My VB.NET (3.5) application generates Excel reports. Newer versions of Excel support the Office Open XML file format, while older versions don't.
I'd like my application to identify which version of Excel is installed on the local machine, and use a different method for generating the report (Newer versions: by generating an XML file. Older versions: by utilizing Excel Automation).
How can I identify the Excel version installed on the local machine?
I want to order the rows by the 'Budget%' column in descending order.
The Code I have so far is:
Dim objExcel As New Excel.Application Dim objWorkbook As Excel.Workbook Dim objSheet As Excel.Worksheet objExcel.WindowState = Excel.XlWindowState.xlMinimized objExcel.Visible = False
I am using Excel 2007, VS2008 Pro.I am building a VSTO Add-in that requires "drag and drop from Excel cells to a drag-enabled task pane".So far I notice that I can only drag and drop within the cells themselves. It does not allow me to drop into the task Pane or drag past the sheet limits.(http:)[url]...
Note: The task pane has drag drop enabled, I ahve already tested I can drag/drop from task pane to excel but I need to do this the other way around?
I am going to develop a windows application tool. the tool will be developed on VS2008. i have the functionality of exporting the data to excel. So in my machine i have office 2003. so i am going to reference the excel library11. so it will work in my machine. If i deploy this tool on the destination machine which has office2000 or office 2007 will this export to excel functionlality work?If means what should i do to avoid this version depedency?
I have Office 2007 on my system. The client has Office 2003 on his system. Is it possible to "link" to both versions of Office from VB?It only gives me the capability to reference to my Office version, I'd like to be able to make it fully compatible with both versions of Office.
I have several excel sheets which I'd like to work with different Excel versions using VB.NET Basically, I want to choose which Excel version I will open certain worksheet using VB.NET. Is there any way to know which Excel version is installed in the machine and how many versions with VB.NET? And how do I choose which Excel version I will open it?
I'd like to know it through programming, I know that this can be done if you take a look at the registry keys in the machine. Although, what I need is to create a software that asks the user for the Excel version he want to open
With XP set to a language such as Spanish (Spain), the VBA-in-Excel function "Excel.Version" returns the text string "11.0" (not "11,1"). It does not respect the language setting.
"CLng(Excel.Version)" then produces the value "110" (wrong!), perhaps because CLng respects the language setting and is looking for a comma instead of a period.
The work-around is easy. But I need to know if switching to another language requires a setting that my client in Spain missed, or is this just a bug.
If it is a bug, is the problem limited to this one function (Excel.Version), or are there other functions that return values in text format that are affected?
In my computer excel 2003 is installed. My code runs well in my computer but failed in another computer which only has excel 2007. If I want to make my code still functions in excel 2007, I heard of that something like late binding but I haven't experienced with that and not sure.
I need to be able to detect which version of Excel I have installed in my machine from some .NET code I'm developing. I'm currently using Application.Version for that, but it doesn't give me information about Service Packs.
I have 2003 xls file which is saved on a web share point. File combines vbs functionalities, of which one is uploading data to this file (from another file on the same share point) by clicking command button.When I open file from my location it all functionalities are working without problems. My customer is running it from his location, he is also using Excel 2003, the moment he wants to upload the data he gets the bug.
Message: Method "Worksheets" of object "_Global" failed
I checked and it seems that in the references he has 10.0 object library and I have 11.0 What i can do to unify the coding so it is indifferent from Object Library version?I have read about late va early binding, I guess i'm using late binding I also check that i can adjust late binding buy standard codes.
Dim oExcel As Object Dim oWorkbook As Object Dim oWorksheet As Object
I have Visual Studio 2010 and a VB Project that had a reference to Microsoft.Interop.Excel 12.0. Well recently I changed the reference version to 14.0. That was actually a mistake and now I need to bump it back down to version 12.0. However I get this error in my project now...
Project 'MyProject' requires a reference to version '14.0.0.0' of assembly 'Microsoft.Office.Interop.Excel', but references version '12.0.0.0' of assembly 'Microsoft.Office.Interop.Excel'.
I tried removing references and adding the com object to, but no avail.
