In my code has an issue but I can't see what issue in this. Column names are same word by word and it is working, If I use 1 column in csv file but when I try out more then 2-3 column fields it is giving the error below. I have checked read lots of article so I can't fix the error. What can be happen with is this lines. DB already was created with similar fields.

Some information can be found here: https://sqlbulkcopy-tutorial.net/columnmapping-does-not-match
Cause
You didn't provide any ColumnMappings, and there is more column in the source than in the destination.
You provided an invalid column name for the source.
You provided an invalid column name for the destination.
Solution
ENSURE to provide a ColumnMappings
ENSURE all values for source column name are valid and case sensitive.
ENSURE all values for destination column name are valid and case sensitive.
MAKE the source case insensitive
I have found a solution and working 100% true.. The link below, I hope become a path who need that.

I'm trying to merge all my text files into one file.
The problem I am having is that the file names are based on data previously captured in my app. I don't know how to define my path to where the text files are, maybe. I keep getting a error, but the path to the files are correct.
What am I missing?
string filesread = System.AppDomain.CurrentDomain.BaseDirectory + #"\data\Customers\" + CustComboB.SelectedItem + #"\";
Directory.GetFiles(filesread);
using (var output = File.Create("allfiles.txt"))
{
foreach (var file in new[] { filesread })
{
using (var input = File.OpenRead(file))
{
input.CopyTo(output);
}
}
}
System.Diagnostics.Process.Start("allfiles.txt");
my error:
System.IO.DirectoryNotFoundException
HResult=0x80070003
Message=Could not find a part of the path 'C:\Users\simeo\source\repos\UpMarker\UpMarker\bin\Debug\data\Customers\13Dec2018\'.
I cant post a pic, but let me try and give some more details on my form.
I select a combobox item, this item is a directory. then I have a listbox that displays the files in my directory. I then have a button that executes my desires of combining the files. thanks
I finally got it working.
string path = #"data\Customers\" + CustComboB.SelectedItem;
string topath = #"data\Customers\";
string files = "*.txt";
string[] txtFiles;
txtFiles = Directory.GetFiles(path, files);
using (StreamWriter writer = new StreamWriter(topath + #"\allfiles.txt"))
{
for (int i = 0; i < txtFiles.Length; i++)
{
using (StreamReader reader = File.OpenText(txtFiles[i]))
{
writer.Write(reader.ReadToEnd());
}
}
System.Diagnostics.Process.Start(topath + #"\allfiles.txt");
}
Tried with
cellValue= worksheet.getRow(1).getCell(1).value;
and
cellValue=console.log(worksheet.getCell('A1'))
please find below my code :
cellread2=function(){
var Excel;
var filePath = path.resolve(__dirname,'E:/excel.xlsx');
if (typeof require !== 'undefined') {
Excel = require('C:/Users/user/AppData/Roaming/npm/node_modules/exceljs/dist/exceljs');
}
var wb = new Excel.Workbook();
console.log(wb);
wb.xlsx.readFile(filePath);
var worksheet = wb.getWorksheet('Sheet1');
//cellValue= worksheet.getRow(1).getCell(1).value;//Error :TypeError: Cannot read property 'getRow' of undefined
cellValue=console.log(worksheet.getCell('A1'))// TypeError: Cannot read property 'getCell' of undefined
console.log(cellValue);
}
There is a problem with the existing library code. If you want to make it work you will have to make few changes in the existing code in file AppData\Roaming\npm\node_modules\exceljs\dist\es5\xlsx\xform\sheet\worksheet-xform.js. Replace the code at line 284 with the following :
if (drawing.anchors && drawing.anchors.length > 0) {
drawing.anchors.forEach(function (anchor) {
if (anchor.medium && anchor.range) {
var image = {
type: 'image',
imageId: anchor.medium.index,
range: anchor.range
};
model.media.push(image);
}
});
}
And as for the code for reading the file use the following code.
Note: I installed exceljs library globally and I am using version 4.6.1
var path = require('path');
var Excel = require('exceljs');
var cellread2 = function () {
var filePath = path.resolve('E:', 'excel.xlsx');
var wb = new Excel.Workbook();
wb.xlsx.readFile(filePath).then(function (data) {
var worksheet = wb.getWorksheet('Sheet1');
var cellValue = worksheet.getRow(1).getCell(1).value;
