I just finished creating a program (I am a beginner at this programming stuff) Now I might be doing this the total wrong way or my logic might not be the greatest at programming but any help would be amazing I will post my code so far below
This code is used when a button is clicked, the button will send a text then the textbox will get the text.
if (txt1.Text == "")
{
txt1.Text = "J";
btn1.Visible = false;
}
else if (txt1.Text != "")
{
if (txt2.Text == "")
{
txt2.Text = "J";
btn1.Visible = false;
}
else if (txt2.Text != "")
{
if (txt3.Text == "")
{
txt3.Text = "J";
btn1.Visible = false;
}
else if (txt3.Text != "")
{
if (txt4.Text == "")
{
txt4.Text = "J";
btn1.Visible = false;
}
else if (txt4.Text != "")
{
if (txt5.Text == "")
{
txt5.Text = "J";
btn1.Visible = false;
}
else if (txt5.Text != "")
{
if (txt6.Text == "")
{
txt6.Text = "J";
btn1.Visible = false;
}
else if (txt6.Text != "")
{
if (txt7.Text == "")
{
txt7.Text = "J";
btn1.Visible = false;
}
else if (txt7.Text != "")
{
if (txt8.Text == "")
{
txt8.Text = "J";
btn1.Visible = false;
}
else if (txt8.Text != "")
{
}
}
}
}
}
}
}
}
You need to get all of these text cases into an array for the following loop to work (I have called the array 'txt' here). Based on what you have written this loop should do the same thing as your code but I'm not sure if that's what you really want to do. Your code is setting a single text box to "J" and then hiding your button only if every preceding text field is not an empty string (This will include any of the fields set to null, for example). The conditional then exits.
`for (int i = 0; i < txt.Length; i++) {
if(txt[i] != "") {
continue;
}
else if(txt[i] == "") {
txt[i] = "J";
btn1.Visible = false;
break;
}
}
Note: I don't know whether this works for C# 3 or not (it should). Try it.
First, you should put all of your text fields into an array:
TextField[] textFields = { txt1, txt2, txt3, txt4, txt5, txt6, txt7, txt8, };
Then, loop through the text fields to find a text field that has no text in it:
foreach (TextField tf in textFields) {
if (tf.Text == "") {
}
}
After we find it, we want to set its text to "J" and make btn1 invisible. Since we already found the text field, we don't need to continue the loop anymore, so we break:
tf.Text = "J";
btn1.Visible = false;
break;
If this doesn't work in C# 3, just update to C# 5 or 6 alright?

How to determine whether a list is bulleted or numbered? I use OpenXML
In general, what will be the list determines NumberingDefinitionsPart, I thought to find out the Numbering of a certain element, but this method did not work
I am processing the list in the recommended way, but I need to know which way it is
`public void ParagraphHandle(Elements.Paragraph paragraph, StringBuilder text)
{
var docPart = paragraph.DocumentPart;
var element = paragraph.Element;
var r = element.Descendants<Numbering>().ToArray();
var images = GetImages(docPart, element);
if (images.Count > 0)
{
foreach (var image in images)
{
if (image.Id != null)
{
string filePath = _saveResources.SaveImage(image);
_handler.ImageHandle(filePath, text);
}
}
return;
}
var paragraphProperties = element.GetFirstChild<ParagraphProperties>();
var numberingProperties = paragraphProperties?.GetFirstChild<NumberingProperties>();
if (numberingProperties != null)
{
var numberingId = numberingProperties.GetFirstChild<NumberingId>()?.Val?.Value;
if (numberingId != null && !paragraph.IsList)
{
text.AppendLine("<ul>");
paragraph.IsList = true;
paragraph.List = new List();
_htmlGenerator.GenerateList(paragraph, text);
}
else
{
_htmlGenerator.GenerateList(paragraph, text);
}
}
else
{
if (paragraph.IsList)
{
text.AppendLine("</ul>");
paragraph.IsList = false;
}
_handler.ParagraphHandle(element, text);
}
}`
I get this error and I don't know why. I basically just check the operator and make calculations based on that.
