As far as I can tell, if i want to append data to a RTF from a RTB, the only way is to load the RTF into a RTB, add the next text to the RTB, and then SaveFile the RTB which overwrites the original RTF.
View 7 RepliesThey are numerous examples of using SaveFileDialog mainly on simple textboxes. However, I have in my resources an Excel SpreadSheet. I want to allow the use to select the destination where he can save this spreadsheet. He is not allowed to change the name of the file in the filename. Afterwards, I want to copy the file from my resources and save it to the user's selected destination. How can I do that?

View 2 RepliesI'm a newbie writing my first app. I need help with the following: I need to retrieve the logged in user which = GID, I then need to append it to a URL which will start our Help Desk chat client. I can retrieve the GID easy enough but can't figure out how to append it and pass it with the URL. I found a post which instructed to declare the url as a string also and concatenate it. The UserName would follow the ":" at the end of the Url.

Pretty new to VB.Net. Having a bit of trouble here with something I though should be simple.Keeping it simple. Let's say i have a Document table with "Name" that I want to search on (in reality there are several other tables, joins, etc ..). I need to be able to build the query where clause based on string values passed in.
Example - user may pass in "ABC" or "ABC DEF" or "ABC DEF GHI".The final query would be (syntax not correct i know)Select * from Documents Where Name Like %ABC% AND Name Like %DEF% AND Name like %GHI%
So, I though I could do something like this.
Dim query = From document In _context.Documents
<< loop based on number of strings passed in >>
query = query.Where( ... what goes here?? )
For some reason, being brain dead or something, I can't figure out how to make this work in VB.Net, or if I'm doing it correctly.
I am trying to append a table to database using ADOX in .NET (as you probably surmised from the topic title) I get the following error:
Create Database Failure: System.Runtime.InteropServices.COMException (0x80040E3D): Type is invalid.
It says the Type is Invalid on the line where I try to append the objTable to the Catalog
And here is the code I am using:

I am new to Vb.net so I will need some handholding. I have been searching everywhere but can't find what I need.I'm creating an app that has two forms.Each form has two comboboxes.The comboboxes are populated via a list and the list is populated by reading a text file for each combobox.The second form is called from the main form to modify the entries in the comboboxes. When I select the displaymember in the combobox a value corresponding to that entry is displayed in the text box.Now here is what I need.
I need to be able to append new values to the list so when focus is returned to the main form the new value is present. I'm using a combobox and a textbox on the second form as the import.The combobox is used to either select a present value to be able to modify the value in the textbox, or is used to add a new list element.

I am attempting to append information to a textbox in VB. My app allows the user to choose a variety of options and displays all the information in a single, read-only text box.
I would like to set it up so every time an event triggers something to be written in the text box, it gets appended instead of overwriting the text currently in the box.
The only constraint is that text should be appended as a new line, not directly after the last sentence.

The above code works fine, but the problem is it overwrites the Quiz0.txt file's text. I want it to append the (";" & TbxOutput.Text & ";" & answrstrng) thing to what is already written in the Quiz0.txt file so that I can use the button (which runs this code) multiple times to add to the Quiz0.txt file.
I don't have a problem but I;m asking you something on the in VB.net.code. So in brief, this means that apart from 'Create', the 'Append' also create a file when it does not exist then?

I need to set the color of the font every time I add text to the RichTextBox
I'm using. RtbResults.AppendText(DisplayPacket)
To add a new line of text, but each line needs to be a set color.I found this on the net but it doesn't seem to work in my VS11b RtbResults.AppendText(DisplayPacket,forecolor,backcolor,font)
Are these the correct overloads? can I do this another way if this doesn't work?I don't want to have to insert the text then go back and select and change its color.
I am creating a report and outputting the results to an excel file. Here is how it is suppose to work. I have a table called EMPID that has a list of employee id's. I loop through this table and for each EMPID, I run several queries. I would like to append the data that is returned to the spreadsheet so that the results for all EMPID's would be added to the spreadsheet. Right now, the way I have coded it, for each EMPID it overwrites the fields in the spreadsheet instead of adding/appending them to it.
Here is some code:
If EmpidDS.Tables("EMPID_Table").Rows.Count <> 0 Then
For Each dr As System.Data.DataRow In EmpidDS.Tables("EMPID_Table").Rows
'Set the variable EMPID to the current row EMPID
EMPID = dr.Item("EMPID")
'Check that table is not empty

I need to capture the last 5 lines from my "write to log" function so I can add it to a debug email. I can't think of an easy way to do this.
I did think I could have an array with 5 items in it, but I'd still need to shuffle the existing items to add the current data.
