What parameters do I pass to a Button Click Event. I just want to call a Button Click event from a TextBox. The only reason I'm doing this is so I don't have to repeat the code that is in the Button Click Event. I'm calling this Event from a KeyDown Event of a textbox.

with a better solution.I have a .NET method that takes in 20+ boolean values, passed in individually.For each parameter that is true I need to add a value to list. Is there a more efficient way to add the values to the list besides have an if statement for each boolean?
Example:
Public Function Example(ByVal pblnBool1 as boolean, _
ByVal pblnBool2 as boolean, _

I want to pass a List of T where T is an object I've created that has about ten properties (strings, dates and integers).The lst passes to the function successfully. I am also passing an New T of the Object (itm as T).I can see all the values (see image below), but because it's generic I cannot seem to retrieve the property values and I cannot figure out how to iterate through the properties of each itm as they are retrieved in the For Each.[code]

I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

Basically Commands has Parameters and parameters has functions like Add, AddWithValue, and etc. In all tutorials i've seen, i usually noticed that they are using Add instead of AddWithValue.

View 3 RepliesI'm very new to vbs scripting and am trying to set a System envinonment variable which will be used by a subsequent cmd file which is called by the VBS script which created the ENV varible.The vbs script creates the varibale correctly but the called CMD file does not find it. I thought a child process inherited its parent env settings. I understand the child can not change the parents env. why the cmd file does not see the variable, am I using the wrong shell command in vbs to call the cmd file or something?Here is the VBS script that simply sets a System varibale and the CMD file below which attempts to log it.on error resume next

View 1 RepliesOk so I tried to make an application that will open a URL ONLY if 24hours has passed since it had previously opened. My idea is that it will save the time/date to a .txt (unless there another way which im completely missing?) when it is opened (only open if the current time is the saved time/date + 24hours) and rewrite it after every time.
When I say I tried, I mean I opened a project, realised I had no idea what to do and stared at the Form for 10minutes.
I have kind of a problem in a database well its suppose to save a date but like a string, well more like a char type, and i need it that way to do reports.So there to tables Ventas and VentasDD so they have the same information what ever is introduced in the form both those tables have the information, the information is introduced simultaneously.So this is how its supposed to be save like VENTAS image the VENTAS date is saved correctly But the when its saved on VENTASDD table the format for some reason changes even if its the same type and text and everything, like the image shows, the first record i modified it manually but it is displayed like the other 3 records

I have a form with its method being "get" that passes the variables and their values to the query string, respectively. However, it also passes the viewstate variable in the query string. Now, I have a very long viewstate value on the given page, and if passed in the query string, the viewstate variable will cause the page to error out, due to "too long of a query string" which happens to also be too long of a url.
I cannot merely remove the viewstate variable - I need it. But I need to pass the viewstate variable along via some method other than get when the form is submitted, while the other inputs of the form (the non-hidden inputs) are appended to the query string.

I've got three forms, one is a search form where you use textboxes to filter the datagridview to find the Client you wish to work on.The second form is basic data entry, their personal details, assets, liabilities, etc is entered on this form.The third form calculates all sorts of reports about the particular client.I filter the binding sources each time to get the appropriate clients data on the form when the particular client is chosen in the first form.When I go to print the word document I create at the button.click event, it comes up with an error saying "Conversion from string "" to type 'Integer' is not valid. I've checked countless times, tabbed in and out of the textbox, named ClientIDTextbox, but it still wont accept that there is a value in that textbox - the error is appearing on the line where I use the textbox to query data from the database using the ID in the textbox.The third form holds the print button, and the second form holds the ClientIDTextbox which is causing this error.
I'm about to try querying the binding source, instead of applying a filter, using ClientBindingSource.DataSource = dt where dt is a datatable. I'll let you know how this goes! But in the meantime, is it because I've filtered the binding source multiple times across forms that the error is appearing?
I am still developing this function, but here is what I am intending it to do. This function will accept an Object, then try to determine its type.