Thank you for your help.
Function:
void calculate() {
setState(() {
int num1int = int.tryParse(_num1);
int num2int = int.tryParse(_num2);
int result = 0;
if (_operator == "+") {
result = num1int + num2int;
}
else if (_operator == "-") {
result = num1int - num2int;
}
else if (_operator == "*") {
result = num1int * num2int;
}
else if (_operator == "/") {
result = num1int ~/ num2int;
}
});
}
if "int.tryParse" can not convert it into integer, it will be returning "null". So your code does: null + null. You can add a check for num1int and num2int if it is null before calcultion.
please change your code to
if (_operator == "+") {
result = num1int??0 + num2int??0;
}
else if (_operator == "-") {
result = num1int??0 - num2int??0;
}
else if (_operator == "*") {
result = num1int??1 * num2int??1;
}
else if (_operator == "/") {
result = num1int??1 ~/ num2int??1;
}
I am trying to display invalid user credentials in textview by concatenating the invalid fields.So that i get a textview like invalid name,username,contact...at a time.
I want the invalid fields to display at a time.
I have declared a string and tried to concatenate but the result is textview displays all the fields even if its valid one.
boolean flag = true;
String s1,s2,s3,s4,s5;
boolean checkDataEntered() {
if (isEmpty(Name)) {
Name.setBackgroundResource(R.drawable.error);
s1="Full name";
flag = false;
}
if (isEmpty(Username)) {
Username.setBackgroundResource(R.drawable.error);
s2="Username";
flag = false;
}
if (isEmail(EmailId)) {
EmailId.setBackgroundResource(R.drawable.error);
s3="Email";
flag = false;
}
if (flag) {
return true;
} else {
textView7.setText("Please fill"+s1+ s2+ s3) ;
return false;
}
}
This is because you are concatenating all the fields in your else statement.
textView7.setText("Please fill"+s1+ s2+ s3);
But your requirement is to concatenate it only if it is empty. So you should try like,
boolean flag = true;
String error = "";
boolean checkDataEntered() {
if (isEmpty(Name)) {
Name.setBackgroundResource(R.drawable.error);
error += "Full name";
flag = false;
}
if (isEmpty(Username)) {
Username.setBackgroundResource(R.drawable.error);
error += ",Username";
flag = false;
}
if (isEmail(EmailId)) {
EmailId.setBackgroundResource(R.drawable.error);
error += ",Email";
flag = false;
}
if (flag) {
return true;
} else {
textView7.setText("Please fill "+error) ;
return false;
}
}
Kindly see below code I am using to convert Mirth xml to JSON.
function E4XtoJSON(xml, ignored) {
var r, children = xml.*, attributes = xml.#*, length = children.length();
if(length == 0) {
r = xml.toString();
} else if(length == 1) {
var text = xml.text().toString();
if(text) {
r = text;
}
}
if(r == undefined) {
r = {};
for each (var child in children) {
var name = child.localName();
var json = E4XtoJSON(child, ignored);
var value = r[name];
if(value) {
if(value.length) {
value.push(json);
} else {
r[name] = [value, json]
}
} else {
r[name] = json;
}
}
}
if(attributes.length()) {
var a = {}, c = 0;
for each (var attribute in attributes) {
var name = attribute.localName();
if(ignored && ignored.indexOf(name) == -1) {
a["_" + name] = attribute.toString();
c ++;
}
}
if(c) {
if(r) a._ = r;
return a;
}
}
return r;
}
My concern is
<AdditionalMessageInformationCount AdditionalMessageInformationCount="02"><AdditionalMessageInformationQualifier>01</AdditionalMessageInformationQualifier><AdditionalMessageInformation>MEMBER MUST USE MAIL ORDER.</AdditionalMessageInformation><AdditionalMessageInformationQualifier>02</AdditionalMessageInformationQualifier><AdditionalMessageInformation>PLAN LIMITATIONS EXCEEDED</AdditionalMessageInformation></AdditionalMessageInformationCount>
Here AdditionalMessageInformation elemt is used two times so function fails to create JSON.