console.log('cellValue', cellValue);
}).catch(function (e) {
console.log(e);
});
}
cellread2();
It may occurs due to objects are mapped into the excel sheet instead of textual data.
Please create another excel sheet and check it again will resolve this issue.'
Sample code to read excel sheet using node.js is given below,
var Excel = require('exceljs');
var wb = new Excel.Workbook();
var path = require('path');
var filePath = path.resolve(__dirname,'sample.xlsx');
wb.xlsx.readFile(filePath).then(function(){
var sh = wb.getWorksheet("Sheet1");
sh.getRow(1).getCell(2).value = 32;
wb.xlsx.writeFile("sample2.xlsx");
console.log("Row-3 | Cell-2 - "+sh.getRow(3).getCell(2).value);
console.log(sh.rowCount);
//Get all the rows data [1st and 2nd column]
for (i = 1; i <= sh.rowCount; i++) {
console.log(sh.getRow(i).getCell(1).value);
console.log(sh.getRow(i).getCell(2).value);
}
});
In my case the sheet name did not match with 'Sheet1', since I was modifying an existing excel file. Replacing the sheet name resolved the issue.
Seem like I'm not the first to investigate this. But not despairing yet :-)
The target state I'd like to reach is:
A recursion through Packages, where some of the nested Sub-Packages are glorified Linked Documents, and some are Grids rendering Search Results.
I like that Model Documents provide Search Tag values -- but I can't seem to nest the grids where I want them to show up.
Approach 1: Nested Model Documents
If I could nest Model Document elements, with their Search/Search Term tags, I would be sorted. I could have
Context:Package
Introduction:Package <- just renders a Linked Document attached to it
Systems Affected:Package <- just renders a Linked Document attached to it
Systems Affected:Model Document <- renders the results of a canned Search.
But EA appears to be designed to ignore the Model Document element.
Approach 2: SQL backed Template Fragment
I like the Model Document as it has Search/Search Term + all the Inclusion/Exclusion configuration options. But if I had to give that part up I am thinking of emulating as much as I can via SQL or script.
First attempt - using SQL and a nested set of Packages such as:
Context:Package
Introduction:Package <- just renders a Linked Document attached to it
Systems Affected:Package <- just renders a Linked Document attached to it
Systems Affected:Package<> <- renders the results of a SQL Search.
If the template uses a TemplateSelector it can spot the Package with a wellknown stereotype, and invoke a Template that is backed by SQL.
The SQL uses the Package's Keywords as the source of the Element type to search for.
SELECT
o.ea_guid AS [CLASSGUID],
o.Object_Type AS [CLASSTYPE],
o.PDATA5 AS [KEYWORDS],
o.Object_Type AS [Type],
o.Stereotype AS [Stereotype],
*
FROM t_object as O
WHERE O.Object_Type IN
(SELECT PDATA5 FROM t_object AS S where S.Object_ID = #OBJECTID#)
It works...barely.It's a bit hacky.
Searching off of Element Type is not going to be sufficient for production documents.
Approach 3: Script backed Template Fragment
If I can get a script running I suspect that I could leverage functionality that is already in the system.
Context:Package
Introduction:Package <- just renders a Linked Document attached to it
Systems Affected:Package <- just renders a Linked Document attached to it
Systems Affected:Package<> <- renders the results of a canned Search.
If the template uses a TemplateSelector it can spot the Package with a wellknown stereotype, and invoke a Template that is backed by a script.
The script I'm trying is:
var x = Repository.GetElementsByQuery("POC.Req", "Device");
return x;
But the report remains blank of those elements I need for the table.
Q: Does the returned Collection need transformation before it can be used?
Approach 4
I've heard that there is an approach to Render Document sections as PDF, and link to them as Linked Documents... Sounds Convoluted. Sounds like a wrong/magic approach.
Approach 5
Any other suggestions?
Thanks for the help.
Addendum
Just got approach 3 to work by converting the script results to xml before handing it back
The template's script now looks like
-- first pass ...I'll work on passing the ObjectId in a bit in order to get fancier.
ExecuteSearch("Simple", "Device")
and it invokes a script saved somewhere else as
!INC Local Scripts.EAConstants-JScript
/*

