Problem with Threads and a Sliding PopUp (MSN-Lookalike) - C# Discussion Boards

How about checking the file creation date against the current date, deleting the file if its "too old" and returning with an error, causing re-reading of the file or prompting the user to restart?

Cheers,

Using the time has crossed my mind. If my loader program names the file using the time, say rounded off to 30 seconds, then the loaded program uses the same algorithm to determine the filename to look for. If the loaded program starts more than 30 seconds after the loader, it will miss the file and show a dialogue to get the required argument.

When i search, all i find is custom menus, which would change the colour, but are a bit over the top

Doesn't matter, i ditched the menu all togeather, now i have a series of buttons, ooh

Hi I am developing a scripts in C# which can be used to test windows based applications. I use Win32 API's to perform click operations etc. To uniquely identify a control in a window rather than using absolute position of a control I have been using Control-ids and captions of the control. But I found scenarios where the control-id was dynamic and the control didn't have a caption. What I mean by caption is the text of the control. A control, say a button can have both name and text - Name: btnOk and Caption: OK. What I hoping to get is the Name "btnOk" that can uniquely identify it in a window because no two controld can have the same name, but it can have the same caption. I have searched through the Win32 API's and I have been able to find a suitable API that does the job. Any kind of help will be appreciated. Thanks a lot.

Hi,
afaik the Handle of each window is unique. Everything (visual) has a handle.

Thanks mikone for the reply, but I have come across certain Win Forms where the Handle of the control changes each time I call the Application. For eg. I bring up Calculator (here it is same just for eg. sake) each time the handle for the button 7 may not be same. I am not sure if the forms are .NET forms. They could be VC based Win Forms, that is what somebody had told me. Thanks again.

With Regards
Anoop.

I've got a little problem, i've got one threaded class setting up all parameters and finially showing a MSN-Lookalike PopUp window, with a sliding effect. the problem is, the popup only slides 1 or 2px then it gets stuck. Calling the function within the class without using a thread causes no problem and it's shown as it's supposed to. Could anyone help me out or give me a hint ? please Blush | :O

class PopUpHandler<br />
{<br />
private string popTitle;<br />
private string popContent;<br />
TaskbarNotifier taskbarNotifier;<br />
public PopUpHandler(string strTitle, string strContent)<br />
{<br />
popTitle = strTitle;<br />
popContent = strContent;<br />
Thread popUpThread = new Thread(new ThreadStart(popupShowMessage));<br />
popUpThread.Start();<br />
}<br />
public void popupShowMessage() // A function to show a PopUp (MSN-Lookalike)<br />
{<br />
// Gets a reference to the same assembly that contains the type that is creating the ResourceManager.<br />
System.Reflection.Assembly myAssembly = this.GetType().Assembly;<br />
<br />
// Creates the ResourceManager.<br />
ResourceManager myManager = new ResourceManager("SystemTray.Form1", myAssembly);<br />
<br />
// All parameters for the PopUp<br />
taskbarNotifier = new TaskbarNotifier();<br />
taskbarNotifier.SetBackgroundBitmap((Bitmap)Properties.Resources.imageSkin, Color.FromArgb(255, 0, 255));<br />
taskbarNotifier.SetCloseBitmap((Bitmap)Properties.Resources.imageClose, Color.FromArgb(255, 0, 255), new Point(127, 8));<br />
taskbarNotifier.TitleRectangle = new Rectangle(40, 9, 80, 25);<br />
taskbarNotifier.ContentRectangle = new Rectangle(8, 41, 133, 68);<br />
//taskbarNotifier.TitleClick += new EventHandler(TitleClick);<br />
//taskbarNotifier.ContentClick += new EventHandler(ContentClick);<br />
//taskbarNotifier.CloseClick += new EventHandler(CloseClick);<br />
taskbarNotifier.Show(popTitle, popContent, 500, 4000, 50);<br />
}<br />
}

I want to create an object. Its background is transparent (it shows underground object). And it shows any Text like Label Control.

How can i do it?

Derive a class from Label. Put this in the constructor:

SetStyle(ControlStyles.UserPaint | ControlStyles.DoubleBuffer | ControlStyles.AllPaintingInWmPaint | ControlStyles.SupportsTransparentBackColor, true);

You can set the background to Color.Transparent if you like, but it doesn't matter. If you write a Paint handler that renders the text only, you'll have what you want.

If you want a whole form to be transparent (but not its content) you could set its transperency key to a color you will NEVER use for anything else but the forms background color.

<br />
this.BackColor = Color.FromArgb(255,2,3,4);<br />
this.TransparencyKey = Color.FromArgb(255,2,3,4);<br />

this would make the form invisible.
To create transperent controls see the comment before this one Smile | :)

I create a picture. It has an image. And i put a label on it. I want the backcolor of the label is invisible. It shows only text.

In Vb 6.0, i can do it. If i set the label's backcolor is transparent. It doesn't show the backcolor.

Your response doesn't do what i want

i understood you correctly. i told you to have a look for the former comment on how to make CONTROLS (like your label) transparent. you have to derive it, add a function call to the constructor and override the onpaint method of the base class.

Dear mikone
Whould you please write a sample code about Transparenting Label and overwriting OnPaint

Hi Dear programs..

how can i save utf-8 format characters to database

for example
تا زا
saved to data base

and when recieved i get ???????
which class encode it and decode it

sikandar

Keep it in the same thread instead of starting another.

---
b { font-weight: normal; }

You should choose Type of fields in database "nVarchar Or ntext".

You should choose Type of fields in database "nVarchar Or ntext".

this is not working

Hi,

New to the forum, and new to C#, so apologies for appearing a bit, er new to all of this!

I have a large CSV file that I want breaking down into smaller ones. So if I have, say 1500 records in it, I want it split up per 1000, i.e. the first CSV file will have 1000 records in and the second one has 500. I've tried searching for this and can find a few examples of reading CSV files (not that I understand many of them!), but can't seem to find anything that does what I want. Can anybody help me please?

Thank you to anyone who does.

Something that might make this clearer:

I guess if I could read the files I could do a for-loop to check how many records there were, then save to a new file once it reaches 1000. So I'm not sure about reading them and don't know how to output them to a file. Hope this helps!

a CSV file is just plain text (open one in Notepad to see), so all you need to do is read the text file, and dump out the lines to new files

pseudocode:

OPEN input.csv
OPEN output1.csv
OPEN output2.csv
  // read the header line from the input CSV and store that in the outputs
  header = input.GETLINE
  output1.WRITELINE(header)
  output2.WRITELINE(header)
  
  line = 0;
  WHILE ( line < 1000 & !input.EOF )
    row = input.GETLINE
    output1.WRITELINE(row)
    line++
  ENDWHILE
 
  output1.CLOSE

  WHILE( !input.EOF )
    row = input.getline
    output2.WRITELINE(row)
  ENDWHILE

  output2.CLOSE

input.CLOSE

Buzzwords!

There is one exception: CSV doesnt say ANYTHING about whats in there. So, there actually might be headers in the first line of the file.

If thats the case, you will want to read the first line seperately, store it, and write it to ALL output files before starting to distribute the other entries.

Cheers,
Sebastian

Thanks for your help benjymous.

I have tried working through this, but no success yet; I know it is a basic thing I am missing, but not sure what. The code I have so far is:

using System;
using System.Collections;
using System.IO;
using System.Text;

public class CSVReader
{
// Open the files to write to
string fileName = @"C:\data\Test Data\Test\CIS_KASN.txt";
string textLine;
int row = 1;
}

public CSVReader(string fileName)
{
StreamReader fileReader = File.OpenText(fileName);
StreamWriter fileWriter1 = File.CreateText(@"C:data\Test Data\Test\Output1 CIS_KASN.txt");
StreamWriter fileWriter2 = File.CreateText(@"C:data\Test Data\Test\Output2 CIS_KASN.txt");

while ((textLine = fileReader.ReadLine()) != null && row <= 1000)
{
// Write to output file
fileWriter1.WriteLine(textLine);
row++;
}

fileWriter1.Close();

while ((textLine = fileReader.ReadLine()) != null & row > 1000)
{
// Write to output file
fileWriter2.WriteLine(textLine);
}

fileWriter2.Close();
}

Does this make much sense?

Also, point taken about the header; I'll work that part out when I get the main part working!

Thanks all.

I'm just curious what is the root cause of having to break up the CSV?

Another programme has been written that only allows CSV files of 1000 records per go. I don't know what it's been written in etc, but suffice to say it will take a long time for that side of things to be changed; this is seen as quicker. So any help is much appreciated!
