Opening A .dwg File?
Jun 7, 2010
My program performs a search on a specific directory and returns a list of files with specific criteria. When the user selects a file name in the list box and Clicks the button, I want the program to open that file and print it. I have two functions - one store the file path in a text box and the other gives me an option to select the printer. have no idea how to open the file using that path and how to get it print.If i specify the hard code the a specific file path, it currently can open all files except a .dwg file. For a .dwg file, my program opens auto-cad and crashes?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
For Each file In LstSelected.Items

I have a program that can save user's input into a text file and load it back, but whenever I try to open the file and exit without selecting the file I get an error.(if i select the file and open it i don't get any errors).
This is the code that handles text file loading:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
OpenFileDialog1.InitialDirectory = "C:"
OpenFileDialog1.Filter = "Text Files ONLY (*.txt) | *.txt"
OpenFileDialog1.ShowDialog()
[CODE]...
The error is :"FileNotFoundException was unhandled. Could not find file at xxx". also I would like to know how to make it so that the initial file name for file saving is today's date. I do not get any errors when I try to save the file.

I need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.

I'm having a slight problem getting my program to load a save file when double clicking the save file.I'm using the Command$() to get the command line argument. I can open a save file by dragging it onto the exe. But not by double clicking the save file (after it's associated with the exe).I though dragging and dropping a file on a program and double clicking the file would open it in the same way, but I guess not.So in short how does file association work and how do I get the file path set to a var when the program loads.

I got a log file (Log.txt) a timer and a RichTextBox1.Text The timer is opening the log file again and again every milisecond here the code:
Code:
Okay that keeps the track of my log file inside my richtextbox , but there is a big problem there. My richtextbox slows down hard if the log file gets too big.. Sometimes it kicks me out of the program and in taskbar it says Program Not Responding..
I wanted to know if there is a method to read a bigger Log file with out having such issues. (It mostly happens when log file goes over 13000 characters)

I am using VB.net 2005 and I have a timer running on form1 that communicates modbus with a relay io board. There should be constant uninterrupted communication between the two devices and that is working until I open the data logging form2 and import data from a large sequential text file. While I am parsing data, the timer from form1 stops communicating with the modbus device. Once the data is done, the timer of form1 resumes communication with the modbus device. Is there some other method I could use to make sure the modbus communication is never interrupted.? Is there a command I can periodically run from form2 while the data is being parsed that will keep the timer on form1running?

My application generates XLSX files based on a users requirements.
After the XLSX file is generated the user is redirected to where the file is saved using Response.Redirect...
Response.Redirect("filename.xlsx")
When the user then opens the file... they recieve this message.
The file you are trying to open, 'filename.xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
As a temporary fix I've instructed my users to press "Yes" when they receive this message and the file opens perfectly fine.
Does anyone have any ideas why IE6 is trying to open an XLSX file as an XLS?

I am developing an Excel workbook at work and I've got a problem. I'd like to save information entered in the workbook and save it in another one (called List, for example purposes), using a macro. The problem is that the file in which I want to save the information is located on a server. When people open List.xls, it's Read Only. So, when my macro executes, it opens a Read Only workbook...I'd like to do "Open As", just like you could do by right-clicking on any file in Windows XP. The result would be that the macro would log on as administrator only to open List.xls, write in it and save it under the same name.

My company is currently using a Linux/Powerterm program that exports reports via email on a daily basis. I have a add-in program installed on outlook to automatically save the report to a folder on the server. The file that is exported appears to be an XLS 97-2003 Worksheet, but I confirmed from the original programmer that this file is not a true Excel file, I believe it is a unicode file, but it can be opened by Excel. I want to link these files to an Access database within my form, but Access does not recognize this file format.I attempted to create several programs in Studio to convert the file to an XLSX file, but on each attempt I receive an error the file is an in unrecognizable format which is killing me at the moment. I even made attempts to dump the data to an dgv but it still wont be accepted.

I apparently didn't save the project I was working on as a "solution" file, and I all I have are two separate files.[code]I only have those two files. The code is there, but the solution explorer lists nothing, and I have found no option to just simply open up my project after saving it so I can work on it again. I see no design. I really just want to see my project like it was before.
