What kind of transaction are you talking about? SQL transactions? System.Transactions? Client/server transactions?
|
|
|
|
|
So what you want to do is to auto increment the transactions number, with the transaction number being a variable within your code.
If I understand correctly.
Do you only use the app or do you use sql with your app?
I would say that if its just within your app the best would be
int trans = 0;
Number++;
or if you use sql you can set that each new entry must be unique and auto increment where you can specify the starting point and the amount with wich to increment.

Hi, I'm a newbie at C#, I was wondering if there was a code for knowing the location of the current open C# document. Let's say I want to know the location(In string form) of Form1.cs, is there any code to represent this?
Thank you very much 
|
|
|
|
|
Can you be more specific? The opened C# file...are you trying to find out the file path of a C# file Visual Studio has opened?
|
|
|
|
|
Yes. Because I want to access a folder that is located in the same folder as the file but I can't seem to access it.
it looks like this:
Folder1 contains
-Form1.cs
-FolderIwantToAccess contains pic.bmp
I want to access pic.bmp from Form1.cs
Thanks a lot!

Your .cs file doesn't execute directly. It gets compiled into your .exe file located in your \bin\debug\ directory. So your C# code will want to locate the bitmap relative to that directory.
If your directory structure is
MyProject
-FolderIWantToAccess
-bin
-Debug
Then you can access the image from your app using "..\\..\\FolderIWantToAccess\\pic.bmp"

I tried it but the program still doesnt read the picture file...I want to access the pic.bmp without directly enforcing the complete filepath (e.g. c:\mydocuments\sample\project\folderiwanttoaccess\pic.bmp <--i dont want to write this in the program source file...)

I understand what you're trying to do.
You can access files in a higher directory level that the exe using "..\\". So if your .exe file is running from c:\mydocuments\sample\project\bin\debug\test.exe, you can locate the image from your C# code using
// Adjust the line below depending on how many parent directories must be navigated upwards to read the folderIWantAccessTo directory.
stromg pathToImage = "..\\..\\..\\folderIWantAccessTo\pic.bmp";
If you want to see what's going on with those "..\\" things, see what this returns:
string path = Path.GetFullPath("..\\..\\..\\");
It should return your project root. From there the rest is easy, just append the folderIWantAccessTo\pic.bmp to the end of the string and you're good.

I figured out what was lacking in your idea... there should be three "." instead of two. It is now working correctly. Thanks very much

ei guys... i'm having a problem in printing the receipt for my point of sale. Just want to ask you... what tools should i used for the reciept and maybe some codes in printing it... thanks
|
|
|
|
|
Most printers are graphics printers. I have found that I can create class that builds the receipt as an image then send it to the printer. The api's are usually availiable from the mfg to configure the printer and they will give you examples.
I went this direction because getting text lined up is pretty difficult and in the end just looks bad.

Hi,
Can you show me any snippet or any library in order to extract text from RTF file ( or you can say, convert RTF file to txt file) PLeaseeeee

Hi,
Use rich text box control.
It has a rtf property to which you should set the rtf code and then in the text property of the rich text box you will get the plain code.
But If u want a function or something then sorry I don't know.

I am attempting to write a method to iterate through a xml file that has multiple nodes that match a given type but for some reason it only accepts the first one and then exists. I think I may have my loop wrong or something. Can anyone tell me what the issue may be? 
using System;
using System.IO;
using System.Xml;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Diagnostics;
using System.Threading;
namespace UTS_Batch_Update

public class UTSB_Input
{
{
string Path = "C:\\xmlticketID.xml";
// If the user forgets to put in a path, throw a NullException.
if (Path == null)
{
throw new ArgumentNullException();
}
// Load the document.
XmlDocument sourceDoc = new XmlDocument();
sourceDoc.Load(Path);
// Retrieve each ticketID.
//XmlNodeList tickets = sourceDoc.GetElementsByTagName("TicketId");
//Create an XmlNamespaceManager for resolving namespaces.
XmlNamespaceManager nsmgr = new XmlNamespaceManager(sourceDoc.NameTable);
foreach (XmlNode node in tickets)
if (node.Name == "TicketId")
{
//using (MemoryStream buffer = new MemoryStream())
string buffer = "c:\\xmlpost.xml";
XmlTextWriter w = new XmlTextWriter(buffer, null);
// Start the document.
w.WriteStartDocument();
w.WriteStartElement("XMLFILE");
w.WriteAttributeString("UserLogName", "REDMOND\\" + UserInfo);

Yes, you have. You have the return statement inside the loop.

