Secondly, you are inserting the values if dr.HasRows == true. This should be the other way around. If dr.HasRows is true then it means the user was found in the database and …

The problem here is that the '' character is the escape symbol for both C# [B]and[/B] WQL. Using '@' tells C# not to escape the '' but you need to tell WQL the same thing. Heres an example to try and clear it up: You enter "WHERE Drive = 'C:' …

Not the source of your problem, but you are using sender.ToString(). For controls that usually returns something like "System.Windows.Forms.TextBox, Text: <textbox.text here>". Its not in your code, but im assuming textbox is a class level variable to store a reference to the textbox, you should use textbox.Text to get the …

As adatapost says, you can use a boolean array to mark the seats as dirty. As for finding the best match location for the group, one way would be to find all suitable locations for each person, then find all combinations of those possibilities. Then for each combination you can …

The problem you are going to face is that the datagridview (dgv) combobox column is not a regular combobox. Usually you can use the OnDropDown event to show a form with your table in it. But the dgv version doesnt fire these events. One option would be to use the …

Another option would be to use a grid of controls, such as pictureboxes. Use a simple algorythm that calculates the correct size for each based on the number per row/column and the form size then use a loop to draw them to the form. I did something similar a few …

The TargetInvocationException tells you that the method you are calling has thrown an exception. Check the InnerException property of the exception to find out what the underlying cause might have been.

Whilst flicking through someones profile, i noticed something odd. They have a reputation of 11, 213 posts, 64% quality, 6 solved threads...and they can give +3 to someones rep. I understand that the rep power is calculated on a number of things, but i have 609 posts, 92% quality, 126 …

You need to ensure that the MDI Child has a method called NewButton and that the method is declared as Public.

generally it helps to try and model the rela world example first. So, sit down and work out what attributes each part of the model needs to have. I'm guessing you are trying to write a program to deal with a race course of some sort..i'd start somewhere like: [U]Race …

I think you ought to reconsider regex. It is a very powerful tool and its not that difficult to pick up the basics. You can use it to check for incorrect characters as well as specific patterns...which is vrey handy for validating things like postcode/email address/telephone number etc. We'd be …

Also, the standard event handler has two parameters, sender and eventArgs. sender will contain a reference to the control that fired the event. You need to cast it back to its correct type to access its members though: [CODE] private void Panel1_Click(object sender, EventArgs e) { Panel clicked = (Panel)sender; …

I'm not sure what was wrong with your timer corey, i dropped on onto a form with two buttons and a textbox and the following code worked fine: [CODE] public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void btnStart_Click(object sender, EventArgs e) { timer1.Interval = …

You will have some new errors when you fix this problem. Your error is a result of calling a variable you havent declared (as Cory_Brown correctly pointed out) but you are also making inter-thread calls which will throw errors. You can't access variables/controls in your main form from a new …

Have you checked that each of your controls is returning a valid value? eg, com_cname.SelectedValue is set and correctly formatted, etc.

When it logs in does it have write permission via the API or does it just retrieve the documents?

i have a similar setup in one of my apps. I'm not sure why you can't alter the values, i have no problems. I use the RowsAdded event to set the images and apply any styling to the rows: [CODE] private void dgvOrders_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e) { for (int i …

Firstly, its [icode]*code here*[/icode] for inline code :) Secondly, the `(Excel.Application)` is a [cast](http://msdn.microsoft.com/en-us/library/ms173105(VS.80).aspx).

use int.tryparse: [CODE] int userInput; if(int.TryParse(Console.ReadLine(), out userInput) { //input was valid } else { //error...non int value } [/CODE] TryParse accepts two parameters: string to parse, variable to store result in (reference by the 'out' keyword). It returns a boolean value to say wether it succeeded.

I know this has been marked as solved, but thought i'd chime in. The reason that you are getting random numbers when you generate them at the same time you declare the array is that you are using a single instance of the Random class. You have declared one RandNum …

You dont need to use the string.Repalce method. you can split using the '' character, just double it up to escape it: [CODE] string path = @"C:\test\name.txt"; char[] splitchar = {'\'}; string[] nameParts = path.Split(splitchar); [/CODE]

I assume you are putting the code in the textboxes TextChanged event. You are checking if the max length of the textbox is less than 10. What you need to do is check if the length of the text entered is greater than the max length: [CODE] if (txtCustName.Text.Length > …

As jonsca said, we'd need to see a larger code section to be sure, but it looks like you have overridden the ToString method of the Rectangle Class but are calling .ToString on the collection of rectangles. You would need something like: [CODE] Rectangle [] rects = new Rectangle[5]; string …

If you are using tableadapters, i would recommend adding your own delete query. The standard ones are pretty heavy going, you have to put the value for every single column.

I'm not sure if theres a built in way of doing it...but you could simulate it; Use the RowSelected event to change the background of the row to maintain the selected colour when the datagridview loses focus. Then each time a row is clicked use a List to store a …

Wow, ncie code apegram :) deathtoall141, are you copying apegrams code exactly? The code he gave you is a Console Application intended as an example. You will need to make a few changes to run it on a button click. Firstly, ensure you have correctly created your buttonclick event handler. …

Whilst farooqaaa's code might get it done, its cleaner to use the ItemCheck event instead.

I'm not sure your code will work. The Convert.ToString function works differently with ListviewItem and ListboxItem. You would get something like: Convert.ToString(menuList.SelectedItem) = "FoodA" Convert.ToString(orderList.FindItemWithText(currentItem)) = "ListViewItem: {FoodA}" FindItemWithText returns a ListViewItem, which has an Index property. I would use something like this: [CODE] private void menuList_SelectedIndexChanged(object sender, EventArgs e) …

totally agree with apegram. When accepting user input you should always validate it. FOr instance, your first question will output an answer if they enter an uppercase Y or uppercase N. If they enter a lowercase Y/N or a letter other than Y/N it will skip over the rest of …