Kindly help if anyone have converted XML in json usingg javascript code not any API
We've had success with this version:
function E4XtoJSON(xml, ignored){
var r, children = xml.*,
attributes = xml.# * ,
length = children.length();
if (length == 0)
{
r = xml.toString();
}
else if (length == 1)
{
var text = xml.text().toString();
if (text)
{
r = text;
}
}
if (r == undefined)
{
r = {};
for each(var child in children)
{
var name = child.localName();
var json = E4XtoJSON(child, ignored);
var value = r[name];
if (value)
{
if (value instanceof Array)
{
value.push(json);
}
else
{
r[name] = [value, json]
}
}
else
{
r[name] = json;
}
}
}
if (attributes.length())
{
var a = {},
c = 0;
for each(var attribute in attributes)
{
var name = attribute.localName();
if (ignored && ignored.indexOf(name) == -1)
{
a["_" + name] = attribute.toString();
c++;
}
}
if (c)
{
if (r) a._ = r;
return a;
}
}
return r;
}
With the release of Mirth Connect version 3.3.0, you can use Mirth Connect to set your channel's interior data type to JSON. This will all be done for you.
I have a page where I am displaying some text in a div and I need to highlight this text in certain parts. I have done this by surrounding the text I need to highlight with a tag and appropriate css styling.
E.g.
<div>
My text will look like this with <span class="highlight">highlighted bits</span> in it.
</div>
This works fine. However, another requirement for this page is that the user must be able to select texts, click a button, and the selected text must be highlighted too.
The problem I have is when trying to identify the range of the selected text to grab (using window.getSelection.getRangeAt(0)), this gives me the range which resets after every <span> tag in the text, not from the beginning of the text.
For those who would like to know in the future this is how I did it:
jQuery.fn.highlight = function(startOffset,endOffset,type) {
function innerHighlight(node, startOffset,endOffset) {

startOffset = resizeOffsetForNode(startOffsetNode,parseInt(startOffset));
if (startOffsetNode == endOffsetNode){
endOffset = resizeOffsetForNode(endOffsetNode,parseInt(endOffset));
highlightSameNode(startOffsetNode, parseInt(startOffset),parseInt(endOffset),type,calledStartOffset);
} else {
highlightDifferentNode(startOffsetNode,endOffsetNode,parseInt(startOffset),parseInt(endOffset),type,calledStartOffset);
}
}
return this.each(function() {
innerHighlight(this, startOffset,endOffset);
});
};
function resizeOffsetForNode(offsetNode,offset){
if (offsetNode.id >= 0){
offset = parseInt(offset)-parseInt(offsetNode.id);
} else if (offsetNode.previousSibling != null && offsetNode.previousSibling.id > 0){
offset = parseInt(offset)-parseInt(offsetNode.previousSibling.id)-parseInt(offsetNode.previousSibling.textContent.length);
}
return offset;
}
function getChildNodeForOffset(testNode,offset) {
if (testNode.nodeType == 1 && testNode.childNodes && !/(script|style)/i.test(testNode.tagName)) {
var offsetNode=null;
var currentNode;
for (var i = 0; i < testNode.childNodes.length; ++i) {
currentNode=testNode.childNodes[i];
if (currentNode.id >= 0 && parseInt(currentNode.id) <= parseInt(offset) && ((parseInt(currentNode.id) + parseInt(currentNode.textContent.length)) >= parseInt(offset))){
offsetNode = currentNode;
break;
} else if (currentNode.id >= 0 && parseInt(currentNode.id) > parseInt(offset)){