Is there anyway to set a tooltip for a certain coordinate area of a form and not to a specific control?
|
|
|
|

I figured out one way to do it, but I don't know if it's the most efficient.
This is what I did:
<br />
private void Form1_MouseMove(object sender, MouseEventArgs e)<br />
{<br />
if (e.X > 15 && e.X < 45 && e.Y > 35 && e.Y < 60)<br />
trackTip.Show("1", this, 20, 45);<br />
else if (e.X > 45 && e.X < 75 && e.Y > 35 && e.Y < 60)<br />
trackTip.Show("2", this, 55, 45);<br />
else<br />
trackTip.Hide(this);<br />
}<br />
is this the best way to do it?

I'm trying to capture system messages in my Windows Service. Specifically I want to know when a device is un\plugged into the usb. From what I found is appears that I need to 1) Create a callback HandlerEx, 2)RegisterServiceCtrlHandlerEx and 3)RegisterDeviceNotification.
My Problem is I always get a Error 126 when I call RegisterServiceCtrlHandlerEx. I think something might be wrong with the parameters I am passing it.
Would appreciate any suggestions or any advise on a better way to do this.
First Section of code is my Win32 class and delegate for my callback. Second section is The Service code minus all the windows generated stuff.
using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace My_Service
{
public delegate int callbackEx(int control, int eventType,IntPtr eventData,IntPtr context);
class Win32
{
[DllImport("kernel32.dll")]
public static extern int GetLastError();
[DllImport("advapi32.dll", SetLastError=true)]
public static extern IntPtr RegisterServiceCtrlHandlerEx(
string lpServiceName,callbackEx cbex,IntPtr context);
}
}
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.ServiceProcess;
namespace My_Service
{
public class My_Service: System.ServiceProcess.ServiceBase
{
private System.ComponentModel.IContainer components;
public System.Diagnostics.EventLog eventLog1;
private IntPtr MethodHandle;
private callbackEx myCallback ;
public My_Service()
{
// This call is required by the Windows.Forms Component Designer.
InitializeComponent();
this.RegisterCallBack();
}
private int my_Callback(int dwControl,int dwEventType,IntPtr lpEventData,IntPtr lpContext)
{
this.eventLog1.WriteEntry("CALLBACK HIT!!!!!!!!!!");
return 0;
}
void RegisterCallBack()
{
myCallback = new callbackEx(my_Callback);
MethodHandle = Win32.RegisterServiceCtrlHandlerEx(this.StrToByteArray(this.ServiceName),myCallback,IntPtr.Zero);
if(MethodHandle == IntPtr.Zero)
{
this.eventLog1.WriteEntry("RegisterCallBack " + Win32.GetLastError().ToString());
}
}
Thanks, Chris

Hi all,
I'm really struggling to do something very simple using a DataGridView control. I'm setting the DataGridView DataSource to an existing DataSet. All the data is displayed fine.
I now want to select a range of cells using the DataGridView, and when I click a button, have the selected cells copied to a new (previously empty) dataset. I just can't figure out how to get the data I've selected in the DataGridView control into the new dataset.
By putting a watch on the DataGridView control, I can see the list of items contained in the control, but they're all non-public so I have no way of getting at them programmatically.
Any assistance would be very much appreciated.

I don't know if I have understood the question right but you can access the cells with
[code]
dataGridView1.Rows[0].Cells[1].Value;
[\code]
hope this helps

if u are looking for this
on selectedindexchanged of gridview1 write code below
this.textbox1.text = GridView1.SelectedRow.Cells[1].Text
