am trying to load data from an excel worksheet & its really giving me headache. A particular column contains both string and numeric data. its picking only the numeric data & loading the string data as blank entries. I tried checking what may be wrong, i think i saw a documentation that says Excel scans the first 8 rows of a column & determines it data type.plz, how can i load everything on the sheet (i can get everything as string, but i dont want to lose any entry)

I have an web application of 200 web pages and all has a single master page. Most of the content pages use AJAX controls so most of content pages has its own ScriptManager. Now I have a requirement to add a link with HoverMenuExtender control and for that I need to put ScriptManager in the Master page, but it is working only in the content pages where there is not ScriptManager.

In my app I have a main form listing basic customer info in a datagridview. When the user single-clicks a customer, I want all the customers info to appear on the right side of the main form for viewing/editing/deleting, etc. Also, if the user double-clicks a customer I want a new form to appear (not an MDI child, but an external form) to appear with the same info for viewing/editing/deleting, etc. (Kind of like MS Outlook where you can open an item in the main Outlook window or externally).Since the external form and the right side of the main form need to show the same info and have the same functionality, I created a User Control to house all the customers detail controls and the ability to edit or delete.
Questions: Is using a User Control the best way to go?
The customer data on the main form is brought in via dataset, tableadapter and bindingsource. When a user single or double clicks a customer, that customers ID needs to get to the details User Control, regardless of whether it's in the main form or external form. What's the best way to get that customer ID to the User Control? Or should the main form "pass" the data binding source to the User Control?Once the customer ID has been received in the User Control, what's the best way to show that customer's details and prepare it for editing?

I have the following code that creates a master/detail scenario between a products table and a test table based on the productid: [code]Unhandled exception has occured. the constraint cannot be enabled as not all values have corresponding parent values as you will see, where I add the datarelation between the two datatables i've added a false. This ensures constraints are not created.That solved the problem. However, I want to know if this is the correct solution. It is really difficult to troubleshoot as I cannot reproduce the error. The database is accessed through the network. it could be the network was down at the time so the child records where not inserted hence the error.

In it's simplest form, I have two forms a master form and a detail form. I added the data source from within the ide.
Data> add new data source database>new connection > microsoft sql server database file. Selected table etc.
From the datasources tab in the ide I dragged the grid view onto the master form. dragged the detail view onto the details form.Independently both forms work fine, However if I load the master form first and then load the detail form when the master dgv is clicked the problems start.
[code]...
All variables are correctly declared and the details form works fine, the correct record comes up and can be added, edited and deleted.I then save the form by clicking on the save icon and close the form but changes made to the details form (e.g. additions or deletions) are NOT reflected on the master form until I close and rerun the application. guess it's just a matter of refreshing the right control(s) on the master form but I cant seem to find it.

I have a nested master page that has its own master page. The parent master page has a property defined in its code behind.
Public ReadOnly Property SelectedPage() As String
Get
Return _selectedPage
End Get
End Property
How can I reference the parent master page's property from within either the child master page's code behind Page_Load or aspx template page?

I am using a DLL in my application that will probably be experiencing frequent updates. I want the DLL to detect the new version (I know how to do this), load the new version of the DLL into memory, and continue running. Is this even possible? So I need to know how to: Unload the current DLL. Load the new DLL. If possible, do this from the DLL in question. Is this even possible? If not, how close can I get to this?

I've got a database that's 13,000 lines long and I'm trying to load this into a string array when the program loads but it takes approx 5-6 minutes for it to load it.I've got a MS Access database or an Excel file that I can load this information from, each has two rows: SVONo, Description This is my current MS Access
[code]...
Does anyone have any idea of how to make it faster? Or does anyone have a better way?I did have the idea of loading it by letting the user select the first letter and then only loading the ones that begin with that letter but I've got 4000-5000 'S' ones and it still takes about 2-3 minutes to load it All I want is to load the data from the database or the excel file and then put the products into 'cboProducts' and the 'cboProducts AutoCompleSourceList' and the descriptions into the 'txtDescriptions' AutoCompleteSourceList and a string array.Then when the user selects a product using 'cboProducts' the description will automatically be put into 'txtDescription'.

I am doing a project for part of my coursework which involves the creation of a series circuit designer.
I am having some trouble with the saving and loading functions; I had intended to save them to a text file with commas separating the component name and the value (if any) attributed with it.
Grid(xcoord, ycoord, 0) contains the component name. Grid(xcoord, ycoord, 1) contains the attached value (resistance or voltage- components such as wires have a value here of 0)
Once the save button is pressed, the text file contains 50 rows of "0".
P.S. Let me know if any other parts of my program are required.

Const maxsize = 50

I have a desktop application that shows a list of pdfs, and when the user selects one it shows it to him/her. I use the AcroPDF control for this, and it seems to work, but if the user goes back and forth between viewing the file and viewing the list, then the control randomly decides not to show the file (showing a blank page instead).

I am currently developing an application that will be the "base" for several components (business reporting systems, order management, etc). The idea is that our customers will install this "mother application", and we will offer components that will slot into it, expanding the functionality.
Now, here's my idea for how to make this work. I have some of this basic functionality down, but I want to get other people's opinions, ideas and experiences with this sort of thing before I move too far in a direction that might not be the best way to go:
