MS Access itself limits the 'char' data type to 255 characters.
To "pour' the data from excel to MS Access you must be using some sort of conversion. If the conversion only allows for 'char' or if you explicitly set it to 'char' then it will only move 255 characters.

And yet he specifically noted that the actual process was producing only and exactly 255 characters.
I was suggesting that the evidence strongly suggested that the conversion process was not in fact using Memo but Char. So something in the steps, presumably multiple, that comprise the entire process was introducing Char.

Hello first time poster, so thanks for any help.
what I'm attempting to do is read a text file that consists of one row of numbers then a space and then a row of names, what I need to do is first read the numbers in the row save them to an int and then read the names and save to string. so i can loop them and compare information.
heres a sameple

Two ways:
1) Use an IndexOf and SubString:
int space = input.IndexOf(' ');
string intPart = input.Substring(0, space);
string strPart = input.Substring(space);
2) Use a regex to separate them:
Match m = Regex.Match(input, @"^(?<int>\d+)\s(?<str>.*)$");
if (m.Success)
{
string intPart = m.Groups["int"].Value;
string strPart = m.Groups["str"].Value;
}
You can then use int.TryParse to convert the number part to an int.

Hi...I really need help for a runtime bug.
I have made a custom panel and custom textbox with some properties and one method.
Both Classes(panel and textbox) have one public method called AddMe, witch will add panel to the splitcontainer on form1 and textbox on panel.
My problem is that, at first it worked just fine, panel was added to the splitcontainer and textbox was added to panel. But after i added a second textbox witch also was gonna be added to panel, then the first textbox wont show anymore, nor the the second textbox. I did´nt make the big change on the code. I try to remove the referrence to the second textbox, but nothing helped.
Hope anyone can help...Best regards...
Here is the sourecode...
private void InitializeInputPanel()
{
InputPanel.Width = PnlWidth;
InputPanel.Height = Pnlheight;
InputPanel.BackColor = pnlbackgroundcolor;
InputPanel.BorderStyle = Pnlborderstyle;
InputPanel.Font = Pnlfont;
InputPanel.Dock = Pnldockstyle;
InputPanel.Location = PnlPoint;
InpbBeskrivelseTxtBox inpb = new InpbBeskrivelseTxtBox();
inpb.AddMe(InputPanel);
}
class InpbBeskrivelseTxtBox
{
TextBox BeskrivelseTextBox =new TextBox();

Hi,
your code is pretty weird. I'll skip many details, and make only a few remarks.
1.
For one, InpbBeskrivelseTxtBox is not a TextBox, it isn't even a Control. Yes, it has a field that holds a TextBox, but that does not turn it into a TextBox.
Therefore
control.Controls.Add(BeskrivelseTextBox); will never succeed, as the AddMe() method expects a Control. So I guess your code won't compile.
What you really want is have class InpbBeskrivelseTxtBox implement a TextBox, a specialized one.
So you should start off with
class InpbBeskrivelseTxtBox : TextBox {...} and remove the TextBox field inside that class; the class itself now is a TextBox, which you can add to a parent Control.
When you do this, InpbBeskrivelseTxtBox automatically inherits all the Properties a TextBox has, so you'll have to organize your initialisation a bit differently, and maybe assign appropriate values in the constructor.
Custom Control: Numeric TextBox: TextBox that alow you to enter only numbers[^] is a short CodeProject article that demonstrates how things could be done. I would suggest you read it.
2.
If you are new to Windows user interface programming, I'd recommend buying and studying a book on the matter, most any C# book should do. Learning from a book may seem a slow process, but trust me it is the fastest way to get acquainted with the proper way of doing things.
3.
Visual Studio offers a choice what to do when compile errors occur; one option is to run the previous version, it once was the default, maybe it still is, I don't know. This is very bad, as it executes an exe that does not match your current source files. Look for the option (probably menu Tools/Options/Projects and Solutions/Build and Run/On Run when errors occur), and make sure it is set to "Do not launch". That will avoid lots of grief, enforcing compilable source code before you can even attempt to run or debug.

Just to add to Luc's excellent and comprehensive answer.
I'd be a little wary of a control method that adds that control instance to a specific form - from a OOPs point of view that is very wrong: a control should not need to know about it's container as that restricts it's usability. Plus there is the fun and games of working out which Form1 instance it is supposed to be attached to...
A Form should add it's Controls, not the other way around.

You could've just passed a reference to the "text box"; instead of duplicating every property.

I want to read the text file on a specific line and perform a task according to the information.
example: I have a string with the value ON, in case the program will read the text file online, if you have the information ON on line 4 performs a task, if OFF accomplishes another task can anyone help me?
|
|
|
|
|
With what part of this? What do you mean by "online"?
|
|
|
|
|
Text files don't have "lines" - they are just a stream of characters, where a specific character (or pair of characters, it's OS dependant) are interpreted by some functions as an "End of Line" character.
As such, the only ways to find "line 4" are to:
1) Read the whole text into a string and scan it for '\n' characters yourself.
2) Use the ReadLine methods provided with text streams to skip lines 1 to 3.
3) Read the whole text into an array of strings using the File.ReadAllLines method, and access each line via the array index.
But ... You are talking about "online" so it gets more complex: you can only read the file if you have access to it, and that means pretty much only on the computer that the software is running on. For C# in a website, that means the server not the client - C# does not run on the client at all, and server code has no direct access to client files.
You may have to bear this in mind when you design your system, as it will probably work in development (where the client and the server are the same physical computer) but fail spectacularly in production.

Hi, My name is Wish and I have recently coded an application that recognizes commands I ask it to do(open notepad, gives time, etc.) I now want to be able to ask it a question like "who is Barack Obama" and it will respond with the first paragraph of the wikipedia article.
I have this code so far which requires me to manually type in what I want to search for.
This is that code
<pre> var webClient = new WebClient();
var pageSC = webClient.DownloadString("http://en.wikipedia.org/w/api.php?format=xml&action=query&prop=extracts&titles=" + textBox1.Text + "&redirects=true");
XmlDocument doc = new XmlDocument();
doc.LoadXml(pageSC);
var fnode = doc.GetElementsByTagName("extract")[0];
try
{
string ss = fnode.InnerText;
Regex regex = new Regex("\\<[^\\>]*\\>");
string.Format("Before:{0}", ss);
ss = regex.Replace(ss, string.Empty);
string result = String.Format(ss);
richTextBox2.Text = result;
}
catch
{
richTextBox2.Text = "error";
}
Any and all help will be greatly appreciated.
If this is too vauge of a question please tell me and I will try to explain in more detail.
Thanks,
Wish

You haven't really said what the problem is that you are facing. I assume that the issue you are having is that you don't know how to do the voice recognition part. Would that be a fair assumption?

yeah thats basically it..

What are you using for recognizing spoken commands? If it is the MS-agent technology, then it will not accept words that are not defined as a command.

Download the article into a stream, identify the first paragraph and feed that to the TTS engine.

Instead using `XmlDocument` use AngelSharp library to parse the HTML and extract first paragraph.

I have a Yaxis_bufferList, which gets updated with new data. My Xaxis_bufferList is fixed and always contains same values.
I need to plot these values on a graph. whenever i plot the new graph, the previous graph is lost. how do i retain the data? How do i plot all the graphs.
|
|
|
|
|
How are you plotting them now?
There are many ways to plot graphs, and some depend on the environment you are working in - so explain where you are and show us the relevant code fragments.
