BindingNavigator And Bindingsource Control?
Feb 5, 2009I have one datagridview control, a BindingNavigation and a Binding control on my form. I populate the datagridview control through the code. Moreover, the datasource properties of the DatagridView and the Binding controls are assigned a value through code (I didn't specify anyting in the properties window). The same for the bindingsource property of the BindingNavigation control (I assign a value trhough code). My code is the following:
[Code]...
This code brings and shows the right results in the datagridview control, but the navigator control is inactive. I know that I have to bind the controls(DataGridView + BindingNavigator) to the BindingSource control. Is this a problem that I tried to do this by coding?

BindingNavigator Connected To BindingSource That Connects To An Access Database And SQL Insert
Apr 5, 2010I have a windows app that has a bindingNavigator connected to BindingSource that connects to an Access database. I am manually adding a record to the underlying database using an OLEDBConnection/command (cloning the current record). The insert into the database works fine, what I am not sure on how to do is force the bindingNavigatgor to refresh and read the new record and refelect it in the record count/next/previous buttons.Jack

The name it picks "xxxxxtableadapter", "xxxxxbindingsource", and "xxxxxbindingnavigator", where "xxxxx" is the tablename, is in my opinion a bit wordy.

User Validation - .add And .invoke Being Ran asynchronously And Occasionally Causing Errors?
Sep 2, 2011I have a bit of code that jumps around a few domains and adds a user to each of them. This follow is a piece of code I had to write to get around the issue of the .add and .invoke being ran asynchronously and occasionally causing errors.
It connects to the domain in question, passing a "CN" from the code in as a search filter but receives a COMException which is normally a LDAP sting config issue. The connection string in this is fine so I am not sure why it is having such a hard time.

Errors When Calculating - Doesn't Calculate Anything Correctly ?
Sep 9, 2009I am making this program for a school assignment but it has errors when calculating
Private Sub frmReceipt_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'When this form is loaded, assign the date to the date label & start the timer
lblDate.Text = Date.Now
[CODE]...
So if counter finishes, execute the following code
If counter > 4 And km >= 1 And kmcashset = 0 Then 'If there is still kms to calculate 'And kmcashset = 0
kmcashholder = kmcash
km = km / 5
[CODE]...
And if I add counter = 0 and km = 0 at the end of that "If counter > 4 And km >= 1 And kmcashset = 0" Then it doesn't calculate anything correctly. I supply it with 9 for Distance and it returns 4 for excessdistance which is correct but returns 7 for excessdistancecharge when it should be 4! When I supply 23 for Distance it returns 18 for excessdistance and 11 for excess distance charge which is correct. (???)
Excessweightcharge calculates correctly.
I think it may be the way I'm implementing it, through the use of AND or maybe it's because it's in timer tick?
-Minimum charge of $5 which covers 10 kgs for the first 5 kms only
-Each kg over 10 kgs incurs a charge of $0.50
-Distances over 5 kms incur an additional charge of $1 per km up to 10 kms
-For deliveries over 10 kms, the extra distance should be rounded up to the nearest 5 kms and charged at $2 for each extra 5 km block.
EXAMPLE 1:
Packet weighing 9kms travelling 9 kms
Standard charge for first 5 kms ($5.00)
Weight less than 10 kgs so no extra weight charge
Extra distance charge 9 - 5 kms = 4kms x $1 = ($4)
Total delivery charge = $5 plus $4 = $9
[But my program returns 7 for excess distance charge]
EXAMPLE 2:
Packet weighing 33kgs travelling 23 kms
Standard charge for the first 5 kms ($5)
Excess weight 33 - 10 kgs = 23kgs x $0.50 ($11.50)
Extra distance (23 - 5kms = 18kms):
18kms ( 5 to 10 kms at $1/km) = ($5)
13kms (18-5)/5 = 3 (rounded up) x $2.00 = ($6)
$5 + $6 = $11
Total delivery charge = $5 plus $11.50 plus $11 = $27.50
[My program calculates everything correctly]

View 2 RepliesASP.NET UpdatePanel Timeout And 500 Errors With Custom Errors?
Sep 23, 2011I have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?
Below is my code to give you an idea, not exactly what I have in my application but pretty close.
Web.Config
<customErrors mode="On" defaultRedirect="~/Errors/ErrorUnknown.aspx" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="~/Errors/Error500.aspx" />

Interface And Graphics :: Top / Left Positioning Options
May 27, 2009I have a system that has a collection of picture boxes.Each picture box allows you to place pointers(Custom control derived from label) on the image, when saved I store the X/Y for the pointers along with other information relevant to the pointers in a database.(See attached image)This way the chart can be reloaded and the pointers be moved or edited.This all works great until I resize a chart, the calculated percentage of size in/decrease often results in a float like in the following example. [code] I position the pointers by top and left, which only accepts integer, the rounding results in significant drift over multiple resizes.

VS 2010 Positioning PictureBoxes Inside TabPages?
Aug 16, 2011I have a series of tabs, each containing a series programatically generated PictureBoxes that are all 480x360. The TabControl is anchored to all 4 edges of the form, so it always takes up the whole area.
I would like the PictureBoxes to behave similarly to how images behave when floated in HTML/CSS. So if I have 5 pictures and the window is only ~900 wide then I will have 3 rows, 2 in the first 2 and 1 in the last. But if the window is then expanded to ~1500 then I get 2 rows - 3 on the first and 2 on the last.
What is the simplest way to achieve this? Is there a built in way?I am planning on repositioning the pictures when SizeChanged fires on the TabControl, or when the selected tab changes.

BindingNavigator In TabControl?
Apr 16, 2009I have a tab control with several pages. Within a page I have a panel. When I drag and drop a database to the panel the datagrid view is placed on the panel, but the bindingnavigator is placed outside the tabcontrol. Running the application shows only the bindingnavigator, which seems to have blocked the tabcontrol. If I cut and paste the bindingnavigator to the panel, and running the application shows the page with the bindingnavigator at the top and the datagrid below. However, the bindingnavigator no longer allows me to add and save entries to the database. I made sure all the properties were the same before and after i cut and pasted the binding navigator.As a test, I removed the tabcontrol, dragged and dropped the database to the empty form, and everything worked.
