ fileList[i]); String readability = fileList[i] +" - readable?: "+oldFile.canRead(); System.out.println(readability); if(OUTPUT_ON) txaOutput.append("\n"+readability); } for(int i = 0; i &lt; fileList.length; i++){ /* get the file extension that we need, and form a new name, * we would check if the Ignore File Extension is selected */ oldFile = new File(directory.getPath()+"/"+ fileList[i]); String fileExtension; if(cbxIgnoreExtension.isSelected() == true ){ fileExtension = ""; } else fileExtension = getFileExtension(fileList[i]); //this part get the original filename String fileName = getFileName(fileList[i]); String inputInfo = "The input filename-&gt;"+ fileList[i] + "\nfile name-&gt;" + fileName + "\nextension-&gt;" + fileExtension; System.out.println(inputInfo); if(OUTPUT_ON) txaOutput.append("\n"+inputInfo); /* generate sequence for the Name *if the digits selection is NONE, we ignore it */ if(digits.equals("None") == true){ generatedSequence = ""; } else{ StartingNum = Integer.parseInt(txtSequence.getText()); generatedSequence = nameSequence(StartingNum + i, digits); } //this is affected by the RenameOption, if Rename has something then only we RENAME if(cbxRename.isSelected() == true){ fileName = Rename + generatedSequence; //the fileName will change. } else{ //if Rename has nothing, but the txtSequence has some Value, we take it to the naming too fileName = fileName.substring(0,4)+ generatedSequence; if(cbxAndroid.isSelected() == true ){ doscommandrun.run(); } //the New File Name String newFileName = Prefix + fileName.substring(0,4) + Suffix + fileExtension; String tentativeName = "new Filename will be -&gt;"+newFileName+"\n"; System.out.println(tentativeName); if(OUTPUT_ON) txaOutput.append("\n"+tentativeName); // !

    2. CO@jerhynsoen You have to read data both from input and error streams of your process. Otherwise, you will run into problem when error occurs. For this you will have to use Threads.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
