Try this: [code] using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace daniweb { public partial class frmGridView2 : Form { DataTable dt; private TextBox editingBox; //I cant find where the gridView holds the reference public frmGridView2() { InitializeComponent(); editingBox = default(TextBox); …

Is the input fixed at all? You could use a MaskedTextBox and set the mask to a numeric mask. There is also a numeric control you could use: [url]http://www.codeproject.com/KB/edit/TNumEditBox.aspx[/url]

Please use code tags in the future [code = VB.NET] <- Remove the spaces and it will work code here [/code] To answer your question you should move the functionality to another method instead of calling the button's click event, but: [code=vb.net] Private Sub Button1_Click(ByVal sender As System.Object, ByVal e …

That is not enough information. You can use the import/export wizard built in the SQL Server Management studio. Excel has a limit ~65535 if i recall correctly (may be more in the newer version) so you might not be able to export all of your data. Also do you want …

Post the [icode]CREATE TABLE[/icode] SQL for you Customer table. Is the CustomerId an integral field?

[QUOTE=phalaris_trip;928954] I wonder if there's a way to force the OS to invalidate or something...[/QUOTE] Invalidate just causes the invalidated region of the screen/form to be redrawn. You need explorer to truly do a refresh of the data subset to display the files.

I agree! :)

Look at the output window after you click the button. Do you see an exception similar to: [code]A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll[/code]

You can use a one-liner ;) [code] textBox1.Enabled = checkBox1.Checked; [/code] DIPY -- Are you getting a callstack overflow error? I'm looking at the code you pasted and in the event you are changing the check status of the checkbox that fired the event. [code] public void Checked_Changed(Object sender, EventArgs …

This should do the trick for you. [code=csharp] private void frmGridView_Load(object sender, EventArgs e) { this.customerTableAdapter.Fill(this.dataSet1.Customer); } private void button1_Click(object sender, EventArgs e) { DataSet ds = new DataSet(); DataTable dt = new DataTable(); dt.TableName = "MyTable"; foreach (DataGridViewColumn col in dataGridView1.Columns) { dt.Columns.Add(col.DataPropertyName, col.ValueType); } foreach (DataGridViewRow gridRow in …

The above answers are 'technically' incorrect (but deceptikon did a great job explaining it). Exceptions are very expensive to be thrown, but are of little cost to be caught (not no cost). This is especially noticeable if they are thrown in code that is commonly called (painting, calculations, etc). try..catch{} …

Try this: [code] using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace daniweb.mdi { public partial class frmMain : Form { public frmMain() { InitializeComponent(); } private Form OpenForm(Type t) { if (!t.IsSubclassOf(typeof(Form)) && !(t == typeof(Form))) throw new ArgumentException("Type is not …

I suppose it may be possible for `cert.SubjectName` to be null or `cert.SubjectName.Name` to be null. Also this part is incorrect: catch (Exception e) { throw e; } When you do that it re-throws the exception with new line numbers -- thus makes harder chasing down the actual problem. There …

Try doing a [icode]chmod -R 744 <dir>[/icode] on the directory. You will need to clean up the perms after you run that command. A directory in *nix needs the +x in order for you to "cd" in to it. [code=bash] sk@sk:/tmp/x$ ls -al total 9 drwxr--r-- 2 sk wheel 1024 …

I think this is what you want. Hard to say without the table structures or an accurate description. [code=sql] Select ID, Name, ( Select Sum(Points) From Table2 Where Table2.ID = Table1.ID ) As Total From Table1 Where ID >= 1 and ID <= 3 Order By ID [/code]

[QUOTE=dnanetwork;918412]use application variable....works... 100%[/QUOTE] Application variables are not persisted and you will lose the count data.

You should be using parameterized SQL. Its a lot easier to read queries and ensure you're not having datatype mismatches. [code] Imports System.Data.SqlClient Imports System.Text Public Class Form1 'Create Table TestTable '( ' Column1 varchar(100) PRIMARY KEY NOT NULL ') Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click …

What are you trying to do? Normally with a ping its along the lines of "are you there (echo request)?. Yes I am (echo response)." You normally don't want to populate any sort of buffer with pings (ICMP) unless you have a specific purpose for doing so. As far as …

Here are some network extensions that should help you out: [code=c#] static IEnumerable<UnicastIPAddressInformation> GetLocalIPv4Bindings() { NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces(); foreach (NetworkInterface ni in interfaces) { IPInterfaceProperties props; try { props = ni.GetIPProperties(); } catch { continue; } for (int i1 = 0; i1 < props.UnicastAddresses.Count; i1++) { if (props.UnicastAddresses[i1].Address.AddressFamily == …

No. Columns depend entirely on the resultant dataset.

Well it depends on how you want the scripts to interact with eachother. If you want to share environment variables that have not been exported then you would call the file with [icode]. /path/to/file.sh[/icode] or [icode]source /path/to/file.sh[/icode]. If you don't want to share the environment of the script you would …

You may also consider using [icode]Regex.Split()[/icode] to split on word boundaries and filter out the punctuation.

I think you are referring to the difference between encapsulation vs inheritence. They are well documented topics on the net so look up a few articles and see if that answers your question. If not post then please post back.

Taking a step back -- what exactly are you trying to do here? If you want absolute performance than managed code is not the answer. The ability to control struct layouts is present for interop reasons. For example see [URL="http://www.daniweb.com/software-development/csharp/threads/370676"]this thread[/URL]. You can instantiate structs faster than classes sure but …

The "attachment" in your content-disposition instructs the browser to prompt for saving. The desired behavior you're describing is inline: [code=c#] if (view) Response.AddHeader("Content-Disposition", "inline; filename = " + file.OriginalFileName); else Response.AddHeader("Content-Disposition", "attachment; filename = " + file.OriginalFileName); [/code]

Here is how I handle reading masked bits: [code] public static class BITS { public const byte BIT0 = 0x01; public const byte BIT1 = 0x02; public const byte BIT2 = 0x04; public const byte BIT3 = 0x08; public const byte BIT4 = 0x10; public const byte BIT5 = 0x20; …

This is commonly referred to as a pivot.

Group by every column you select. If the duplicates are somehow coming from a join it will still be eliminated in a group by.

I think you may mean FFF0 is hex. If so that is 2 bytes (32-bit). Other than that I can't really make sense of your question.

Those two metrics are not necessarily related. Ping is round-trip latency, ie "it takes 300ms to send a packet then receive a response from the host". As you begin downloading it increases congestion on the line and results and in higher packet round-trip times. This is probably a question of …