* Author:
* Purpose:
* Date:
*/
function main()
{
return ExecuteSearch("Simple", "Device");
}
function ExecuteSearch(searchName, searchParam){
var x = Repository.GetElementsByQuery(searchName, searchParam);
//return x;
var xmlDOC = CreateReport(x);
var s = xmlDOC.xml;
Session.Output(s);
return s;
}
function CreateReport(entityCollection){
var xmlDOC = CreateXmlDOC();
var xmlRoot = AppendXmlChild(xmlDOC,"EADATA");
var xmlDataSet = AppendXmlChild(xmlDOC,"Dataset_0",xmlRoot);
var xmlData = AppendXmlChild(xmlDOC,"Data",xmlDataSet);
for(var i = 0;i<entityCollection.Count();i++){
var entity = entityCollection.GetAt(i);
var xmlRow = AppendXmlChild(xmlDOC,"Row",xmlData);
//AppendXmlChild(xmlDOC,"CLASSTYPE",xmlRow).Text = entity.Type;
AppendXmlChild(xmlDOC,"Guid",xmlRow).text = entity.ElementGUID;
AppendXmlChild(xmlDOC,"CLASSTYPE",xmlRow).text = entity.Type;
AppendXmlChild(xmlDOC,"CLASSGUID",xmlRow).text = entity.ElementGUID;
AppendXmlChild(xmlDOC,"Type",xmlRow).text = entity.Type;

AppendXmlChild(xmlDOC,"Scope",xmlRow).text = entity.Scope;
AppendXmlChild(xmlDOC,"Phase",xmlRow).text = entity.Phase;
AppendXmlChild(xmlDOC,"Status",xmlRow).text = entity.Status;
var noteElement = AppendXmlChild(xmlDOC,"Notes",xmlRow);//.text = entity.Notes;
noteElement.appendChild(xmlDOC.createCDATASection(entity.Notes));
AppendXmlChild(xmlDOC,"Keywords",xmlRow).text = entity.PDATA5;
}
return xmlDOC;
}
function CreateXmlDOC()
{
var xmlDOM;
try
{
xmlDOM = new ActiveXObject( "MSXML2.DOMDocument.4.0" );
}
catch(e)
{
xmlDOM = new ActiveXObject( "MSXML2.DOMDocument.6.0" );
}
xmlDOM.createProcessingInstruction("xml","version=\"1.0\"");
xmlDOM.validateOnParse = false;
xmlDOM.async = false;
return xmlDOM;
}
function AppendXmlChild(xmlDOM, xmlElementName, xmlParent, isCDATA){
if (!xmlParent){xmlParent = xmlDOM;}
var child = xmlDOM.createElement(xmlElementName);
xmlParent.appendChild(child);
return child;
}
main();
The script I used in the end is as follows. It now correctly investigates the element's tags for clues as how to proceed.
Hope it helps others.

I want to export MS word(docx/doc) document pages to Image(jpeg/png).
I am doing same for presentation(pptx/ppt) using office interop export api for each slide, but didn't found corresponding API for word.
Need suggestion for API/alternate approach for achieving this.
Based on this similar question: "Saving a word document as an image" you could do something like this:
const string basePath = #"C:\Users\SomeUser\SomePath\";
var docPath = Path.Combine(basePath, "documentA.docx");
var app = new Application()
{
Visible = true
};
var doc = app.Documents.Open(docPath);
foreach (Window window in doc.Windows)
{
foreach (Pane pane in window.Panes)
{
for (var i = 1; i <= pane.Pages.Count; i++)
{
var page = pane.Pages[i];
var bits = page.EnhMetaFileBits;
var target = Path.Combine(basePath, string.Format("page-no-{0}", i));
using (var ms = new MemoryStream(bits))
{
var image = Image.FromStream(ms);
var pngTarget = Path.ChangeExtension(target, "png");
image.Save(pngTarget, ImageFormat.Png);
}
}
}
}
app.Quit();
Basically, I'm using the Page.EhmMetaFileBits property which, according to the documentation:
Returns a Object that represents a picture representation of how a
page of text appears.
... and based on that, I create an image and save it to the disk.