[code]I have this XML file, how do i get the ID attribute? this question is not about "how to get attributes in xml's", i've found several solutions, but somehow i can't address to this specific attribute in this specific node.i can get info inside tables that are within "infNF" and i'm loading it into a dataset and using this code: ds.Tables(Table).Rows(row)(node)is there a similar way to do what i want to get THIS attribute?
I'd like my application to be able to detect a where a particular USB device has been mounted, and adapt accordingly. Ideally, I'd associate paths with a USB serial number, rather than with a given path. However, I cannot figure out a simple way to access these unique IDs from VB.Net code.
I have a question that relates to identifying words or characters in text boxes.Okay, I know that I can identify the entire text with textbox1.text = "~~~~". But say I want to search for a specific part.e.i.(in textbox)Hello, how are you?(in textbox)How, in code, would I find and select, let's say, the word "how"?Please, if you can help, I need it. I want to learn as much as I can about Visual Basic so I can become a better programmer.
The basic question is can I assign a variable to represent a control? As an example which of 12 tickBoxes have been ticked. Is this possible with a for next loop?
Is there an automated tool for VB.Net that will identify all global variables in a project?Short of that, is there any scripts that can be used that will facilitate a manual review of global variables?There seems to be tools for C/C++, but not for VB.Net:Tools to find global/static variables in C codebases there a tool to list global variables used and output by a C function?
EDIT: My current approach uses the following VS REGEX searches: For finding global variables:
In the dgv_CellEndEdit event I know I can find which cell I'm in by the "CurrentCell.ColumnIndex" property. I'd like to be able to check the current column name. If I use "columnIndex" and a column is added or deleted this could cause errors.
I have a table of data exported to an Excel file that contains a Date/Time Field. The entries in the table are formatted like 01/01/2009 14:00 (military time). Every line in the table contains unique information that is specific to that particular date/time information, 1800 lines of data (the reason that I dont want to hand sort this table). How can I identify the items in the table that fall after a particular time of day? More specifically, I need to identify which of the data fields have a time after 14:00 on that particular day.
What conditional statement is used to identify if username.text is empty or password.text is empty or both is empty then prompt a msgbox that tells what part is empty. My attempt was bad and my first time to use select case. [code]
I've been trying to complete a program that I have to write for a class but keep getting an error that when double clicked, takes me to the Application.Designer.vb screen. The error that shows up in the Error List is "Employee' is a type in 'WindowsApplication1' and cannot be used as an expression." The resources I've tried to use (book and web) have been no help. Does anyone know what needs to be done to correct this error so I can test my program and correct any other possible errors? I can also provide the code for the program, if that will be any help. Here is the code that shows up in the Designer window:
My issue is regarding overloaded functions of the already provided IIf function that would handle specific types. As you all know the IIf function provided returns objects, rather a specific type so for my needs I created a few overloaded function to do just that but with a specific type in mind. So having said I have IIf functions for types of booleans, strings, bytes, integers, etc etc.
Now my problem is when I'm trying to pass a byte value to this function that would return one of the two byte values. When I do this the designer keeps confusing my values as an integer value and calls for me to convert it to a byte. If I did this then it would defeat my entire purpose for creating these functions-which is to avoid any conversions. The only way I can solve this is by converting the whole statement itself or the true/false parameter parts individual to specify to the designer that these values are bytes. I'm just hoping there's a way of identifying the difference between bytes and integers..
Is there any way to make my programs use a lower version of net.framework other than the newest version 4 that comes with VS2010?I use my programs within a closed network and there isn't an easy way for me to install any software since I'm not the administrator.
I'm trying to add functionality to my application that will disable buttons and checkboxes depending on what version the OS is when the app is launched. I made a test app to test this but unfortunately I can not get it to work. Here is my code:
'OS Check Dim osValue As Object osValue = My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrent Version", "CurrentVersion", "5.2")
[Code]...
*Note - 5.2 is Windows 2003, 6.0 is Vista, 5.1 is Windows XP
I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?
I have a XML file with the latest application version number, I have this loaded into a variable, how can i compare this against the application.info.version to see if it's the latest version??
I want my application to do something special :D.. jks
I just want it to compare assembly version to the file version something like this (btw i also want it if it is the same i want it to enable a button):
Private Sub StartSplash_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load If Assembly Version = File Version Then
[Code].....
so how do i detect Assembly & File version numbers?
